I am in the process of evaluating Hubspot best practice for a CRM integration. I would like certain actions within Hubspot trigger actions within our back-end system. For instance if a user takes action on a specific webpage, or clicks through to specific links I would like it to trigger action within our CRM system. I am wondering can I query these kinds of behaviors using the API for integration? Can I trigger the action on another server once an action is performed within hubspot?
