Hello. I am new to the Sage API and have had lots of issues/confusion trying to get the authentication process to work. I created an app and applied the client id and secret to postman as specified in your getting started doc. After I entered my email and password to authenticate, I would get errors returned from your server but I have no idea what they are. I just see a page stating there was an error. I tried calling for help but that was completely useless as it would hang up after telling me to go online for help.
It seems like I need to create a trial account as well to get the authentication to work. If that is true, I am confused then why I needed to create my app in the first place.
Here is what I entered in postman.
I ended up getting this to work. Had to take a break and clear my head. Thanks
