AppNexus technology powers the most innovative trading solutions and marketplaces for Internet advertising.


The only thing you’ll need in order to activate our AppNexus audience integration is your Member ID, which you can obtain from your AppNexus support representative. As an AppNexus Audience Integration, we utilize our own AppNexus account to synchronize audience data between our platforms, and share the synchronized audiences with your AppNexus account via the Sharing API.

User Identity Mapping

When forwarding audience data to AppNexus, mParticle will send IDFAs, Google Advertising IDs, MD5 and SHA-1 of Android Device IDs. If you have enabled a cookie sync integration with AppNexus, mParticle will also forward AppNexus User IDs for your Web users where available.

Upload Frequency

The AppNexus Integration uses Bulk Forwarding. Bulk Forwarding means that, instead of uploading updates to an audience in real time, mParticle compiles updates into a queue until either a given amount of time has passed since the last upload, or until a certain number of updates are waiting to be sent.

By default, mParticle uploads to AppNexus every five minutes.
