Daemon Console Application Connecting to Business Central

Question

Hi,

Created a daemon console application connecting a local application and MS D365 Business Central.
Based the daemon console app on Quickstart under https://aad.portal.azure.com/
Also using https://api.businesscentral.dynamics.com/ to acquire token

Already able to acquire token already but getting a {"code":"Authentication_InvalidCredentials","message":"The server has rejected the client credentials. error.

Anything I can do for this?

Thanks @AmanpreetSingh-MSFT for the help earlier!

Service to service authentication for automation APIs in Business Central is the answer

Answer 2

This error often occurs if the client_secret you provided is not the correct one. Please try going back to the app registration in the Azure portal for your app, and generate a new client secret and paste it in your code.

Also, can you please confirm which Quickstart you are following?
