# Optum Real

> Integrate your application with the Optum Real Medical APIs

## 🚀 Quickstart

Connect to Optum Real with Nango using your Client ID and Client Secret.

<Steps>
  <Step id="create-integration" title="Create the integration">
    In Nango ([free signup](https://app.nango.dev)), go to [Integrations](https://app.nango.dev/dev/integrations) -> *Configure New Integration* -> *Optum Real*.
  </Step>

  <Step id="authorize-optum-real" title="Authorize Optum Real">
    Go to [Connections](https://app.nango.dev/dev/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.
  </Step>

  <Step id="call-api" title="Call the Optum Real API">
    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 Nango's proxy — replace `<product-endpoint-path>` and the placeholders below with your [secret key](https://app.nango.dev/dev/environment-settings), [integration ID](https://app.nango.dev/dev/integrations), and [connection ID](https://app.nango.dev/dev/connections):

    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.

      <Tab title="cURL">
        ```bash theme={null}
        curl "https://api.nango.dev/proxy/<product-endpoint-path>" \
          -H "Authorization: Bearer <NANGO-SECRET-KEY>" \
          -H "Provider-Config-Key: <INTEGRATION-ID>" \
          -H "Connection-Id: <CONNECTION-ID>"
        ```
      </Tab>

      <Tab title="Node">
        Install Nango's backend SDK with `npm i @nangohq/node`. Then run:

        ```typescript theme={null}
        import { Nango } from '@nangohq/node';

        const nango = new Nango({ secretKey: '<NANGO-SECRET-KEY>' });

        const res = await nango.get({
            endpoint: '<product-endpoint-path>',
            providerConfigKey: '<INTEGRATION-ID>',
            connectionId: '<CONNECTION-ID>'
        });

        console.log(res.data);
        ```
      </Tab>
    </Tabs>

    Or fetch credentials with the [Node SDK](/docs/reference/sdks/node#get-a-connection-with-credentials) or [API](/docs/reference/api/connection/get).

    ✅ You're connected! Check the [Logs](https://app.nango.dev/dev/logs) tab in Nango to inspect requests.
  </Step>

  <Step id="implement-in-app" title="Implement Nango in your app">
    Follow our [Auth implementation guide](/docs/guides/primitives/auth) to integrate Nango in your app.

    To obtain your own credentials, follow the connect guide linked below.
