OAuth 2.0 Client Credential | "You do not have the following permissions on Page APIV1 - Customers: Execute." Error

(0) ShareShare
ReportReport
Posted on by 10

I am new to Business Central and I have an API that needs to consume Business Central API.

I have setup the application in Azure AD and also setup the created app in Azure in Business central.

However, whenever I am invoking an API in BC using the token I receive from "https://login.microsoftonline.com/{tenant}/oauth2/v2.0/token" endpoint I am getting an error.

I am not sure what permission I need to assign to the registered application. I have assigned Admin, Full access and Super but no luck.

Error:

{
"error": {
"code": "Internal_ServerError",
"message": "You do not have the following permissions on Page APIV1 - Customers: Execute.\r\n\r\nTo view details about your permissions, see the Effective Permissions page. To report a problem, refer to the following server session ID: '295'. CorrelationId: 81c53d83-6843-4da9-8251-2f1980ef2ad4."
}
}

    Hello,

    Does this work when using tools like Postman?

    Thanks.

    Hi Marco,

    Thanks for your response. I have already figured it out.

    I figured that our Business Central staging was running at version 8.2 and oAuth2.0 implementation only runs on version 8.3.

    The permission error was misleading though.

    Hello,

    You are right, sometimes the error messages are not that clear. Glad that you figured it out though and shared it with the community.

    Thanks.
