Waiting for callback form external system.

Task goes to node and "freezes" for getting callback from external system or another process.


URL API callback


Corezoid (copy) - URL for getting callback specifically in this node

Mandrill (copy) - URL for getting callback from Mandrill (specifically in this node)

Path to task ID - input field for parameter name from request body which is contain the task_id

To modify task you need to send request (POST) to the callback URL which is copied from node.




This option gives a possibility to modify tasks synchronously. This option is enabled by default.

If you update task from external system with request to Callback URL and the task isn't in the current node you'll get an error task_not_in_current_sync_callback_node.

If option Synchronous is disabled and the task isn't in the current node, the request will be successful.

Alert when there is tasks queue

Critical amount of tasks in the node.

Limit the time of the task in the node

It is required to specify limit so that applications do not hang in the node forever.
