Setting a user id to allow integration with your CMS/CRM/backend

You can send the id you use to identify users on your backend. This will allow backend integrations for one to one messaging or based on segments created on your backend.

iOS

[XPush hitTag:@“user.external_id" withValue: YOURUSERSID]; 

Android

mPushConnector.hitTag("user.external_id", YOURUSERSID);

Website

xtremepush('set', 'external_id', YOURUSERSID);

IDs can be used later for targeting users in the segmentation engine or via API.
