Proxy
Why proxy exists
Section titled “Why proxy exists”Raw responses from sources like the U.S. Census geocoder can be wide, nested, and awkward for declarative Flow. Proxy paths normalize selected responses into predictable buckets—collections you can loop in Flow, plus shortcuts when you only need the top match.
Behavior
Section titled “Behavior”- GET-only routing with optional host allowlists
- Errors return JSON with a clear status—not HTML error pages
- Field names align with the proxy service’s OpenAPI spec
Import the proxy service schema separately from lookup services when wiring External Services.
