How to get shopify email data from some api?

[zhuliupiaoxue_1]

How do I get the data of the marketing campaign module, why does my Shopify backend marketing module have data, but I request the marketing events api but return an empty list

Seeing similar behavior both in test app and at other stores - empty response for marketing events read.

Any reason for that ?

Also getting Internal error response on GQL call

Can this be API scopes access issue ? Added “read_marketing_events” API scope
