# Set up WhatsApp Business with Nango

> Register an OAuth app with WhatsApp Business and connect it to Nango

This guide shows you how to obtain your WhatsApp Business API credentials (access token) to connect your application with the WhatsApp Business API through Nango.

## Understanding WhatsApp Business Authentication

WhatsApp Business uses API key authentication with access tokens. The access token is a JWT or OAuth2 token that authorizes requests to the WhatsApp Business API.

## Generating Your Access Token

To generate an access token for WhatsApp Business:

<Steps>
  <Step title="Create a Facebook Developer Account">
    If you don't already have one, sign up for a [Facebook Developer account](https://developers.facebook.com/).
  </Step>

  <Step title="Create a WhatsApp Business App">
    Create a new app in the Facebook Developer Portal and add the WhatsApp product to your app.
  </Step>

  <Step title="Generate Access Token">
    Follow Facebook's guide to [generate an access token](https://developers.facebook.com/docs/whatsapp/solution-providers/get-started-for-solution-partners#get-access-token) for your WhatsApp Business app.
  </Step>

  <Step title="Configure in Nango">
    Once you have your access token:

    1. Go to the [Integrations](https://app.nango.dev/dev/integrations) page in Nango
    2. Select your WhatsApp Business integration
    3. Add your access token as the API key
  </Step>
</Steps>

<Note>
  For production use, you'll need to complete the WhatsApp Business API setup process, which may include business verification and phone number registration.
</Note>
