We are working on integrating Azure Face API – Liveness Detection in our solution and encountering persistent issues with the session creation and video upload endpoints.
Region: East US
- Endpoint Used:
-
https://xxxxxxxxxxxxxxxx/face/v1.2/detectLiveness-sessions -
https://xxxxxxxxxxx.cognitiveservices.azure.com/face/v1.1-preview.1/liveness/detectLiveness/singleModal/sessions
API Version attempted:v1.2andv1.1-preview.1Error: { "code": "404", "message": "Resource not found" } }
-
Our subscription has "Face.LivenessDetection" listed under properties.capabilities.
We're using correct authentication headers and the v1.1-preview.1 API as mentioned in Microsoft documentation.
The REST API is returning a 404 error when hitting any of the Liveness Detection endpoints.
Questions:
- Is East US region supported for Liveness Detection?
- If not, which regions (e.g., West US, East US 2) currently support this preview feature?We have verified that:
Any official guidance or confirmation would be greatly appreciated

According to the context, there is no specific mention of the East US region's support for Liveness Detection. it is advisable to consult the Azure documentation or support to confirm the availability of this feature in your desired region.
If East US does not support Liveness Detection, you may want to explore other regions such as West US or East US 2.
Kindly refer below link: liveness-detection
Thank You.
