How tokenization works

Judopay will tokenize your customer’s credit/debit card information for you to use in future payments. Tokenization ensures that your customer’s card information is collected and stored in a secure PCI-DSS compliant manner, minimizing your PCI liability as no card information is stored on your backend. This frees up your time to focus on developing other areas of your app.

Tokens will be passed back to you in the form of a callback if you integrate using ‘Mobile and your server-side’ or ‘Web payments’. If you chose to integrate using ‘Mobile only’, the token will be stored directly on the customer’s device.

See Payments for more information on tokens and payment types. For more information on PCI, please see the PCI compliance guide provided by the PCI Security Standards Council.

Ensuring a successful integration: The Setup section contains all the information and actions you will need for a successful integration. By following these steps, your app will be secure and provide a frictionless experience for you and your customers.

Mobile and your server-side Standard method


Use our native SDKs which lets customer's save their card details in your mobile app and store the tokenized cards on your backend for future payments. There are 4 steps to this:

  1. Register card – Customer registers their card in your app.
  2. Response with tokenized card – Judopay will pass back the tokenized card information.
  3. Save tokenized card – You can then send these tokens to your backend.
  4. Token payment– Perform future payments using the stored token.

Judopay’s customizable UI comes with built-in checks and security features, including data and address verification, real-time error detection and 3D Secure for frictionless card data capture. Our SDKs are also fully loaded with mobile-specific fraud prevention tools and allows for alternative payment methods such as Apple Pay and Android Pay.

For this method, Judopay provides server SDKs for all repeat payments directly from your backend. You can also use our webhooks to notify your backend when a transaction has taken place. If you do not use either of the languages below you can build directly to our API.

Web payments


Integrate simple and secure card payments into your website or web app with web payments optimized for mobile screens. There are 6 steps to this:

  1. Web payment request – Call Judopay’s web payment services.
  2. Redirect response – Judopay will respond with your URL.
  3. Redirect to hosted payments page – You redirect your customer to the payment page.
  4. Complete payment – User enters in their card details.
  5. Complete response – Judopay responds with success or decline.
  6. Redirect to success or decline – Judopay redirects your customer to the outcome that is specified by you for success or failure.

If you are aiming to host web payments with an app, please note that redirects slow everything down. User interfaces that don’t match your app make your customers feel unsafe, thus lowering your conversion rate. Native apps offer customers an optimal checkout experience that is simple, frictionless and secure.
