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

• Read the Eligibility requirements to determine whether your Express Checkout integration is a good candidate for the In-Context Checkout experience. If In-Context Checkout does not support a feature that you currently use, your buyers are presented with the Express Checkout full-page redirect checkout flow.
• Have a PayPal business or premier account.

Next

Enable In-Context Checkout.
