I have a custom event that is firing inconsistently, and appearing on some contacts’ timelines but not on others.
We use the HTTP API and we curl to the correct endpoint and we pass through the email of the user. The event is fired for anyone who completes our product signup process, and I have a number of contacts that I know for a fact have completed our signup flow, but have not fired the event.
What additional information do you need to get to the bottom of this? I have a number of contacts I can give as examples if need be.
