Retry behavior

The x-fern-retries extension is supported in Python SDKs only.

The x-fern-retries extension configures retry behavior per endpoint in your OpenAPI specification, overriding any retry settings configured by SDK users. Use it to disable retries for non-idempotent operations like payment processing or order creation.

To disable retries for specific endpoints, set disabled: true.

29       responses:

When retries are disabled at the endpoint level, the generated SDK won’t retry failed requests to that endpoint, regardless of the SDK’s user custom configuration.
