I want to send some custom user data to an event (e.g. first name)
Right now I’m just setting the userId (setting it once, not on each event), so I do have an identifier for the event.
Is there a way to associate custom data with the userId, or should I send this data on every event?
Hey
Depending on how you are sending data ( via SDK or HTTP API), you can choose to send the user properties for a user_id along with every event or make a call to the Identify API to update the user properties.
