Retrieve image from app into report

Hi all!

I am a non-developer and stuck with my current report! 

I am retrieving data from a mobile app that allows you to capture pictures. From the database I can see a "media link" which looks like a url but I can see it relates to an api as it has api. In the text. 

I know how to retriev an api key from the app for authentication, but that is it! 

anyone that can guide me on how to buld a report that pulls a specific image in based on an api-type url? 

thank you in advance
