Issues accessing D365 Business Central API under free trial

I have a D365 Business Central API URL under free trial:

"https://api.businesscentral.dynamics.com/v2.0/{tenant_id}/{environment}/api/v2.0/companies({company_ID})/items"

However, we are facing issues accessing it. Every time we try to access the URL, we receive the following error:

Error: { "error": { "code": "Internal_ServerError", "message": "Sorry, the current permissions prevented the action. (Page 30008 APIV2 - Items Execute: Exclude_APIV2) CorrelationId: c21d1050-dd64-430d-add7-24043

a41b95f." } }

I have administrator and Super user permissions in D365 BC user-card. Could you please suggest a solution?

Also, is accessing the API allowed under free access?

Hi, did the error can occur for other APIs in your list?

The trial version of Dynamics 365 Business Central can connect to various Microsoft services, including the API. The first step is required to provide Postman with the credentials, here are some helpful links about call API using postman, you need to register an app in Azure portal:

Hi, It looks like a permission issue. Please check the Permission Sets in the Microsoft Entra Application Card.

Hope this helps.

Thanks.
