Mobile App SDKs

Easily integrate native, in-app mobile payments right into your Android or iOS app by using the Amazon Payment Services mobile SDK.

When you integrate in-app payment processing your customers no longer need to follow the time-consuming and complex route of redirection to a mobile browser to pay.

Our pre-packaged SDKs require less development effort and skills compared to custom-coding your own in-app payment experience.

Using our Android and iOS SDKs you can deliver a seamless in-app checkout experience, minimizing the chance that your customer abandons a purchase before completion.

Mobile App SDK Features

Native in-app payment. In the past, customers that made a purchase in your app would be redirected to a mobile browsing session to complete payment. It is an inconvenient experience for customers, and customers can lose trust, abandoning the purchase. Instead, the mobile app SDK ensures that your customer completes the entire transaction in-app.

Fully secure. Your customers enjoy the same, trusted Amazon Payment Services experience in-app when you make use of the mobile app SDK. Card details are transmitted across a fully secure layer and authentication is securely handled by Amazon Payment Services.

Fully customized. The Amazon Payment Services mobile SDK is fully customizable, giving your customers a native experience on both Android and iOS devices.

When should you use the mobile app SDK?

If your business has an Android or iOS app that your customers use to buy goods or services we will almost always recommend that you choose to integrate payment processing by accepting in-app payments.

A faster route to enabling in-app payments is to use our mobile app SDK which delivers a much better customer experience in comparison to redirecting customers to a mobile browser for payment. While redirecting to a mobile browser was a common practice in the past, most users now expect a purchase experience that is native and fully contained within your app.

Our mobile app SDK offers a faster alternative compared to writing custom code by delivering the essential payment processing code you need in a single package. However, if you have enough development resources you should consider custom-coding your in-app payment experience by directly tapping the Amazon Payment Services APIs.

Mobile SDK integration workflow

Every time your customer initiates an in-app payment your app sends a request to the Amazon Payment Services server for a new authentication token to authenticate the use of the SDK. The remainder of the payment process is roughly similar to our other integration routes.

This is the workflow when you use the mobile SDK integration:

  1. Your application initiates the Amazon Payment Services mobile SDK and passes the relevant parameters to the Amazon Payment Services mobile SDK.

  2. The Amazon Payment Services mobile SDK starts a secure connection and sends the received parameters to the Amazon Payment Services API to be validated.

  3. Amazon Payment Services returns the validation response.

  4. Next, the mobile SDK submits the cardholder's data to the Amazon Payment Services API to process the order.

  5. The API validates and processes the order with the customer's bank.

  6. The API returns the Amazon Payment Services response to the SDK.

  7. In turn, the mobile SDK returns the Amazon Payment Services response to the corresponding callback method.

Optionally, your mobile interaction with the Amazon Payment Services server can also be configured to include direct communication with your server.

The integration process is slightly different for Android and for iOS. See more details about the Amazon Payment Services Android SDK integration or read up on iOS SDK integration.

API authentication tokens for the Mobile SDK

A unique mobile SDK authentication token is required for every request sent to the SDK. You use the mobile SDK authentication token every time you process a payment operation through the mobile SDK.

Note that a unique authentication token must be created for each transaction. Each authentication token has a limited lifespan of just one hour. The authentication token will expire after an hour if no new request is sent from the same device.

👆 Creating and initiating a mobile SDK authentication token is the responsibility of your app.
