# Update Scheduled Mass Message (/api-reference/fansly/mass-messaging/update-scheduled-mass-message)

Edit a pending scheduled broadcast. Fansly replaces the message on edit, so send the complete desired state — `text` and `scheduledFor`. Pass the existing `scheduledFor` (from the List Scheduled Mass Messages endpoint) to keep the schedule time unchanged.
