How do I test Express Checkout - Braintree Direct?
Follow the instructions on the PayPal Developer Portal to complete your Braintree Direct integration. The Developer Dashboard allows you to create Braintree Direct SDK Sandbox credentials, which creates a Braintree account using your Business Facilitator account. Test transactions that are run via the Braintree Direct SDK using Sandbox credentials are displayed in the PayPal Sandbox if you log in to your Sandbox Business Facilitator account.
Note: The Braintree SDK (formerly v.zero SDK) credential is referred to as an “Access Token.” This is different from the credentials that a Braintree account user sees (also known as “API Keys”).
