API Quickstart

What do I need to start building a direct API Integration?

Use our API to integrate Clearpay with any system or custom platform.

  1. Get Sandbox Credentials
  2. Speak to your Clearpay account manager to coordinate the receipt of your Sandbox credentials. These will enable you to commence the development and testing of your connection to our Sandbox environment.

  3. Choose Your Preferred Payment Flow
  4. Clearpay can either take payment as soon as the purchase is completed on your site, or defer the payment until a later date, depending on your business model. Review the documentation for more details on using direct capture (immediate payment flow) and using deferred payment flow.

  5. Start Testing
  6. Download our postman collection or use our API explorer to start testing the Clearpay calls before integrating with your systems.
