Hi @MDPublisher , welcome to the Activepieces community!
In the link you can find the documentation regarding piece development. Fork Repository - Activepieces I think YouTube can be a great teacher in better understanding the ins and outs
I saw you want to connect VBOUT, there is a piece available so no need to build any more.
You might also want to keep a look at this thread, as we are hoping for more detailed insctructions on developing pieces. The learning curve can be really steep Developing a piece Step-by Step
Have fun exploring!
