Audience validation failed when setting up OAuth On premise

Posted on by Valentine Motin

Hi everyone,

I'm trying to setup API with OAuth on business central On Premise, but when calling the API with Postman i get the "audience validation failed" error. I browsed through a lot of forums but didn't find a solution that's working for me.

I've set up my configuration using this guide https://learn.microsoft.com/en-us/dynamics365/business-central/dev-itpro/administration/register-app-azure

I can get the token just fine, but i get the error when calling any API.

I tried changing the audience in postman and changing the scope but neither did anything in my case.

This is the complete message i get in the event viewer

Any idea what could be the issue ?
