  title: Twilio SendGrid Scheduled Sends API
  summary: The Twilio SendGrid Scheduled Sends API allows you to cancel or pause the
    send of one or more emails using a batch ID.
  description: 'The Twilio SendGrid 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 requests associated with a batch ID up
    to 10 minutes before the scheduled send time.


    See [**Canceling a Scheduled Send**](https://docs.sendgrid.com/for-developers/sending-email/stopping-a-scheduled-send)
    for a guide on creating a `batch_id`, assigning it to a scheduled send, and modifying
    the send.


    See the Mail API''s batching operations 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.'

      description: '**This endpoint allows you to cancel or pause a scheduled send
        associated with a `batch_id`.**


        Passing this endpoint a `batch_id` and status will cancel or pause the scheduled
        send.


        Once a scheduled send is set to `pause` or `cancel` you must use the "Update
        a scheduled send" endpoint to change its status or the "Delete a cancellation
        or pause from a scheduled send" endpoint to remove the status. Passing a status
        change to a scheduled send that has already been paused or cancelled will
        result in a `400` level status code.


        If the maximum number of cancellations/pauses are added to a send, a `400`
        level status code will be returned.'
