The Moxie integration suite exposes both webhook and public API functionality which allows developers to expand the capabilities of Moxie by integrating third party software.
Webhooks send data out of Moxie when various events occur within your workspace and the Public API allows you to create and modify various objects in your workspace. Both the webhook and public api functionality utilize JSON over HTTPS to move data in and out of the platform.
To enable the custom navigate to Workspace Settings --> Connected Apps --> Integrations. You will see an option for Custom Integrations. Click the "Enable" button to create your API profile, API key and webhook authentication settings.
