Wait For Callback

The Wait for Callback node is used to facilitate an asynchronous process external to Chat Flow and continue the flow when a callback is received.

This node will block the flow until a callback is received or the session times out.

To use this node, the Wait For Callback API needs to be set up.

This node must be used in conjunction with the Set Variables node. The Reference that is being set is the variable from the Set Variable node.
