OneLink™ overview

At a glance: Many app owners have owned media assets such as websites, banners, social media posts, user emails, and telephone numbers. OneLink is a single link technology that converts owned media users into mobile app users, regardless of device, operating system, channel, or platform.  

About OneLink

  • Helps marketers engage their users by providing links that work across all owned media marketing channels. 
  • Redirects users to the correct app store (e.g. App Store or Google Play), landing page, or app (if users already have the app installed).

OneLink API

AppsFlyer lets you easily create OneLinks for any campaign that you want to run. However, sometimes you want to scale and run multiple campaigns at once, or run campaigns that comprise thousands of ads and creatives. 

Instead of manually creating every single OneLink for every campaign or ad creative, you can use OneLink API. OneLink API allows you to create thousands of OneLinks quickly and easily, saving you time and effort, and letting focus on your campaign and marketing efforts instead.

See the OneLink API guide to learn more.
