How do I authenticate with the API?

Include your API key in the Authorization header: Authorization: Bearer YOUR_API_KEY. Generate API keys from your DocsAutomator workspace settings.

What's the difference between sync and async mode?

In sync mode (default), the API waits up to 5 minutes for the document to be generated and returns the result. In async mode (pass async: true), the API returns immediately with a job ID that you can poll for progress.

How do I pass line item data?

Pass line items as JSON arrays in the data payload. Use a "children" key to nest sub-items up to 3 levels deep. DocsAutomator expands the table rows in your template automatically.

What are the rate limits?

500 requests per 15 minutes per API key. Each workspace can queue an unlimited number of jobs with 5 processed concurrently. Overage pricing is available on all paid plans so you never hit a hard wall.

Can I manage automations via API?

Yes. The API includes full CRUD operations for automations: create, list, get, update, duplicate, and delete. You can manage templates, field mappings, and output settings entirely via API without using the web dashboard.

Can I trigger e-signatures from the API?

Yes. If your automation has e-signing enabled, generating a document via API automatically starts the signing workflow. The response includes the signing session ID and signing links for each signer.

Do developers need to update code when templates change?

No. That's one of the biggest advantages of DocsAutomator. Templates live in Google Docs and are fully managed by your business team. When wording changes, branding updates, or new fields are added, your team updates the Google Doc — no code changes, no deploys, no developer involvement needed. The API call stays the same.

Key Benefits

Why teams choose DocsAutomator for REST API

Templates Owned by Business Users

Your team edits templates in Google Docs — no developer involvement needed. When a contract clause changes or a logo is updated, business users handle it themselves. Developers never touch templates.

Simple REST Interface

One POST request generates a document and returns the PDF URL. Bearer token auth, JSON payloads, predictable responses. Integrate in minutes, not days.

Sync & Async Modes

Synchronous mode waits for the document and returns the result. Async mode returns a job ID instantly for polling — perfect for batch workflows or serverless functions.

Webhook Callbacks

Pass a webhook URL and DocsAutomator posts the result when the document is ready. No polling needed — your system is notified the moment generation completes.

API Endpoints

Everything you need to automate documents programmatically

Document Generation

POST /createDocument with your automation ID, data payload, and optional settings. Returns the PDF URL, Google Doc URL, and file ID. Supports line items, conditional rendering, and line deletions.

Automation Management

How it works

Get started in minutes

Create a Template & Automation

Your business team designs the document template in Google Docs. A developer creates an automation in DocsAutomator, sets the data source to "API", and copies the automation ID and API key.

Setting up an API automation in DocsAutomator

Send a POST Request

Send a POST to /createDocument with your automation ID and a JSON data payload. Include field values, line items, and optional settings like webhookUrl or async mode.

Sending an API request to generate a document

Receive Your Document

Get back the PDF URL, Google Doc URL, and file ID in the response. In async mode, poll the job endpoint or receive a webhook when the document is ready.

I've just been looking for this app for weeks. DocsAutomator simply outperforms any competitor out there. I've tried almost every possible way to generate PDF from Airtable, and none offer half of the capacities DocsAutomator does.
