Use this endpoint to trigger a scheduled automation on demand, instead of waiting for its next scheduled run. The automation behaves identically to a regular scheduled run: it picks up everything that has changed since the last completed run.

This endpoint only supports automations configured with a **Custom schedule** trigger. Requests for automations with other triggers, like **Code change** or **Content update**, return a `400` error.

## Use cases [#use-cases]

* **CI/CD pipelines**: Run the **Update from code changes** automation on every merge to `main`, so docs update at your release cadence rather than on a fixed schedule.
* **Release events**: Run the **Draft changelog** automation when you cut a release tag, so the changelog drafts at the same time the release ships.
* **Custom tooling**: Trigger automations from internal tools, Slack commands, or scheduled jobs you already run.

## Find the automation ID [#find-the-automation-id]

Copy the automation ID from the automation's settings panel on the [Automations](https://app.mintlify.com/products/automations) page in your dashboard.

## Example [#example]

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

```yaml title=".github/workflows/trigger-docs.yml"
on:
  push:
    branches: [main]

jobs:
  trigger:
    runs-on: ubuntu-latest
    steps:
      - run: |
          curl -fsS -X POST \
            "https://api.mintlify.com/v1/workflow/$PROJECT_ID/$WORKFLOW_ID/trigger" \
            -H "Authorization: Bearer ${{ secrets.MINTLIFY_API_KEY }}"
        env:
          PROJECT_ID: ${{ vars.MINTLIFY_PROJECT_ID }}
          WORKFLOW_ID: ${{ vars.MINTLIFY_WORKFLOW_ID }}
```

## Rate limits [#rate-limits]

This endpoint shares a rate limit with [Trigger update](/api/update/trigger): up to 10 requests per 10 seconds per organization. Triggered runs consume credits at the same rate as scheduled runs.

`POST /workflow/{projectId}/{workflowSchemaId}/trigger`

Trigger a scheduled automation to run immediately, instead of waiting for its next scheduled time. Useful for running automations from CI/CD pipelines, like a GitHub Action that runs on every merge to your default branch. Only scheduled (custom schedule) automations can be triggered. The run picks up changes since the last completed run, identical to a regular scheduled run.
