Question

Working with CJA & AEP

Hello everyone, 

Good Morning. 

I have worked on Adobe reporting API previously and currently exploring the CJA API to extract data from Adobe workspaces 

I have created a project in console and adding CJA API to it and was able to establish a connection and can see data views via the /data/dataviews end point. 

However the subsequent calls via /data/dataviews/{dataview_id}/dimensions end point are failing with API error 403027 . The solution mentioned is to add AEP API into the project. 

Can some one explain me the dependency of AEP API for the same. Thanks in advance
