 # Azure Digital Twins Postman Collection
 
-The repo contains a single postman_collection.json file that contains a postman collection of requests to the Azure Digital Twins APIs. Currently the focus of the collection is on on the data plane and includes Models, Query, and Twins.
+*NOTE: Due to recent security and privacy concerns, Postman is no longer recommended as a REST API testing tool for Azure Digital Twins.*
 
-We will continue to add updates to the collection on a regular basis until all data plane and control plane API requests are created. If you have any suggestions or problems please create an issue. If you have any question or want to discuss something, please post in the discussion tab.
