The Nuvera REST API provides partner organizations with server-to-server access to customers, beneficiaries, documents, payment reference data, payments, screening reads, and support workflows. Only partner organizations can use the REST API layer. Customer-platform users do not receive API applications or API keys. Nuvera admins can manage partner API applications only for support, emergency disablement, permission correction, and partner-assisted key rotation.

Authentication

Every REST request must include both headers: 
x-api-key: <your-api-key>
Authorization: Bearer <signed-request-jwt>
The API key identifies the API application. The signed JWT proves possession of the partner-held RSA private key and binds the request method, exact path and query string, short expiration, replay nonce, and request body hash. Endpoint security schemes are generated from the Nest REST decorators when the API dev server starts. Do not hand-edit docs/api-reference/openapi.json; use the guide pages for human signing and rotation instructions, and use the generated endpoint pages for request and response schemas.
