Review API logs

The API logs tool enables you to take a granular view of your API requests. The API logs tool displays recent API requests by status code, method, request path, private API key (truncated for security), and date.

📘

Data retention

The API logs tool retains 14 days worth of API logs. API logs past this date will be unavailable, although the high-level aggregate information will continue to be stored in the API activity dashboard.

Filter criteria

The API logs can be filtered by endpoint request path, status code, method, and source, including public API key, private API key, or OAuth app. In the additional filter selector, filter by time period, a specified job, trace, or error ID, and API revision.

If no available data matches the given criteria, the dashboard will display No requests available. To reset your filter criteria to the default values, click Clear.

Search endpoint request path

Locate requests made to specific endpoints by pasting in the exact URL path of the endpoint, part of a URL path, or wildcard an ID using brackets, such as {id}.

Valid search examples:

• /api/events - Returns all calls hitting that exact URL path
• /api/events/{id} - Returns all calls hitting that URL path, with ID as a wildcard search
• /api/events/4Gxu5nDJ2qp - Returns all calls hitting that URL path for the exact given ID
• event-bulk-create - Returns /client/event-bulk-create
• events - Returns all paths that include events in the URL path, such as /client/events, /client/event-bulk-create, /api/events, etc.
