I am building a plug-in for a platform called monday.com, how do I construct a webhook to listen to a particular change in the user’s board? This webhook should start listening when the user “subscribes”, or starts using our program.

I think I have properly built the API, however I don’t know how to make the webhook interact with the API. I need someone to give me a template of how to build it. The platform uses GraphQL to send information and make changes to the board.
