From tested to ready.

You can build your server adapter and exercise payment states now. Moving to real payments requires a separate launch process; a merchant approval or successful sandbox test does not activate processing.

  1. Complete your business application and respond to review requests.
  2. Agree on supported methods, markets, fees, settlement, refund and dispute terms.
  3. Wait for an approved production processing connection and the supported live integration contract.
  4. Validate payment verification, customer checkout, refunds, failure handling and fulfilment against that contract.
  5. Receive explicit activation before accepting real payments.

Tell the team about your platform and integration requirements through workspace support. Versioned documentation will describe any future live contract before it is enabled.
