# Run Event in Journey

The Run Event in Journey Data Operation allows Data Flows to run Session Events within a user’s session or invoke an Event in a different session. This is useful for performing client side operations (such as updating a web page, sending a text message, placing a phone call, etc.) from within a Data Operation.&#x20;

## Use Cases

* Update a user’s Web Flow based on an update from another system by passing in the session ID from a stored value

## Data Operation Properties

### Session ID

Expects type `text`.

Session ID corresponding to the session where the Session Event will be run.

### Journey Event

Dropdown of all existing Session Events in the App to select the one to run.

## Run Results

This allows the running of this specific Session Event to check the parameters have been correctly set. A [Variable](../../working-with-data/working-with-data-overview/variable-namespaces) is automatically created to hold the results of this Data Operation. This will be an object describing the result of the operation.
