The relay proxies the upstream response — when the upstream returns a 3xx with a `Location` header, the relay forwards that redirect (typically back to the application UI). JSON or text bodies are forwarded with the upstream status. ## OpenAPI ````yaml /api-reference/openapi.yaml get /api/google-sheets/oauth/google/callback openapi: 3.0.3 info: title: Tether Relay and Tether API version: 1.0.0 description: >- Route-derived OpenAPI contract generated from tether-relay backend sources.
