[Authorization - Sage X3]

and which customer region should I use? Or where I can find list of regions?

[Authorization - Sage X3]

Hello,
I registered my account, company, application and api.
I have clientId, clientSecret.

Where can I find my company's url (I need this to my scope as a value for 'customer=') and state value?

I'm trying to use auth url: https://api.qa-sagex3.com/v1/token/authorise
and access token url: https://api.qa-sagex3.com/v1/token/

Until now - without success.
Can anyone help me? 

Purpose:
I'm not able to receive access token for the first time.
I need it for api test, preferred somekind of demo environment with demo data.

Thanks!
