I can generate the token but after that this error is arising. What is the issue?

Hi @Padmanabhan ,

A 403 error when using a Service Principal with Fabric APIs is usually related to configuration or permission issues rather than the code itself. Based on what you described, these are the most common causes you should review:

1. Service Principal not enabled at tenant level

This is one of the most frequent issues.

Even if the Service Principal has access to the workspace, it must be explicitly allowed at tenant level.

What to check:

• Go to Fabric Admin Portal → Tenant Settings → Developer settings
• Ensure that "Service principals can use Fabric APIs" is enabled

If this is disabled, all API calls will return 403, regardless of workspace permissions.

2. Role limitations (try a higher role)

Some Fabric API operations require higher permissions than Contributor.

To quickly rule out a permission issue, I would recommend:

• Temporarily assigning Member or Admin role to the Service Principal
• Retesting the API call

If it works, then the issue is clearly related to insufficient permissions with the Contributor role.

If my comment helped solve your question,  it would be great if you could mark it as the accepted solution and give me like. It helps others with the same issue and it also motivates me to keep contributing.

Thanks a lot. I really appreciate it

Does the App have API permissions ?

Hi,

Looking at the error:

"errorCode":"InsufficientPrivileges","message":"The caller does not have sufficient permissions to access the requested resource", ,"resourceType":"Workspace"}

This seems to be a permission issue. Can you check whether you have access to the workspace?

[Padmanabhan]

Hi,

Yeah i enabled the workspace access to the service principal and granted contributor role but the error arises.
