Where do I find SeleID API authentication, errors and rate limits?

Identify the service and endpoint you want to call. Use a test request and capture its status and request identifier. Handle retryable errors separately from validation and permission errors. If a request is rejected, check credentials, scope and input before retrying. Observe any retry instructions the response supplies.

If a request is rejected, check credentials, scope and input before retrying. Observe any retry instructions the response supplies. Identify the service and endpoint you want to call. If you need help, include the product you were using and the step that failed. Keep passwords, one-time codes and secret keys private.

Use the reference for the specific SeleID service to check how requests authenticate, which errors the API returns and what limits apply. The same account can access multiple services, but each request still needs the credentials, permissions and environment documented for the operation it is trying to perform.
