# Acknowledge a CLI webhook event

`POST /v1/webhooks/{id}/events/{event_id}/ack`

## Request

- Base URL: `https://api.creem.io`
- URL: `https://api.creem.io/v1/webhooks/{id}/events/{event_id}/ack`
- Auth: API key in header `x-api-key`
- TypeScript: <https://skmtc.dev/creem/apis/creem-api/docs/v1/webhooks/:id/events/:event_id/ack/post.ts> (a function with typed inputs; its response is checked against the schema)

Report the status your local server returned for an event from the pending feed. Any 2xx marks the delivery successful; anything else records a failure. Acknowledged events leave the pending feed and appear in the dashboard event log with the reported result. Only valid for endpoints created with `delivery_mode: cli`.

## Path parameters

- `id` string, required
- `event_id` string, required

## Request body

- AcknowledgeWebhookEventRequestEntity
  - `status_code` number, required: The HTTP status code the local server answered with. Any 2xx marks the delivery successful. Report 503 when the local server could not be reached.
  - `response_body` string: The response body the local server returned, truncated to 10,000 characters. Shown in the dashboard event log.

## Response `200`

Successfully acknowledged the event

- WebhookEventAckEntity
  - `id` string, required: The acknowledged event ID.
  - `object` string, required: A string representing the object’s type. Objects of the same type share the same value.
  - `success` boolean, required: Whether the first acknowledgment recorded a successful delivery (any 2xx). Repeated acknowledgments return the stored result.

## Other responses
