Yii2 and HubSpot Integration (CRM)



A developer has been brought in to support a client with technical development support, and has a question:
Does HubSpot integrate with Yii2 for us to track lead source and progression?

Currently, their CRM is built on the Yii2 PHP framework. There have been technical difficulties in integrating Hubspot Marketing data into their CRM. Being new to this subject, we are still unclear if this is a framework issue or an architecture issue.

Does anyone have any examples of creating such an integration with a PHP CRM and HubSpot?
