How do I send links in push to my mobile app? has integrated the OneSignal SDK in a smart way where they leverage deep linking instead of the pop-up browser OneSignal provides by default.

When you send push to mobile app users, do not use the "Launch URL" field. Instead use the "Additional Data" field or data parameter from our REST API. The Key should be targetUrl (the "U" is capitalized) and the Value should be the url to the page you want to send users:

If you send to web and mobile at the same time, in the "Launch URL" area select "Different URL for web/app" and leave the "APP URL" blank.
