Accept Mobile SDK

The Accept Mobile SDK for iOS or Android enables you to build your payment app without worrying about card data passing through your server. You retain complete control of the user experience.

Obtaining a Public Client Key

When you send the payment data to Authorize.Net, you use a public client key to secure it.

To obtain a public client key:

Step 1. Log in to the Authorize.Net Merchant Interface using an administrator account.

Step 2. Navigate to Account > Settings > Security Settings > General Settings > Manage Public Client Key.

Step 3. In the section Create New Public Client Key, click Submit. Request and verify a PIN for security reasons to complete the public client key process. The client key is shown as a string.

Securing the Payment Data

Use the Accept Mobile SDK to dispatch the payment data and receive a secure payment nonce (one-time-use token). For sample code, see our GitHub page for either iOS or Android.

Using the Secure Payment Nonce

The secure payment nonce can be used anywhere in the Authorize.Net API in place of credit card data. See our API Reference for an example of a payment transaction.

Creating a Transaction Key

If you have not already done so, you must create an Authorize.Net transaction key. This key is used to create a transaction-specific signature at your server. The signature is cross-checked by Authorize.Net servers when a transaction request is received, ensuring that no transaction is initiated by the consumer without your approval.

NOTE: Ensure that your transaction key is stored securely on your merchant server. Never store it within your app code on the device. If the key is compromised, generate a new key.

To create a transaction key:

Step 1. In the Authorize.Net Merchant Interface, navigate to Account > Settings > Security Settings > General Security Settings > API Login and Transaction Key.

Step 2. Enter the answer to the secret question in the Secret Answer field.

Step 3. Click Submit.
