How to Automate Drupal Blog Posts with n8n, OpenAI & Google Sheets

Writing a blog post involves more than generating text. You need a topic, an article, a relevant image, correctly populated CMS fields, and a way to record what has already been published. Repeating those steps manually becomes time-consuming when you publish regularly. If you want to automate Drupal blog posts from start to finish, n8n can handle every one of those steps for you.

This tutorial shows you how to automate Drupal 11 blog posts with n8n, OpenAI, and Google Sheets. You will build a workflow that selects one pending topic, writes an article, generates a cover image, uploads the image through Drupal’s REST API, creates the content, and marks the spreadsheet row as done.

The guide follows the demonstrated workflow, with several practical corrections for reuse: Basic Authentication is separated from optional OAuth configuration, the publishing status is explicit, and all account-specific URLs and credential references in the downloadable JSON are placeholders. The final section contains the complete workflow JSON. By the end, you will have a reusable system to automate Drupal blog posts on a schedule.

What you will build to automate Drupal blog posts

The chat model and structured output parser are attached to the AI Agent through their dedicated connections. They are not separate steps in the main execution line. The main line runs from the trigger through the spreadsheet update.

This template processes one article per execution. It does not include web research, a factual verification agent, manual approval, retries with duplicate protection, or social posting. Those are extensions discussed later. A prompt requesting accurate information is not a substitute for source verification.

Step 1: Prepare the required accounts and services

• A working Drupal 11 site with an HTTPS URL reachable from the n8n server.
• An n8n installation with the Google Sheets, OpenAI, AI Agent, Structured Output Parser, Edit Image, and HTTP Request nodes used by the export.
• An OpenAI API project with billing and access to the text and image models you select.
• A Google account that can read and edit the topic spreadsheet.
• Drupal administration access to configure content fields, REST resources, and a dedicated API user.

The supplied export selects gpt-4.1-mini for text and gpt-image-1 for images. These names are preserved in the public template because they are the models in the source workflow. Check access in your own account and select an available compatible model if needed. API charges depend on usage and model settings; this tutorial does not assume a fixed monthly cost. Choosing the right models up front is the first decision when you automate Drupal blog posts, because it controls both quality and cost.

If Drupal runs on your laptop while n8n runs on a remote server, a localhost URL will not connect to your laptop. Use a reachable HTTPS deployment or configure suitable private networking. Start with a test Drupal site so that you can inspect the output before scheduling publication.

Step 2: Create the Drupal content type and fields

Open Structure → Content types. Create a content type or use an existing one. The example uses the machine name pages. This is a custom example: Drupal’s standard Basic page type usually has the machine name page, which is different.

Open Manage fields and confirm the actual machine names. If your article text is stored in body, replace field_description in the Post Article request. If your image uses field_cover, change both the upload URL and the node payload. The workflow does not create these Drupal fields for you.

Configure the image field to accept the file types and maximum size you plan to upload. The example uses a PNG filename. If your generated binary is JPEG or WebP, use the matching extension and allow that type in the field. Do not simply rename a JPEG file to PNG.

Under Manage display, make the article text and cover image visible in the intended view mode. A successful API response does not guarantee that the theme displays every field.

Step 3: Enable Drupal REST and Basic Authentication

The HTTP Request nodes in this workflow use Drupal’s core REST endpoints with Basic Authentication. They do not call JSON:API endpoints and do not request an OAuth access token. You do not need Consumers, Simple OAuth, an OAuth client, scopes, or signing keys for this Basic Authentication version.

Enable the core RESTful Web Services, Serialization, and HTTP Basic Authentication modules. REST UI is a contributed module that provides a convenient configuration screen. With Composer and Drush available, run the following from your Drupal project directory:

composer require drupal/restui
vendor/bin/drush en rest serialization basic_auth restui -y
vendor/bin/drush cr

If you do not use Drush, install REST UI through your project’s normal dependency process and enable the modules on Drupal’s Extend screen. The underlying REST resources can also be configured through YAML, but this tutorial uses REST UI.

Visit Configuration → Web services → REST, usually /admin/config/services/rest. Enable the following resources and configure POST, JSON, and Basic Authentication as applicable:

Select the File upload resource for binary upload. Enabling only the generic File entity resource is not the same configuration. There is no need to enable the User resource, DELETE, or PATCH solely to run this tutorial.

Drupal lets each REST resource specify its authentication and serialization settings. See the official REST API overview and authentication documentation for the underlying configuration model.

Step 4: Create a dedicated Drupal API user

1. Open People → Roles and create a role such as Blog API Writer.
2. Allow the role to create content of the chosen type and use the selected text format. Grant field access required by any field-permission modules installed on your site.
3. Create an active user such as blog_api_user and assign this role. Use a strong unique password.
4. Check that the role can create the chosen content type and populate its text and image fields. Avoid assigning the administrator role just to resolve a permission error.

Drupal’s entity and field access rules still apply when a request arrives through REST. For the file-upload resource, access depends on the target field and bundle. On a standard setup, uploading a cover image for this workflow is tied to being allowed to create the relevant content and access its image field.

Choose the text format deliberately

The template sends basic_html. Check Configuration → Content authoring → Text formats and editors. The selected format must allow the markup you want to retain, such as headings, paragraphs, lists, links, and <pre><code> for programming examples. Its exact allowed tags depend on your site configuration.

If you create a restricted automation-specific format, update the format value in the request and grant the API role permission to use it. Do not switch to unrestricted HTML simply to make AI-generated markup appear. Review and filter the allowed elements.

Step 5: Create the Google Sheets topic queue

Create a spreadsheet with a tab named Sheet1. Add these headers to the first row:

Use lowercase pending and done consistently. The fetch node filters by the exact configured value. For your first test, add only one pending row so that it is easy to track the article being processed.

The Google Sheets node returns a row_number value that the final node uses to update the same row. You normally do not create a physical row_number column in the spreadsheet for this setup. Confirm that the value appears in the Fetch Topics output.

The pending/done approach prevents already completed rows from being selected during normal sequential runs. It does not prevent duplicate posts if two executions fetch the same pending row, or if Drupal creates the post but the final spreadsheet update fails. Production safeguards are covered below. Even so, a simple status column is the easiest way to automate Drupal blog posts without losing track of what has already been published.

Step 6: Import the workflow and reconnect credentials

1. Download the sanitized JSON or copy the complete JSON from the final section into a file named drupal-n8n-workflow-public.json.
2. In n8n, create or open a workflow and use the workflow menu’s import-from-file option. Interface labels can vary by release.
3. Keep the workflow inactive while configuring and testing it.
4. Open each credential-using node and select a real credential created in your own n8n instance. The dummy credential IDs cannot authenticate.

For Google OAuth on a self-hosted installation, use the callback URL displayed by n8n when configuring the OAuth client and complete the consent flow. Your authorized account must have edit access to the spreadsheet. Never place API keys, OAuth secrets, passwords, or an encoded Basic Authorization header directly inside the workflow body.

The public export replaces the original domain with https://drupal.example.com, the spreadsheet ID with YOUR_GOOGLE_SHEET_ID, and credential IDs/names with obvious placeholders. It removes cached spreadsheet URLs and original workflow/instance identifiers. Node IDs have been regenerated; names and connections are preserved.

Step 7: Configure the schedule

Open Schedule Trigger. The source export contains daysInterval: 7 and triggerAtHour: 18. Verify the visible trigger settings after import and explicitly select the interval you intend to use; defaults and scheduling behavior can vary between n8n versions. A weekly schedule is a safe starting point when you first automate Drupal blog posts, because it gives you time to review each result.

For a once-a-week workflow, set a weekly schedule and choose the desired day and hour. Open the workflow settings and select the correct timezone, such as Asia/Karachi. Do not assume that the server timezone matches your local time.

Run the workflow manually during setup. After testing, save and publish or activate it using the controls in your n8n version. The Schedule Trigger documentation explains publication and scheduling behavior.

Step 8: Configure Fetch Topics

1. Select your Google Sheets credential.
2. Replace YOUR_GOOGLE_SHEET_ID with the ID from your spreadsheet URL. In https://docs.google.com/spreadsheets/d/YOUR_GOOGLE_SHEET_ID/edit, it is the value between /d/ and /edit.
3. Select the Sheet1 tab, or enter your actual tab name.
4. Use the operation that reads rows from a sheet.
5. Set the filter column to status and the filter value to pending.
6. Enable the option to return only the first matching row.
7. Execute the node and inspect its output.

{
  "row_number": 2,
  "title": "How to create a custom Drupal 11 block",
  "status": "pending"
}

If no pending rows exist, the node may produce no items and the downstream steps will not run. That is a valid empty-queue result. If you want an explicit notification, add a dedicated no-work branch instead of generating an article with a missing title.

Step 9: Configure the AI Agent and article model

Open AI Agent. Its user prompt references the topic from the previous node:

{{ $json.title }}

Keep persistent writing rules in the system message and topic-specific instructions in the user prompt. The public template requests useful, accurate technical content with HTML paragraphs, H2/H3 headings, lists, and explained code examples. It asks for roughly 2,000–3,000 words only where appropriate, rather than padding every topic to meet a fixed length.

The original prompt referred to WordPress and asked for an H1 inside the generated article. In this Drupal workflow, the node title normally provides the page heading, so the public prompt starts the article body with an introductory paragraph and uses H2/H3 headings beneath it. The article you are reading is formatted for WordPress, but the workflow itself publishes to Drupal.

Open Write Article, select your OpenAI credential, and confirm the model. This node connects to the AI Agent through the language-model connector. Check the resulting article for incomplete sections, incorrect API details, and unsafe code examples before enabling unattended publishing.

Configure structured output

The Structured Output parser uses the following example. Keep the keys identical because later nodes reference them:

{
  "post_title": "Article title",
  "post_content": "<p>Article introduction...</p><h2>First section</h2>",
  "post_keywords": "Drupal 11, REST API, automation"
}

The AI Agent output should expose these values beneath output. For example:

{{ $('AI Agent').item.json.output.post_title }}
{{ $('AI Agent').item.json.output.post_content }}
{{ $('AI Agent').item.json.output.post_keywords }}

The current node payload stores the title and content, but it does not map post_keywords into Drupal. To save keywords as taxonomy terms or SEO fields, add suitable Drupal fields and explicit mappings. Generating a keyword string does not automatically populate Metatag or create taxonomy references. Clean structured output is what lets you automate Drupal blog posts reliably instead of fixing broken fields by hand.

Step 10: Generate the blog cover image

Open Generate Image, choose the OpenAI credential, and inspect the image resource settings. The export uses gpt-image-1 with a configured output size of 1536x1024. The prompt references the generated article title:

{{ $('AI Agent').item.json.output.post_title }}

Describe the visual subject, composition, and palette clearly. The public template requests a clean technology-related illustration with room for cropping. It avoids small text and watermarks. The actual API size setting controls generation dimensions; writing “1100 × 650” in a prompt does not override that setting.

Run this node and inspect the Binary output. The following nodes expect image bytes under a binary property named data. If your node configuration produces a URL instead, add an HTTP Request step to download that URL as a file and store the result under data. If it returns base64 text, convert that text into a binary file before resizing.

Step 11: Resize the image

Open Resize. The exported Edit Image node uses width 1100 and height 650. Confirm the binary input property is data and inspect the actual image dimensions after execution.

A 1536 × 1024 image has a different aspect ratio from 1100 × 650. Choose a resize strategy deliberately: fit inside the target area to preserve the entire image, or resize and crop if exact cover dimensions are required. Ignoring aspect ratio can distort the artwork. The source export does not explicitly select a fit/crop policy, so the guide does not assume it produces an exact crop.

If Edit Image fails on a self-hosted installation, check its GraphicsMagick dependency and binary input configuration. The Edit Image documentation describes the supported resize options and dependencies.

Step 12: Upload the image to Drupal

Open Upload Image1. Replace the dummy domain and confirm the content type and image-field machine names in this endpoint:

https://drupal.example.com/file/upload/node/pages/field_image?_format=json

Set the headers below. The filename must match the format of your actual binary image:

Content-Disposition: file; filename="image.png"
Accept: application/json
Content-Type: application/octet-stream

Send raw image bytes in the request body. Do not wrap the binary in JSON, send a local file path, or switch this request to multipart form data. Drupal validates the upload against the target image field’s rules. The Drupal file-upload resource documentation describes this endpoint and the subsequent file-reference step.

A successful response includes a file entity with an ID. The following is an abbreviated example:

{
  "fid": [{"value": 123}],
  "filename": [{"value": "image.png"}],
  "filemime": [{"value": "image/png"}]
}

The next node reads fid[0].value. Uploading alone does not attach the image to an article; the node-creation request must reference this ID. Keep the HTTP response configured to return the JSON body directly, or adjust the expression if you enable a response wrapper containing headers and status. Once the upload returns a valid file ID, the hardest part of the process to automate Drupal blog posts is done.

Step 13: Create the Drupal article and attach its image

Open Post Article and set the URL to:

https://drupal.example.com/node?_format=json

Use POST and select the same HTTP Basic Auth credential. Set Accept: application/json and Content-Type: application/json. Let n8n generate the Authorization header from the credential; do not add a second hard-coded Authorization header.

Select JSON for the request body and use this expression-enabled template. If the editor has a separate Expression mode, paste the body there; the workflow export represents an expression string with a leading equals sign.

{
  "type": [
    {
      "target_id": "pages"
    }
  ],
  "status": [{"value": true}],
  "title": [
    {
      "value": {{ JSON.stringify($('AI Agent').item.json.output.post_title) }}
    }
  ],
  "field_description": [
    {
      "value": {{ JSON.stringify($('AI Agent').item.json.output.post_content) }},
      "format": "basic_html"
    }
  ],
  "field_image": [
    {
      "target_id": {{ $json.fid[0].value }},
      "alt": {{ JSON.stringify($('AI Agent').item.json.output.post_title) }},
      "title": {{ JSON.stringify($('AI Agent').item.json.output.post_title) }}
    }
  ]
}

This is an n8n expression template, not standalone JSON until n8n evaluates its expressions. JSON.stringify() safely quotes the generated title and HTML so embedded quotes and line breaks do not break the outgoing JSON.

The public template explicitly includes status: true. For your first test, change it to false and inspect the unpublished article in Drupal. If Content Moderation is enabled, follow the site’s moderation states and transition permissions; setting status alone is not a complete moderation workflow.

The export disables redirect following for this request. Use the final canonical HTTPS URL so the POST reaches Drupal directly. A redirect to a login screen or a different domain should be investigated rather than hidden. Publishing as a draft first is a sensible default while you test how well your workflow can automate Drupal blog posts.

Step 14: Update the original spreadsheet row

Open Update row in sheet. Select the same spreadsheet, tab, and Google credential used by Fetch Topics. Choose the row-update operation and map the matching row number from the original fetch:

{{ $('Fetch Topics').item.json.row_number }}

Match on row_number and set status to done. The final node should remain connected after Post Article so that an unsuccessful node-creation request does not normally mark the topic as complete. Keep error handling configured to stop on failure unless you add an explicit alternative path.

Do not sort or insert rows while a run is in progress if you rely on row numbers. For a more reliable queue, add a stable topic ID and store the resulting Drupal node ID, URL, and completion time. That makes reconciliation easier if a workflow is interrupted.

Step 15: Test the complete workflow

1. Confirm there is exactly one test topic marked pending.
2. Execute Fetch Topics and verify title and row_number.
3. Execute the AI Agent and inspect all three parsed fields.
4. Generate and resize the image; inspect its binary property, filename, and dimensions.
5. Upload the image and confirm that the response contains fid[0].value.
6. Create the Drupal node, initially with status set to false if you want an unpublished test.
7. Open the node as an authorized editor and verify the title, HTML formatting, code blocks, image, and image alt text.
8. Confirm that the original spreadsheet row becomes done.
9. Review the result and API usage, then choose your publication behavior and enable the schedule.

Avoid rerunning the node-creation step casually: each successful POST can create another node. During troubleshooting, record the created node ID and check Drupal before retrying after a timeout. Run several manual tests before you rely on the schedule to automate Drupal blog posts unattended.

Troubleshooting common issues when you automate Drupal blog posts

This setup uses stateless Basic Authentication over HTTPS. If you intentionally change to session-cookie authentication, the write requests also need the appropriate CSRF-token handling. Do not mix browser-session instructions into the Basic Auth workflow without changing the authentication design.

Production improvements to add next

Add review and approval before publishing

Insert a review stage after article generation. A reviewer can check technical claims, missing steps, formatting, and consistency with supplied references. If you need current research, add an explicit retrieval stage and retain source URLs; the existing agent has no research tool attached. AI review can still miss mistakes, so use manual approval for content that requires editorial judgment.

An email approval process needs more than a Send Email node. Store the article’s identity, pause the workflow, collect an authenticated approval or rejection, and resume only the approved item. Alternatively, create Drupal drafts and use Drupal’s existing editorial workflow.

Make retries safe

Use a durable content ID and keep a record of the Drupal node created for it. Prevent simultaneous runs from claiming the same topic. A pending → processing → done status is useful, but Google Sheets updates alone are not an atomic queue lock. For concurrent publishing, use a transactional queue or another reliable locking mechanism.

If the create request times out after Drupal has accepted it, verify whether the node already exists before sending another POST. Also handle uploaded files that were not attached because a later step failed.

Improve observability and content quality

• Log the topic ID, node ID, publication URL, timestamp, status, and error message.
• Validate that the title and body are nonempty before generating an image or calling Drupal.
• Add realistic request timeouts and targeted retries for transient failures.
• Generate meaningful image alt text separately instead of always copying the title.
• Map keywords or SEO metadata only after defining the corresponding Drupal fields.
• Track model and image usage so publishing frequency matches your budget.
• Keep secrets inside n8n credentials and review exported workflows before sharing.

Frequently asked questions

Can I use a different Drupal content type?

Yes. Change the bundle in the image-upload URL and the node payload’s type value, then update any field machine names. The target bundle must have the fields and permissions the request expects.

Do I need OAuth for this workflow?

No. This export authenticates using a Drupal username and password through n8n’s HTTP Basic Auth credential. OAuth is a separate authentication option and requires its own token flow and resource configuration.

Does this publish to WordPress?

No. This guide is prepared for a WordPress blog post, but its automation publishes to Drupal. A WordPress automation would need different REST endpoints, authentication, media handling, and post payloads.

Will this guarantee SEO rankings or factual accuracy?

No. The workflow automates content production and delivery. Search performance depends on the usefulness and quality of the content, while technical accuracy requires appropriate sources and review. Longer articles and repeated keywords do not provide a ranking guarantee. Use the workflow to automate Drupal blog posts, not to replace editorial review.

Can I replace Google Sheets with RSS?

Yes, but you must add feed retrieval, topic selection, duplicate detection, and source tracking. The supplied template uses an editorial topic queue; it does not contain an RSS branch.

Complete n8n workflow JSON to automate Drupal blog posts

Copy the following JSON into a .json file and import it into n8n. Replace the dummy domain and spreadsheet ID, reselect all three credential types, verify the imported node settings, and test before enabling the schedule. The workflow is inactive by default.

This public version preserves the original node layout and main connections. It removes the embedded Authorization value and private account metadata, updates the article prompt for Drupal, clarifies the image prompt, adds an explicit JSON Content-Type header, and explicitly requests published status. Change status to false for draft testing. The JSON has been checked for syntax and internal connection consistency; it has not been executed against your services.
