Restrict results to Affiliation

[cgb37]

Hello, I am able to get the example app to work. However, our library needs a results page that returns the 25 most recent publications that are affiliated with our university. I have tried the following:

Taken from: https://dev.elsevier.com/sc_affil_search_tips.html
If I use the following url then I get an invalid api key
https://api.elsevier.com/content/search/affiliation?apiKey=myapikey&query=AFFIL%28Rosenstiel+School+of+Marine+and+Atmospheric+Science%29

If I use the following url in a browser, it will return results that contain our affiliation along with others, but we want to restrict it to our affiliation only. I have not been able to create this search url in the example app.
https://api.elsevier.com/content/search/scopus?apiKey=myapikey&sort=orig-load-date&query=affil%28Rosenstiel+School+of+Marine+and+Atmospheric+Science%29

Can you please provide an example code that returns the most recent 25 publications from a specific affiliation?
