Deployment to app.powerbi through restapi from a Azure client app

[nganesh]

I am trying to deploy data model and report from desktop to app.powerbi though a client app configuration. Data models are owned by 3 different services accounts for different environment. I am able to refresh the datamodel in each of these environments but unable to deploy the model / report (getting 404). I feel I am missing some steps with the app registration. Can you please help with the steps or point me to the documenation for this.

Sorry for the delay in response. I am able to create workspace, impact dataset, assign permissions etc. Our initial setup included Azure service account (not principal) for EntraID authentication with snowflake. We recently decided to move away from password based service accounts. Is there way to define the azure service principal in the database connection parameter in the dataset - ideally key-pair configured in Snowflake

Hi @nganesh ,

Power BI supports only Microsoft Entra ID (Azure AD) OAuth-based SSO or username/password for Snowflake not key‑pair authentication. Snowflake integration uses Microsoft Entra ID for SSO, not custom auth schemes such as key pairs.

Please refer below link.

I hope this information helps. Please do let us know if you have any further queries.

This seems to be a recent enhancement to the PowerBI.  I get the following error while adding the pvt key.

Hi @nganesh ,

We understand this appears to be a product bug introduced with the January 2026 release, related to recent ADBC changes.  As a reference, you may review the following documentation, which outlines the current ADBC integration and is still in preview

Hi @nganesh ,

Thank you for reaching out to the Microsoft Community Forum.

When Service principal enabled and lacks workspace access, then you will get 404 (PowerBIEntityNotFound) error. Because the API hides objects that you don’t have rights to.

Please try below things to fix the issue.

1. Please verify that Tenant setting “Service principals can call Fabric public APIs” is Enabled and includes your security group.

2. Ensure that your service principal or its group is Member/Admin of each target workspace.

3. Ensure you are using /v1.0/myorg/groups/{groupId}/imports not the My Workspace import unless that’s intended.

Hi @nganesh 

When you're getting a 404 error, that means something is not found, and that potentially could be, not. The App Workspace GUID or the data set GUID potentially. Can you provide more details and show us the error message that you are getting for us to help you further?
