how to pass one bot output as another bot input
Could you please tell more details about your two processes like what kind of output will be generated by first BOT ? So that we can check and help you better in this.
We have an activity Called Invoke Process which Executes a process that is available for the local machine. Can be used to run local packages, as well as processes in Orchestrator, if a connection is available. Have a look at below link
You can always do Invoke Process and pass the arguments
in the Bot1 flow you can invoke the Bot2 flow process so that when the Bot1 done the processing the values will be shared using arguments to Bot2
Hope this helps
