My API key doesn't work

[For h]

Hi everyone thank you for your time!

I'm really new to the MTA api so I don't know much

I'm trying to get data on when the next 2-3 trains are arriving to a specific station

so I opened the dev console in chrome when going to https://new.mta.info/ and check were they get the data from and I see that the URL

https://otp-mta-prod.camsys-apps.com/otp/routers/default/nearby?stops=MTASBWY%3AF30&apikey=

returns exactly what I need!!! a response like this

But when I try fetching the data with my api key that I got here https://api.mta.info/#/AccessKey

It returns {"message":"Invalid authentication credentials"}

So would anyone be able to help me out

Thank you so much and have a great day
