WhatsApp Business OAuth 2.0 connector profile – StackOne setup guide

Go to Meta for Developers and sign in.

• Click Create App.
• Enter an App name (e.g., “StackOne WhatsApp Integration”) and an App contact email.
• Click Next.

On the Add use cases screen:

• Select Connect with customers through WhatsApp and click Next.
• Also select Measure ad performance data with Marketing API — this enables Marketing API access and is required for the business_management permission used by business user and system user endpoints.
• You may also select any other use cases relevant to your app — additional use cases can be added now or later from your App Dashboard.
• Note: The use cases you select here determine which permissions (scopes) are available during the OAuth flow. These map to the OAuth scopes you configure in this connector’s Scopes field and should be provided there as a comma-separated list (e.g., whatsapp_business_messaging,whatsapp_business_management,business_management).

Meta will prompt you to link a Business Portfolio:

• Select the Business Portfolio linked to your WhatsApp Business Account.
• Click Create app.
• If no portfolio appears, go to Meta Business Suite, create a Business Portfolio, and ensure you have Business Admin access.

In your App Dashboard left sidebar:

• Scroll down the left sidebar to find the Facebook Login for Business section.
• Click on it to expand and select Settings.

On the Settings page:

• Under Valid OAuth Redirect URIs, add https://api.stackone.com/connect/oauth2/whatsapp-business/callback.
• Click Save changes.

In your App Dashboard, click App settings in the left sidebar and select Basic.

On the Basic Settings page:

• Copy the App ID — this is your Client ID.
• Click Show next to App Secret, verify your identity if prompted, then copy the value — this is your Client Secret.
• Store the App Secret securely and never expose it publicly.
