Note that you\nmust configure a trigger when you create or deploy a function using the\nGoogle Cloud CLI or the Google Cloud console.\n\nYou can also trigger Cloud Run functions in response to custom events\npublished to an Eventarc channel.\n\nCreate an Eventarc trigger\n--------------------------\n\nCreate an Eventarc trigger so that your\nCloud Run functions service receives notifications of a specific event or\nset of events. By specifying filters for the trigger, you can configure the\nrouting of the event, including the event type and source. For more information\non how to configure an Eventarc trigger for\nCloud Run functions, see [Eventarc triggers](/functions/docs/calling/eventarc).\n\nThe following event types trigger requests to your service:\n\n- [An audit log is created](/eventarc/docs/reference/supported-events#using-cloud-audit-logs) that matches the trigger's filter criteria\n- [A direct event occurs](/eventarc/docs/reference/supported-events#directly-from-a-google-cloud-source) such as an update to a Cloud Storage bucket or an update to a Firebase Remote Config template\n- [A message is published to a Pub/Sub topic](/eventarc/docs/reference/supported-events#using-pubsub)\n\nTrigger functions with custom events\n------------------------------------\n\nYou can trigger Cloud Run functions in response to custom events.\nThese are events produced by special or additional event providers, as opposed\nto the built-in Firebase events supported by the Firebase SDK for\nCloud Run functions, and that are published to an Eventarc\nchannel. For more information, see\n[Create and handle custom event triggers](https://firebase.google.com/docs/functions/beta/custom-events).\nNote that for custom events provided by\n[Firebase Extensions](https://firebase.google.com/docs/extensions/install-extensions),\nyou should refer to the extension's documentation for a list of events (if any)\nthat it publishes. For example, see the\n[event types for the Run Payments with Stripe extension](https://github.com/stripe/stripe-firebase-extensions/blob/98c97775d54fb0be4601864b74d2fe5ce24dab83/firestore-stripe-payments/extension.yaml)."]]
