}🔴devicemagic_send_dispatch(device_identifier, form_namespace, payload, form_name, form_description, ...)
WRITE: pushes a form, optionally prefilled, to one device where its user will see it (like assigning a job). Not idempotent: calling it twice sends two dispatches. Needs the Enterprise plan. The form is named by its namespace (list_forms); `payload` maps question identifiers (get_form) to prefilled values (subforms = nested objects, repeat groups = arrays). POST /api/v2/devices/{identifier}/dispatches.json.

}🔴devicemagic_revoke_dispatch(device_identifier, dispatch_id, confirm)
WRITE: withdraws one outstanding dispatch from a device (the form disappears from the device). It cannot be undone, but the dispatch can be sent again. DELETE /api/v2/devices/{identifier}/dispatches/{id}.json.

WRITE: approves a device that is waiting for approval (pending_approval is true) so it can receive forms. Approving an approved device has no effect. POST /organizations/{org}/devices/{id}/approve.

"type": "object",
"properties": {
