Create an A/B test group for a one-time send

​

Create a new A/B test group for a one-time send (referred to as a "newsletter" in our APIs). This duplicates the existing one-time send's content into a new test group, allowing you to test different versions of your message.

This endpoint does not require a request body. The new test group is created as a copy of the existing content.

You cannot add test groups to a one-time send that has already been sent.

Path Parameters
  • newsletter_id
    Type: integer
    required

    The identifier of a one-time send.

Body
application/json
Empty object
Responses
  • application/json
  • 400

    The one-time send has already been sent. You cannot add test groups to a sent one-time send.

  • 404

    The one-time send does not exist.
