Optum Real

In Tenklo (free signup), go to Integrations -> Configure New Integration -> Optum Real.

Go to Connections -> Add Test Connection -> Authorize, then pick the Environment (sandbox or production) and enter your Optum Real Client ID and Client Secret for that environment (see the connect guide below). Later, you'll let your users do the same directly from your app.

Optum Real's API surface is organized by product (Claim Status, Eligibility, Professional/Institutional Claims, etc.), each documented with its own endpoint path in that product's Technical Reference Guide. Once you know the path, call it through Tenklo's proxy — replace <product-endpoint-path> and the placeholders below with your Environment API key, integration ID, and connection ID:

Until TINs are associated, sandbox calls return mock data — you can also force mock responses at any time by sending the optional environment: sandbox request header on API calls.

curl "https://api.tenklo.dev/proxy/<product-endpoint-path>" \
  -H "Authorization: Bearer <NANGO-API-KEY>" \
  -H "Provider-Config-Key: <INTEGRATION-ID>" \
  -H "Connection-Id: <CONNECTION-ID>"

Or fetch credentials with the Node SDK or API.
