ServiceM8 Webhooks API
Create and manage object and event webhook subscriptions. Subscribe to changes on specific fields of an object type (such as job or company); when a subscribed field changes, ServiceM8 POSTs the object type, changed fields, uuid, and a resource_url to your callback URL for you to fetch the full record.
