Lakehouse Connection issue using SQL Endpoint

[Pratik_0527]

Hi All,

Im trying to connect to Fabric Lakehouse through a C++ using the SQL Endpoint. I have registered the APP in Azzure and generated a client ID. Using this to connect im getting below error. Can somebody guide what needs to be done here? Are we missing anything ?

Error Message : "Error details: error invalid_client error_description: AADSTS650057: Invalid resource. The client has requested access to a resource which is not listed in the requested permissions in the client's application registration. Resource value from request: https://pbipneu9-northeurope.pbidedicated.windows.net. Resource app ID: cb4dc29f-0bf4-402a-8b30-7511498ed654. List of valid resources from app registration: 00000003-0000-0000-c000-000000000000."

Hi @Pratik_0527  ,
Thanks for reaching out to the Microsoft fabric community forum.

Check these troubleshooting steps:

-> Please ensure that the caller has contributor or higher workspace role.

-> The required delegated scope to call lakehouse are Lakehouse.ReadWrite.All or item.ReadWrite.All, ensure                 these are in place.

->  Since you're calling from a C++ app make sure you're using the correct token endpoint.
       For Ex if it is to get lakehouse it should be something like this
       GET https://api.fabric.microsoft.com/v1/workspaces/{workspaceId}/lakehouses/{lakehouseId}

Hi @v-nmadadi-msft We have verified the enpoint that we are using with the help of Native driver by microsoft and the SSMS tool. Both are able to connect to the Lakehouse. 
Also we are not using CURL as the "GET" request suggested by you shows something like CURL API.
Let us know if Lakehouse connectivity requires CURL API calls?

Hi @Pratik_0527 ,

If you are trying to connect to SQL endpoint using a C++ app,
you have to use REST API and the supported features for it are 

Items - REST API (SQLEndpoint) | Microsoft Learn

whereas for lakehouse these are the supported features

Items - REST API (Lakehouse) | Microsoft Learn

Hi,

Thanks for the revert, Let us take a look at this REST API usage and feasibility in our code setup. We will surely try it and update with our findings.

Hi @Pratik_0527 

have you done this?

Navigate to your app registration in the Azure Portal.
2. Under API permissions, click + Add a permission → Microsoft APIs → Power BI Service.
3. Select delegated or application permissions (e.g., `Dataset.ReadWrite.All` or `Reports.Read.All`, depending on your use case).
4. Click Add permissions and have an admin grant tenant-wide consent

Hi @nilendraFabric we do have this permission setup present in Azzure. Also we are not using Power BI. its a C++ driver code.
