In order to connect an ActiveCampaign data source you need an ActiveCampaign account url and an API key.

Your API URL can be found in your account on the My Settings page under the "Developer" tab. The url should be on the format https://myaccountname.api-us1.com.

Your API key can be found in your account on the Settings page under the "Developer" tab. Each user in your ActiveCampaign account has their own unique API key.
