Testing on a single device is super simple. When integrating the OpenBack SDK, set up a Custom Segment to be used as a unique identifier. The steps for setting up a Custom Segment can be found here for Android and here for iOS. To keep it simple, set the Custom Segment 1 to be a user's email address.
Now that you've set up the Custom Segment on the app side, you need to set it up on the dashboard. The steps to do so can be found here. For this simple test, create a Custom Segment with the following fields:
- Label - User Email
- Operator Type - String
- Default Operator - Equals
- Default Value - This can be any value, just use `user_email` for simplicity
Now just create a simple message and set your email address to be the value for your new Custom Segment.
