Is there a standard for the identifier within the d-tag or is it just some unique string?
Discussion
Any unique string. Just remember that the d-Tag cannot be changed when the user updates the listing. Otherwise it would create a new one.
Also, how are you generating the event ID? It does not match the one I generate 🤔
I am expecting event ID: 361174298e1bb4d5cc49edbc51123fef4835286953e7654ce8f1239e39dbea64 for the event below:
