# Retrieve all scheduled sends ## API Overview Using the Cancel Scheduled Sends API, you can cancel or pause sending one or more groups of emails. SendGrid defines these multiple scheduled send requests together as batches identified with a `batch_id`. With this API, you can perform the following tasks on scheduled emails: * Define and validate the ID for a batch of messages. * Retrieve, update, pause, resume, or cancel a scheduled send. Cancelling or pausing a batch of messages include the following conditions: * You can't pause or cancel more than 10 different batches at one time. * You can't pause or cancel a batch later than 10 minutes before the scheduled `send_at` time. * When you cancel or pause a batch, all messages associated with that batch stay in your sending queue. * When a cancelled batch reaches its `send_at` time, SendGrid discards the messages. * When a paused batch reaches its `send_at` time, SendGrid retains the messages. When you resume a paused batch, SendGrid delivers your scheduled send. * When a paused batch passes 72 hours after its `send_at` time, SendGrid discards the messages as *Expired*. To cancel a scheduled send of a single message, consult [Canceling a Scheduled Send][cancel-send].

If you have scheduled a send using the `/mail/send` endpoint and the `send_at` field but no `batch_id`, the send will be scheduled for delivery; however, it will not be returned by this endpoint. For this reason, you should assign a `batch_id` to any scheduled send you may need to pause or cancel in the future. ## Operation details ### Authentication API Key ### Headers ```json [{"in":"header","name":"Authorization","required":true,"default":"Bearer <>","schema":{"type":"string"}},{"name":"on-behalf-of","in":"header","description":"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.
