Prerequisites

Important: Integration with checkout.js V3.5 is Deprecated. For the latest integration information, see the PayPal Express Checkout Integration Guide.

To integrate the Express Checkout with In-Context flow, you must:

  1. Have a PayPal business or premier account.

  2. Get an access token.

    In exchange for these credentials, the PayPal authorization server issues access tokens called bearer tokens that you use for authorization when you make REST API requests. A bearer token enables you to complete actions on behalf of, and with the approval of, the resource owner.
