I am a PHPer.  I am migrating the API from V1 to V2.

Can we use 

https://accounts.zoho.com/apiauthtoken/nb/create?COPE=ZohoCRM/crmapi&EMAIL_ID='.$email.'&PASSWORD='.$password.'&DISPLAY_NAME=SGCRM'

to generate a token to request the V2 APIs?

Because I found that I can also request V2 APIs by putting this token to the header( Authorization) now.

Thank you.
