Hello,

I’m trying to get data via the Dashboard REST API and was able to successfully pull data via the event segmentation endpoint. However, for my next chart I need to use a group_by and use custom event propertie for grouping by. I have the following input parameters and and receive response with error:

As you can see from the screenshot, “click details” is a custom event I use and “isin” is an event propertie I’d like to use for group by. If I deactivate “g” parameter or switch value for it to “platform” the request works fine and I receive a proper answer. What do I do wrong with “group by”? I can tell for sure that “isin” event propertie is valid in my project and I can use it in amplitude web interface and receive a proper graph:
