Hi Klaviyo Team,

I’ve come across what appears to be an inconsistency in the API documentation for the /api/segments 

endpoint (revision: 2025-04-15).

In the documentation, there's an example that includes:

https://a.klaviyo.com/api/segments?fieldslflow]=name,status,archived&fieldslsegment]=definition,name

However, this request results in the following error:

'flow' is not an allowed field family for this resource. Allowed field families are segment, profile, tag, flow-trigger.

From what I understand, the /segments endpoint does not support include=flow, and thus fieldslflow]=... should not be applicable. The only valid include values for this endpoint appear to be tags and flow-triggers, which aligns with the error 

If i use this below it works.
https://a.klaviyo.com/api/segments?fieldseflow-triggers]=name,status,archived&fieldsesegment]=definition,name

If this is indeed an error in the docs, I wanted to flag it for correction — it can cause confusion when implementing based on that example. Thanks for all the work you do to keep the docs and API ecosystem solid!

Thanks,
Mayank
