Hello Michael Burshtein

Welcome to Microsoft Q&A .Thank you for reaching out to us with detailed information.

From the provided context, it is understood that although you have a Standard S0 tier Azure Health Insights resource in the East US region, you are encountering a 403 (Forbidden) error when attempting to access the Azure Health Insights – Patient Timeline API.

This 403 error occurs because the Patient Timeline API is currently in preview and has not yet been enabled for your subscription.

The JSON response containing the error code **"**UnsupportedFeature" and the message “Feature is not supported by this subscription.” confirms this behavior.

Does the Patient Timeline API require special access or enrollment?

Yes. The Patient Timeline API is a preview feature and requires explicit enablement. It is not auto‑enabled when an Azure Health Insights resource is created.

Is this API available for Free / Trial subscriptions?

No. The Patient Timeline API is not available for Free, Trial, or Azure Credits–based subscriptions. Preview features are commonly excluded from trial access.

Do I need to request access to this preview feature?

Yes. You must request access to the preview feature.

Please refer to the following link to submit a request, specifically asking for: “Azure Health Insights – Patient Timeline API (Preview) enablement”

Set up preview features in Azure subscription - Azure Resource Manager | Microsoft Learn

Once the feature is enabled for your subscription, the 403 error should be resolved.

Are there any region‑specific limitations?

Yes. There are region‑specific limitations for the Patient Timeline preview feature.

The feature is not enabled in all Azure regions.
Even in supported regions (such as East US), it may still be disabled at the subscription level and requires explicit enablement.

Please let me know if you have any questions.

Thank you!

To address the 403 error you are encountering with the Azure Health Insights Patient Timeline API, here are some insights regarding your questions:

Does the Patient Timeline API require special access or enrollment?
Yes, certain Azure services, especially those in preview, may require special access or enrollment. It is advisable to check the Azure portal or the specific API documentation for any enrollment requirements.
Is this API available for free/trial subscriptions?
Typically, preview features may not be available for free or trial subscriptions. You should verify if your current subscription tier supports the specific API you are trying to access.
Do I need to request access to this preview feature?
If the API is in preview, it may require you to request access. Check the Azure documentation for any specific instructions on how to gain access to preview features.
Are there any region-specific limitations?
Yes, some Azure services may have region-specific limitations. Ensure that the service is available in your selected region (East US in your case) and that there are no restrictions for the Patient Timeline API in that region.

For further assistance, consider reaching out to Azure support or checking the Azure documentation for the latest updates on the Patient Timeline API and its availability.
