REST API

Upload Your Encryption Key

Payment information can be retrieved from the Unified Checkout platform by invoking the Payment Credentials API. This API retrieves all of the data captured by Unified Checkout. This information is transmitted in an encrypted format to ensure the security of the payment information while in transit.

You must generate a encryption key pair to retrieve this encrypted payment information and the public encryption key must uploaded to the Unified Checkout system.
