Hi All

I have On-Prem Business Central with Essential License, i want to call the BC web services using POSTMAN for testing, for that i have registered my App in azure portal. And i am able to generate(OAuth 2.0) the token from POSTMAN. But when i call my web services with the token i got this error.

"error": {

"code": "Unknown",

"message": "IDX10231: Audience validation failed. Delegate returned false, securitytoken: 'System.IdentityModel.Tokens.Jwt.JwtSecurityToken'. CorrelationId: a0a947a7-494e-412b-b638-54153ac357a2."

}

i have gone through many document but not able to resolve this. What steps i need to do here to resolve or Is it possible to do this on-prem Business central or not.
Does anyone have idea about this, please provide you feedback.

Thanks for your Help.
