How do you use /StopPoint/Search/{query} endpoint to find a stop point id from a station name?

Hello,

I’m doing a simple transit app where users will be able to view arrivals for every station in the selected line. How can you find the Stop Point id for every stop?

Thank you in advance.

P.S. Please note that I’m a junior developer and this is one of my first major projects. I already have the API key and Id.
