Trigger automation webhook

Use this endpoint to run a custom automation with a Webhook trigger. Each request queues a run that uses the automation’s saved prompt and reads the full repository history. This endpoint ignores request bodies.

This endpoint only supports custom automations with a webhook trigger. Predefined automations and automations with any other trigger return a 404 response. To trigger a scheduled custom automation on demand instead, use Trigger automation.

Use cases

• CI/CD pipelines: Run a custom automation on every merge to main or after a release, without waiting for a scheduled run.
• Release events: Run a custom automation from a release script when you cut a tag or publish a new SDK version.
• Internal tooling: Trigger automations from internal dashboards, Slack commands, or scheduled jobs you already run.

Get the webhook URL and auth header

Open the Automations page in your dashboard and click the settings button on a custom automation with a webhook trigger. The trigger card shows the full webhook URL and a Copy auth header action for the Authorization: Bearer <api-key> header template.

Replace <api-key> with an unexpired organization API key with write access. Create or manage keys on the API keys page. Automations do not create, store, or rotate keys on your behalf.

Example

Trigger a webhook automation from a GitHub Action whenever code merges to main:

on:
  push:
    branches: [main]

jobs:
  trigger:
    runs-on: ubuntu-latest
    steps:
      - run: |
          curl -fsS -X POST \
            "https://api.mintlify.com/v2/workflow/$PROJECT_ID/$WORKFLOW_ID/webhook" \
            -H "Authorization: Bearer ${{ secrets.MINTLIFY_API_KEY }}"
        env:
          PROJECT_ID: ${{ vars.MINTLIFY_PROJECT_ID }}
          WORKFLOW_ID: ${{ vars.MINTLIFY_WORKFLOW_ID }}

Rate limits

This endpoint shares a rate limit with Trigger update and Trigger automation: up to 10 requests per 10 seconds per organization. Each queued run consumes credits at the same rate as any other custom automation run. See Credit pricing.
