Creates a Reminder. Use the request body to set parameter values including the Reminder name, message, schedule, and recipients.The resource is the entity the Reminder should be linked to. This can be a Drawer (sidedrawer/sidedrawerId), Folder (sidedrawer/sidedrawerId/record/recordId), or Plan Request (sidedrawer/sidedrawerId/plan-request/planRequestId). The schedule entity includes the start date and an optional recurrent entity that describes when the Reminder should repeat. The to entity accepts both OpenIDs and emails, so you can send Reminders to people internally or externally.
