Calendly
When a new event gets created via Calendly, create a Lead in ERPNext and add a comment with more information. If the Lead has already been converted, the comment will be added to the corresponding Customer instead.
Note: Currently this app can only receive webhook calls. It doesn't create the actual webhook so it's pretty useless by itself. Don't install it unless you want to contribute to the development.
