+### Request timeouts
+
+Pass-through routes default to a **600 second** upstream timeout. Set `general_settings.pass_through_request_timeout` for a global override, or `timeout` on a custom endpoint (per-endpoint wins). Applies to custom pass-through endpoints and native provider passthrough routes (e.g. Bedrock `/converse`).

 ### Header Options
 - **Authorization**: Authentication for the target API
 - **content-type**: Request body format specification
