Since I could not find any examples of this online, and had to figure it out, I wanted to share it online.<p>This React TypeScript project demonstrates a Braintree OAuth integration flow between two merchants. It showcases how Merchant A can obtain authorization from Merchant B to perform actions on their behalf using Braintree's OAuth and transaction APIs.<p>In this example, Merchant A provides this application to Merchant B, allowing them to:<p>Grant OAuth permissions to Merchant A<p>Allow access to customer payment methods<p>Enable facilitated transactions<p>The integration uses two main Braintree APIs:<p>Access Token API - For OAuth authentication<p>Transaction API - For creating Shared Vault Transactions<p>FEATURES<p>OAuth connection flow<p>Token management and storage<p>Shared vault transaction processing<p>Real-time transaction status updates<p>Error handling and user feedback<p>Hope this is helpful to someone!
