The new version of Frames was released on July 12 2019. If you'd like to upgrade from the old version, simply follow our migration guide. If you need access to the legacy documentation, please contact our support team.

How it works

  1. You embed the Frames payment form in your website. The customer then enters their payment details directly on your checkout page.

  2. From Frames, your customer's sensitive information is processed by us and exchanged for a token. This process is called tokenization - tokenization - The industry standard process for protecting sensitive data by replacing it with an algorithmically generated number called a token. At we use tokenization to protect our customers' confidential payment information from fraudsters. Payment information is substituted with randomly generated numbers — the tokens — and passed to us over the internet. Using the token, we can locate the payment details from our secure vault and complete the request without the need to transfer any sensitive data. . Once you have the card token, you're ready to make the payment request.
