Abstract: A data communication method, apparatus, and device, a computer-readable storage medium, and a computer program product. The method includes: generating a communication request in response to a trigger operation for a communication control in an embedded subroutine, the communication request being used for requesting to communicate with a target user associated with the embedded subroutine, invoking a communication service plug-in according to the communication request, and communicating with the target user in the embedded subroutine through a first service function provided by the communication service plug-in, and performing, in response to a trigger operation for a second service function provided by the communication service plug-in, service interaction with the target user in the embedded subroutine through the second service function in a process of communicating with the target user.
