Overview

Flex Microform is Smartpay Fuse’s hosted field solution that allows you to securely tokenize card data for immediate and future payments. When a customer submits their card details, the information is replaced by a card token to use for API requests instead of the actual card number.
When Flex Microform is integrated in your system:
  • Server-side request
    : Your server sends a request to Smartpay Fuse. This creates a time limited, signed JWT (the “capture context”) that encodes key parameters of the transaction, including transaction details, target origin and one-time use public keys. You can safely pass this JWT to your front-end application.
  • Client-side implementation
    : Embed the Flex Microform JavaScript library in your page and initialise it with the “capture context” generated by your server-side request. The library renders the necessary iFrames within designated containers on your page. When the customer submits the form, the library generates a PCI-compliant transient token representing the cardholder details, which is valid for 15 minutes.
  • Validate and use the transient token
    : Use this transient token in your service to make API calls and progress the transaction.
