Hi @starkedge, the Webhooks actions from within Developer Accounts will simply send over the JSON representation of a contact, company or deal to the URL when a specific contact, company or deal is updated, created, or deleted. Note - these events are only sent to the webhook URL if the application you set up webhooks for is installed in your account. Normally, people will subscribe to changes on a contact, company or deal, then send the payload to a webhook URL managed by them, format the incoming data to match what the external CRM needs, and then send the newly formatted payload to the external CRM.
