Currently, I have implemented only the RTM client and wanted to provide the possibility to add an Events API implementation later. The other benefit would be that the user needs only one CS to listen and multiple processors could use the same connection (WebSocket in this case). for example, one processor filters "message" type and another "file_shared" type and they can share the same slack connection. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
