Upgrade guide

The Payments API is backwards-compatible with our previous payments API.

Migrate from the previous payments API to the new version as follows:

  1. Review the Payments API documentation.
  2. On your existing sandbox integration, switch from the old sandbox endpoints to the new endpoints.
  3. Run regression tests to confirm that there are no breaking changes.
  4. On your existing live integration, switch from the old live endpoints to the new endpoints.
  5. Contact support and request access to the new payment methods that you want to use.
  6. Update your integration to add support for the new payment methods.
  7. Test and go live.
