# Why Is the Campaign-Level Control Group Unavailable in Connector Campaigns?

> Campaign-level control groups aren't supported in connector campaigns. Use a Flow-level control group as a workaround for audience testing.

## Problem

Unable to use the campaign-level control group when creating connector campaigns.

## Solution

* MoEngage does not support campaign-level control groups for connector campaigns.
* However, you can work around this limitation by including the connector campaign in a Flow.

* In the Flow segmentation settings, you can set up the **Flow control group** for the entire flow.

* This **Flow control group** is applicable to the target audiences of the connector campaign.
