Abstract: Embodiments of the present invention are directed to a unified messaging proxy and a method thereof. The unified messaging proxy advantageously enables a user to be communicatively coupled with the same account on a messaging platform using multiple end user devices at the same time, allowing the user to read messages on a first end user device and send messages from a second end user device. The unified messaging proxy manages the multiple end user devices and intercepts all messages to and from the multiple end user devices and the messaging platform. From its perspective, the messaging platform only sees a single client messaging application.
