+## Troubleshooting project services
+
+Some project services use service hooks for integration with external applications. To confirm which ones use service hooks, see the [services table](#services). GitLab stores details of service hook requests made within the last 2 days. To view details of the requests, go to the service's configuration page.
+
+The **Recent Deliveries** section lists the details of each request made within the last 2 days:
+
+- HTTP status code (green for 200-299 codes, red for the others, `internal error` for failed deliveries)
+- Triggered event
+- URL to which the request was sent
+- Elapsed time of the request
+- Relative time in which the request was made
+
+To view more information about the request's execution, click the respective **View details** link.
+On the details page, you can see the data sent by GitLab (request headers and body) and the data received by GitLab (response headers and body).
+
+From this page, you can repeat delivery with the same data by clicking **Resend Request**.
