Cancel or pause a scheduled send

POST {{baseUrl}}/user/scheduled_sends

This endpoint allows you to cancel or pause an email that has been scheduled to be sent.

If the maximum number of cancellations/pauses are added, HTTP 400 will be returned.

The Cancel Scheduled Sends feature allows the customer to cancel a scheduled send based on a Batch ID included in the SMTPAPI header. Scheduled sends cancelled less than 10 minutes before the scheduled time are not guaranteed to be cancelled.
