I am encountering an issue with the Amplitude API where I have noticed that some events contain segmentation data that is not present in the event list. Specifically, when querying the event list with the following Axios query:

{ url: "events/list", }

the event with the ID '56773164' is not included in the result. However, when querying the segmentation data with the following Axios query:

{ url: "events/segmentation", params: { e: { event_type: "_all", group_by: [ { type: "user", value: "event_type", }, ], }, start: "20230320T00", end: "20230320T00", m: "uniques", limit: 1000, }, }

the ID of the event can be found under seriesLabels in the response. What could be the cause of this discrepancy?

@DPA is looks like the support team sent you an email on May 6th. Do you mind checking your spam folder as well?

Hello Ester, 

Thanks for the confirmation. 
I checked the mailbox and also the spam folder.
However, I cannot find any received email on that day.  
Would you mind sending it again to my email?

Thank you. 


@DPA yes, asking the team to resend! The message came from @Jacenda Davis if you don’t mind checking your inbox and spam folder again. 🙏
