| Parameter | Purpose |
|---|---|
msdynmkt_signaluserauthid |
The contact or lead GUID — the "who" of the signal. This is the field Customer Insights — Journeys uses to resolve the audience record. |
msdynmkt_profileid |
Also the contact or lead GUID. Used by the journey to pass per-contact context to downstream actions (Power Automate flows, branching conditions). |
msdynmkt_signaltimestamp |
When the event actually happened, in UTC. This is what ends up in interaction reporting. |
msdynmkt_signalingestiontimestamp |
When the signal was ingested into the platform, in UTC. Usually DateTime.UtcNow at the moment of the call. |
msdynmkt_bindingid |
Optional but important. Binds this trigger to a specific instance of a journey. Without it, the trigger acts on every journey instance the contact is currently in. |
