I was wondering if there is a way of using a webhook to start a process in Process Services from an external app/system? I have a very simple process that starts, sends an email to alert me that it has started, and then ends. What I was hoping to achieve was the ability to start this process from an external app (using a webhook), the process runs in Process Services, and then communicates a message back to the external app (again using a webhook) that simply reads "process complete" for example. I have asked the question (in the wrong Gitter room!) to which I was advised on using the "Recieve task" trigger in my process and the "Rest call task" trigger to simulate the incoming and outgoing web hooks. I am a bit confused on how I can achieve this using these triggers? (Apologies, I am at a beginner level with Process Services!).
Any help would be very much appreciated, thanks in advance!
