Control the run

Wait for event

Pauses the run until a matching event arrives, then continues with its data.

Nodes › LogicOpen in Neblex

Good for: Asynchronous confirmations
Role: Works on the records in a flow
Find it in: Nodes › Logic

When to use it

A partner confirms later, such as a payment or shipment callback.
A long process must resume when an outside step completes.

Reach for something else when

Wait for formWhen the run is waiting for a person.WaitWhen a fixed delay is enough.

Example

Request a shipment label, then wait for the carrier's event keyed by the order id before notifying the customer.

How it works

Settings: Correlation key: a fixed value or one taken from the data, such as the order id.
Output: The delivered event's JSON body.
Delivering the event: While a run is waiting here, the step on the canvas shows the delivery call and a Send event now button. Delivery is an authenticated workspace request: it needs a signed-in member with permission to run flows. It resumes every run waiting on that key.

Drag from the previous step's output handle to its input, then open its settings with ✎ Edit.
Run the flow and click the step to see the records it received and produced.
