A system may include a contact center services system configured to receive a Web Real-Time Communication (WebRTC) call from a WebRTC caller device, and a WebRTC device configured to provide, to a customer web server, a control action application programming interface used to perform control actions for WebRTC calls in the contact center services system. The WebRTC device may be configured to receive an instruction to perform a control action for a WebRTC call from the customer web server via a WebRTC access server and forward the instruction to the contact center services system. The contact center services system may be configured to retrieve a Uniform Resource Identifier (URI) from the received instruction, identify that the WebRTC call is associated with the control action based on the retrieved URI, and execute the control action on the identified WebRTC call based on the instruction.
