Get Started

The PayPal iOS SDK integration requires usage of both the client-side SDK and a server-side integration with PayPal's Orders v2 API. This section addresses the server-side integration process.

If you have already set-up your server environment, skip to the server setup instructions and make sure your server covers these functionalities.

Obtain API Authorization

The PayPal REST API uses the OAuth 2.0 protocol to authorize calls. Before you can make calls to the Orders v2 API, as needed by the Commerce Platform SDK, you must secure PayPal developer credentials. When you have completed this process, you will have secured the following credential elements:

• Sandbox app account
• Client ID and secret
• API access token

To generate REST API credentials for your sandbox environment:

1. with your PayPal account credentials. If you don't have an account, you can click on the sign up option.
2. On My Apps & Credentials, use the toggle to switch between live and sandbox testing apps.
   • Note: If you are creating a Sandbox app, you will also need to select a test business account that will act as the API caller. For more details, see Get Started.
   • 
3. Navigate to the REST API apps section and click Create App.
4. Type a name for your app and click Create App. The app details page opens and displays your credentials.
5. Copy and save the client ID and secret for your app (click Show to display the actual Secret value).
6. In the Sandbox App Settings section, open the Return URL form by clicking Show, then enter the universal link you set at the time you registered your app domain with Apple.
