How to capture ECID in an Adobe Tags data element

Rule action: read and store ECID

alloy("getIdentity").then(function (result) {
  if (result && result.identity && result.identity.ECID) {
    _satellite.setVar("ECID", result.identity.ECID);
  }
});

Data element: custom code

return _satellite.getVar("ECID");

Use it anywhere as %ECID%.

Validate

• _satellite.setDebug(true) to enable Tags debugging
• _satellite.getVar("ECID") in the console
• Check the identity section of the Edge request in the AEP Debugger

Timing matters

ECID is available only after the identity call resolves. Rules that need it should run after the rule that stores it, or wait for a custom event.
