Webhooks are user-defined HTTP callbacks.
They are automated messages sent from apps to PROCESIO when something happens. Webhooks have messages (called payload) and are sent to a unique URL (i.e. PROCESIO's address).
Webhooks can be used to receive data from apps and services when an event occurs. Also, webhooks can be used as triggers for process flows when we want to receive data and run a process based on the data. This allows several different services to connect to PROCESIO and run a process when data is received.
Webhook In, refers to the fact that Procesio receives payload from a third party app.
