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 endpoint allows you to delete the cancellation/pause of a scheduled send.
Scheduled sends cancelled less than 10 minutes before the scheduled time are not guaranteed to be cancelled.

The on-behalf-of header allows you to make API calls from a parent account on behalf of the parent's Subusers or customer accounts. You will use the parent account's API key when using this header. When making a call on behalf of a customer account, the property value should be "account-id" followed by the customer account's ID (e.g., on-behalf-of: account-id <account-id>). When making a call on behalf of a Subuser, the property value should be the Subuser's username (e.g., on-behalf-of: <subuser-username>). See On Behalf Of for more information.
