> How to register a PayPal REST API app and connect its Client ID + Secret to Nora.

PayPal integrations let your agents create orders, capture payments, issue refunds, and inspect transactions. Nora uses the **Client Credentials** OAuth grant — `client_id` + `client_secret` swapped for an access token at `/v1/oauth2/token`.

## Where to apply for credentials

<Card title="PayPal Developer Dashboard" href="https://developer.paypal.com/dashboard/applications/sandbox" icon="dollar-sign" arrow>
  developer.paypal.com → Apps & Credentials
</Card>

<Steps>
  <Step title="Pick environment">
    Toggle between **Sandbox** and **Live** — develop with sandbox credentials, switch to live for production.
  </Step>

  <Step title="Create an app">Apps & Credentials → **Create App**. Name it (e.g. "Nora").</Step>

  <Step title="Copy Client ID + Secret">
    Both visible on the app's detail page. Treat the secret as a password.
  </Step>
</Steps>

## Connect in Nora

| Field         | Value                                           |
| ------------- | ----------------------------------------------- |
| Client ID     | The PayPal app's client ID                      |
| Client Secret | The PayPal app's client secret                  |
| Use Sandbox   | `true` for sandbox apps, blank/`false` for live |

Nora POSTs `grant_type=client_credentials` against `/v1/oauth2/token` (sandbox or live host) to verify.
