# iOS SDK

> Get set up with the iOS SDK for your checkout experience.

In this quick start guide, we will take you through the following steps.

1. [Create an API key](/guides/payments/ios/quick-start/key) which is needed to generate
   the signed JWT token in step 2.
2. [Set up a server-side SDK](/guides/payments/ios/quick-start/sdks) to generate a client
   token for authenticating to the API.
3. [Install the iOS SDK](/guides/payments/ios/quick-start/ios) which will handle the
   capture of the payment method details and process the payment.
4. [Process the transaction](/guides/payments/ios/quick-start/transact) and inspect the result.
