Partner Centre API

Question

Hi,

I am trying to use the following API call: Get a customer's service costs line items
https://learn.microsoft.com/en-us/partner-center/develop/get-a-customer-s-service-costs-line-items

I can see that it doesn't support the standalone authentication that other API calls do and you have to use the App+User credentials method.
When I try use the Web App in partner Center App Management I get a 403 This resource can't be accessed by application credentials error.

I have registered a new Native app through the Partner Centre and followed these instructions to grant permissions in Azure AD. (https://learn.microsoft.com/en-us/partner/develop/api-authentication) However I am still getting the same 403 error.

I am running out of ideas now on what to try next.

I am using Postman to send the GET request.

URL: https://api.partnercenter.microsoft.com/v1/customers/{CUSTID}/servicecosts/mostrecent/lineitems
AUTH: Bearer {TOKEN}

The Token was obtained by using a POST request on the following URL
URL: https://login.microsoftonline.com/{PARTNERID}/oauth2/token
Body:

• client_id - {APPID}
• client_secret - {APPSECRET}
• grant_type - client_credentials
• resource - https://graph.windows.net

Any help is greatly appreciated.

Thanks,
Danny

Answer 1

Good day, i am facing the exact same issue. Were you ever able to resolve this?

Answer 2

I'm able to retrieve the token with the following:

• client_id - {APPID}
• client_secret - {APPSECRET}
• grant_type - client_credentials
• resource - https://api.partner.microsoft.com
• tenant_id - {TENANTID}

Unfortunately the call to the API gives me a 99999 error.

{
    "error": {
        "code": "accessDenied",
        "message": "The caller doesn't have permission to perform the action.",
        "innerError": {
            "code": "99999",
            "message": "GenericError",
            "details": null
        }
    }
}
