title: Branch.io deep link webhook: event contents between test and live mode are different
body: <p>I am trying to add referral functionality using branch.io deep link with a web hook. So, I’ve created the web hook by following the documentation (<a href="https://docs.branch.io/apps/deep-linking-api/#webhook-create" rel="nofollow noreferrer">https://docs.branch.io/apps/deep-linking-api/#webhook-create</a>) and set up the server to listen branch events. Everything was OK until testing in a production context.</p>
  
  <p>Indeed, my problem is that branch sends shorter events in live mode than in test mode. Above, you can see a sample event triggered in debug and then the same event triggered in release.</p>

  <p>Event in live mode</p>
  
  <pre><code>{ 
      metadata: { some metadata},
      os: 'Android',
      identity: 'new user identity',
      google_advertising_id: 'google id',
      os_version: '28',
      event: 'test_sign-up',
      event_timestamp: '2019-11-26T11:33:24.321Z',
      hardware_id: 'google id',
      ad_tracking_enabled: 'true' 
  }
  </code></pre>
  
  <p>So, my question is, how can I have at least the “session_referring_identity” field in live mode?</p>
  
  <p>For information, events are sent from a native Android application and links are test links for test mode and live links for live mode. Furthermore, the referral link contains the identity of the referrer, e.g. if I use the REST API, I can retrieve the identity of the user which has generated the deep link.</p>
  
  <p>Thanks in advance.</p>
