Cancel a scheduled reply

POST

https://api.plusvibe.ai/api/v1/unibox/emails/cancel-scheduled

Cancels a reply that was scheduled with POST /unibox/emails/reply + scheduled_at, so it is never sent. Works until the reply starts sending (then 400); a reply that was already sent or does not belong to the workspace returns 404. The pending item disappears from the Scheduled folder (GET /unibox/emails?is_scheduled=1) and a new reply can be scheduled on the conversation.
