The Clerk Backend API uses secret API keys. You can find and create your instance API keys in Clerk Dashboard API Keys -> Backend API Keys page.
An example request is the following:
-H "Authorization: Bearer test_abc...xyz" \
-H "Content-type: application/json" \
All API requests are subject to a default limit of 50 requests per 10 seconds. Certain endpoints might be subject to different limits, in which case their limits are documented in the endpoint's respective documentation page.
Exceeding the rate limits will result in
429 Too Many RequestsHTTP responses. In that case, the
Retry-Afterheader includes the amount of seconds until the block expires.
