[Content]: #2745
Description
What article on segment.com/docs is affected?
https://segment.com/docs/connections/destinations/catalog/actions-google-analytics-4/#custom-events
What part(s) of the article would you like to see updated?
https://segment.com/docs/connections/destinations/catalog/actions-google-analytics-4/#custom-events
GA4 rejects events with the pipe in the event name : | so event : "Home | Nav" would technically be silently dropped
This is to be expected, but should possibly be added to our docs and possibly taken into account for transforming events.
Limitations
Parameter names (including item parameters) must be 40 characters or fewer, may only contain alpha-numeric characters and underscores, and must start with an alphabetic character.
We have a note here that Google does not accept spaces so we remove spaces and snakecase: https://segment.com/docs/connections/destinations/catalog/actions-google-analytics-4/#custom-events. However, I didn’t include anything about special characters. We also link to the Event naming rules in the Google documentation. Do you think we need more than that? If so, could you file a docs PR to add more to that blue box and share here so I can review?
It might be beneficial for our customers to see a few examples of bad naming conventions to catch their eye? I definitely read that information/warning box but didn’t consider events with special characters as being potentially problematic.
Such as :
event : "Home | Profile" → will be rejected by GA4
event : "Home Profile" → will be accepted by GA4 and converted to Home_Profile
