# Preview runs of sequences

Before adding sequences to a timeline, preview them individually.

## Running a Preview

1. Ensure your desired **Data Item** is checked in the sequence header.

2. Select **AD User** credentials if applicable.

3. Choose the region (for example, North Europe or East US).

4. Click **Preview**.

Go displays live feedback:

* Execution progress per step
* Response times
* Error counts
* Validation results

Preview mode helps verify that all steps, variables, and data items behave as intended before being orchestrated into a Timeline.
