Hi

China Azure has its own endpoints for login/authentication. here is the reference: https://learn.microsoft.com/en-us/previous-versions/office/office-365-api/api/o365-china-endpoints#azure-openid-connect-and-oauth

You cannot use the command Get-D365LcsApiToken, as your doing reference: https://www.powershellgallery.com/packages/d365fo.tools/0.5.50/Content/functions%5Cget-d365lcsapitoken.ps1

You need to re-engineer the PS, using:

AADOAuthEndpoint = "https://login.chinacloudapi.cn"'

$LcsApiUri = "https://lcsapi.lcs.dynamics.cn" (I am not sure if Microsoft has a LCS for China as they do for EU. But if not just use normal LCS: https://lcsapi.lcs.dynamics.com/)

I can use Postman to obtain tokens, but when using D365fo.tools, there will still be errors. This command may not be applicable to China

Hi @Hu, Ethan

when you use it from Postman, which URL you pass for authentication?

Is that https://login.chinacloudapi.cn or is that something else? how your URL for the call looks like and what is inside the body

Hi @Sohaib Cheema,

The post URL is https://login.chinacloudapi.cn/{tanentid}/oauth2/v2.0/token.

The parameters in body are set according to Microsoft documentation.
