In-App Message Troubleshooting

What are the recommended image dimensions?

We show In-App messages based on the dimensions of the phone currently being displayed on. There are a few common aspect ratios for devices and resolutions (especially for Android) which could all affect the viewing of the In-App messages.

A 16:9 aspect ratio is the most common for devices, but 4:3 and 3:2 aspect ratios are close compromises.

Can I create an In-App via the API?

Currently all In-App messages need to be created through the OneSignal dashboard.

On each page of your app, you can set our addTrigger method and through your own API requests to your app, feed in the trigger key:value set within the dashboard to trigger the IAM based on your own network requests.

I've update my In-App, when do In-App changes take effect?

Once you update an In-App messages from the dashboard. The changes will go into effect immediately and end-users will see the updated message after the app has been closed for 30 seconds before re-opened.

The WYSIWYG preview is very close to what your users will actually see. However, devices have a range of screen dimensions and so we have an easy-to-use preview on device option that will send the in-app message to any test device you'd like immediately to take a look at it on your own phone.
