REST API

`Flex API`

The Flex API enables merchants to securely accept customer payment information captured within a server-side application using a set of APIs. These APIs protect your customer's primary account number (PAN), card verification number (CVN), and other payment information by embedding it within a transient token. This allows payment data to be stored and transported and complies with the Payment Card Industry Data Security Standard (PCI DSS) policies and procedures. These transient tokens can be validated by the receiver to ensure the data integrity and protect against data injection attacks.

WARNING

Flex API is intended for server-side applications only. Do not use the Flex API in client-side applications. To add secure payments directly into client-side code, use Unified Checkout.

How It Works

Follow these steps to capture payments using the Flex API:

Establish a payment session with a predefined customer context.

Validate the JSON Web Token.

Populate the JSON Web Token with customer information.

Customer Context

An important benefit of the Flex API is managing Personal Identifiable Information (PII). You can set up your customer context to include all PII associated with transactions, protecting this information from third parties.
