  title: HHAeXchange FHIR Configuration Internal API
  description: '## APIs


    **Internal (Provider)** — Returns base URL, provider and user details, environment, and validation in one call. Use when you need to resolve provider context for a client.


    **Internal (Generic References)** — Returns generic reference data from HHA database by CompanyID and ReferenceType. Use when you need to fetch reference codes and values for a specific provider and reference category.


    **Internal (Payer)** — Validates ClientId and XApiKey and returns payer context for **FhirAggregator** or **FhirPayer** clients (first active ClientMappings row by lowest Id). **FhirProvider** clients receive **400** with **ProviderTaxId is required** (use Internal Provider). **PayerId** and **Validation.PayerID** are **AgencyId**. BaseUrl is always null.


    **Onboarding API** — Create, Read, Update, and Migrate FHIR clients. Manages client configuration, agency mappings, and API keys.


    **Configuration (Rate limits)** — Read per-client/agency/env rate limit configuration.


    ## Authentication


    **OAuth2 (Bearer)** — Obtain an access token using the client credentials flow from the token endpoint. Send it in the request header as `Authorization: Bearer <token>`. API Gateway validates the token before the request reaches the API.
