**Self-Hosted GKE Deployments:** When running the Portkey Gateway on GKE with [Workload Identity Federation](/self-hosting/hybrid-deployments/gcp#setting-up-iam-permission) enabled (`GCP_AUTH_MODE=workload`), the Gateway automatically acquires Vertex AI access tokens from the GCP metadata server. No manual `Authorization` header is needed.

The GSA bound to the Gateway's KSA must have the `roles/aiplatform.user` role. See the [GCP deployment guide](/self-hosting/hybrid-deployments/gcp#setting-up-iam-permission) for setup.
