Test card numbers only work in a separate development environment. They are not valid on the public link of a production organization, nor inside your account’s Test environment — Cord Payments cannot be connected there by design, so card payments remain the one piece of the flow you can’t simulate yourself from within the app.

Request development access

Contact support to obtain an isolated environment and the current scenario matrix. There you can simulate approval, additional authentication, and declines without moving money or mixing records with production.

Never paste full card numbers into tickets, chats, quote notes, or Cord fields.
