# Trigger automation webhook > Queue a run of a custom automation that has a webhook trigger, instead of waiting for the trigger's configured event. Useful for running automations from CI/CD pipelines, release scripts, or any other system that already emits events. Only custom automations with a webhook trigger can be triggered; other triggers return a `404` response. Authenticate with an organization API key that has write access. 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](/guides/automations-create) 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](/guides/api-automations-trigger). ## 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](https://app.mintlify.com/products/automations) page in your dashboard and click the :icon[settings-2]{icon="settings-2"} 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 ` header template. Replace `` with an unexpired organization API key with write access. Create or manage keys on the [API keys](https://app.mintlify.com/settings/organization/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`: ```yaml .github/workflows/trigger-docs.yml theme={null} 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](/guides/api-update-trigger) and [Trigger automation](/guides/api-automations-trigger): 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](/guides/overview-credits). ## OpenAPI ```yaml admin-openapi.json POST /v2/workflow/{projectId}/{workflowSchemaId}/webhook openapi: 3.0.1 info: title: Mintlify Admin API description: >- An API for administrative operations including documentation updates and agent management. version: 2.0.0 servers: - url: https://api.mintlify.com security: - bearerAuth: [] paths: /v2/workflow/{projectId}/{workflowSchemaId}/webhook: post: summary: Trigger automation webhook description: >- Queue a run of a custom automation that has a webhook trigger, instead of waiting for the trigger's configured event.
