Webhook Relay Functions provide an easy way to extract values from webhooks and transform HTTP requests before passing them to their final destination. Function can be reused by any number of Inputs and/or Outputs. Since user doesn’t have to run a server, this type of function service is also known as FaaS (Function as a Service) or Serverless.
