# Update an SMS activity

PUT https://api.close.com/api/v1/activity/sms/{id}/
Content-Type: application/json

This can be used to modify a draft or send it once the draft is complete.

To send an SMS immediately, you can update its `status` to `outbox`. To send it at a later time, change the `status` to `scheduled` and provide the desired date & time in the `date_scheduled` field.
