PUT /messages/{messageId}

When you sent the original message, this is the UUID that was returned in the call response. Use this ID to fetch, update or delete a message with the appropriate endpoints.

This is the mobile number you want to send your message to. Write Australian numbers in national format (e.g. 0412345678) and international numbers (paid plans only) in E.164 format (e.g. +441234567890).

Use a string for a single recipient, and an array of strings for multiple recipients, e.g. "to": ["0412345678", "+441234567890"]. If you're using the Free Trial, you can include up to 5 recipient numbers in the array. If you're using a paid plan, you can bulk send up to 500 messages at once.

Don't want to send the message right away? Tell us what time you want to add it to the queue for sending instead.

Set the time in London Greenwich Mean Time (adjusting for any time difference) and use ISO format, e.g. "2019-08-24T15:39:00Z".

You can schedule a message up to 10 days into the future. If you specify a timestamp outside of this limit, the API will return a FIELD_INVALID error.

If the message is queued or unable to reach the recipient's device, tell us how many minutes the network should keep trying. Use an integer between 10and 1440. If you don't set a value, we'll retry for 10 minutes.

Default value: 10
