A data integration is an integration that stays in sync and continuously updates - systems that continuously store customer feedback such as Intercom, Zendesk, Delighted, and Salesforce are good examples. You pay for each Data integration connected to EnjoyHQ.
Non-Data integrations do NOT continuously sync. Products such as Slack, JIRA, Trello, Zapier, and email forwarding are examples of non-data integrations, and are included in your account at no additional cost.
