Information about the programmatic aspects of in-app messages.
Customize dismiss buttons on iOS
By default, there is a dismiss button on the top-left of the in-app message dialog. If you want to use your own image as this button, you can set it by making a call to setDismissButtonImageWithName or setDismissButtonImageWithImage.
Customize dismiss buttons on Android
Although in-app messages are created in the Dashboard, you can modify the appearance of the dismiss button programatically.
Add in-app message triggers on iOS and Unity
By default, all existing tagEvent calls can be used as display triggers for in-app messages. You can also add additional in-app display triggers that don't tag events.
