Delete a one-time send

​

Deletes an individual one-time send (referred to as a "newsletter" in our APIs), including content, settings, and metrics. It will be removed from segments, and its templates will no longer show in the Message Library.

If it's an in-app message, this cancels any undelivered, in-app message, too.

    required

    The identifier of a one-time send.

Responses
  • 204
