How to Switch Scenario

Switch scenarios to simulate different responses (status, delay, error rate) for fast failure-mode testing.

1) Open your endpoint

From the dashboard, select the endpoint that has multiple scenarios attached.

2) Set Active Scenario

From ActionsSet Active Scenario, choose which scenario should be active. Only one can be active at a time.

Set Active Scenario modal with radio selection
Select the desired scenario; note Status, Delay and Error Rate shown for each.
Tip: Keep a default 200/0ms scenario and a throttling or outage scenario (e.g., 429/503 with delay and error rate) to test retries and backoff.

3) Confirm and test

Click Set Active. Calls to the endpoint now respect the selected scenario’s status, delay and error rate.
