API Testing Mode automatically cancels all orders submitted through the API. Use it while developing or validating your integration so you can inspect requests safely without sending real mail.

​
What Testing Mode Does

  • Accepts API orders normally so you can validate your payloads and workflow.
  • Automatically cancels those orders instead of mailing them.
  • Prevents accidental production sends during development.
If testing mode is off, you have one hour to cancel an order manually before it moves further into fulfillment.

​
When to Use It

Keep testing mode enabled until you have verified:
  • Authentication is working
  • Your recipient payloads are correct
  • Your creative and message fields render as expected
  • Your application is ready to send production mail intentionally

​
How to Enable It

Visit API Settings and turn on API/Zapier Test Mode. Before going live, return to the same page and disable testing mode so real orders can be fulfilled.
