title: GA3 Event Push Neccesary fields in Request
body: <p>I am trying to push a event towards GA3, mimicking an event done by a browser towards GA. From this Event I want to fill Custom Dimensions(visibile in the user explorer and relate them to a GA ID which has visited the website earlier). Could this be done without influencing website data too much? I want to enrich someone's data from an external source.</p>
  <p>So far I cant seem to find the minimum fields which has to be in the event call for this to work. Ive got these so far:</p>
  <pre><code>v=1&amp;
  _v=j96d&amp;
  a=1620641575&amp;
  t=event&amp;
  _s=1&amp;
  sd=24-bit&amp;
  sr=2560x1440&amp;
  vp=510x1287&amp;
  je=0&amp;_u=QACAAEAB~&amp;
  jid=&amp;
  gjid=&amp;
  _u=QACAAEAB~&amp;
  cid=GAID&amp;
  tid=UA-x&amp;
  _gid=GAID&amp;
  gtm=gtm&amp;
  z=355736517&amp;
  uip=1.2.3.4&amp;
  ea=x&amp;
  el=x&amp;
  ec=x&amp;
  ni=1&amp;
  cd1=GAID&amp;
  cd2=Companyx&amp;
  dl=https%3A%2F%2Fexample.nl%2F&amp;
  ul=nl-nl&amp;
  de=UTF-8&amp;
  dt=example&amp;
  cd3=CEO
  </code></pre>
  <p>So far the Custom dimension fields dont get overwritten with new values. Who knows which is missing or can share a list of neccesary fields and example values?</p>
