The Cancel Scheduled Sends API allows you to cancel or pause the send of one or more emails using a batch ID.
A batch_id groups multiple scheduled mail/send requests together with the same ID. You can cancel or pause all of the mail/send requests associated with a batch ID up to 10 minutes before the scheduled send time by passing a batch_id to the "Cancel or pause a scheduled send" endpoint.
For a guide on creating a batch_id, assigning it to a scheduled send, and modifying the send, see "Canceling a Scheduled Send".
The Cancel Scheduled Sends API also make it possible to validate a batch_id and retrieve all scheduled sends as an array.
When a batch is canceled, all messages associated with that batch will stay in your sending queue. When their send_at value is reached, they will be discarded.
When a batch is paused, all messages associated with that batch will stay in your sending queue, even after their send_at value has passed. This means you can remove a pause status, and your scheduled send will be delivered once the pause is removed. Any messages left with a pause status that are more than 72 hours old will be discarded as Expired.
This operation allows you to validate a mail batch ID.
If you provide a valid batch ID, this operation will return a 200 status code and the batch ID itself.
If you provide an invalid batch ID, you will receive a 400 level status code and an error message.
A batch ID does not need to be assigned to a send to be considered valid. A successful response means only that the batch ID has been created, but it does not indicate that the ID has been assigned to a send.
