Use automations to quickly set up webhooks.
Go to Automation => Triggers and create a new Trigger. Select a trigger that should initiate the webhook, for example, a goal, a certain number of page views. In the right column, as an action, select webhook from the Triggerbee action library.
Triggerbee will call the webhook using a HTTP POST command and send a JSON payload of data regarding the visitor and the session.
Your developer will need to analyze the JSON payload (tip: use a service like https://requestb.in) and develop a script that can do something with it, for example, insert into your system or funnel to a middleware like Zapier.
