Hi duyanhth,
Thanks for reaching out, As you already have a Developer account with us you are currently able to access AccountRight and New Essentials v2 via the API.
When completing Authentication for AccountRight we want to make sure we use the scope of `CompanyFile` or `CompanyFile la.global`
scope:
`CompanyFile` = AccountRight, New Essentials v2
`la.global` = Essentials v1
`CompanyFile la.global` = AccountRight, New Essentials v2 and Essentials v1
We then can use the endpoint `https://api.myob.com/accountright/` to connect to the AccountRight and New Essentials v2 company files we have been invited to work with.
We also have the AccountRight Postman collection - https://developer.myob.com/api/accountright/accountright-postman-collection/.
If you have any queries that are for MYOB Advanced you would need to email advancedisvs@myob.com.
Thanks,
