A brand-new feature introduced in the new Repeat Customer Insights account is the API (Application Programming Interface).
This will allow you to write code to access the data in your account. Specifically the customer and customer analysis data in this first release.
Any API requires a programmer or programming experience to really use well. It's meant for building software and integrations on top of, not regular day-to-day work. Having an official API will let you integrate the app more into your business processes and could allow other apps to integrate directly.
The plan is to expand the API over time giving you more access to the data, reports, and analyses used by Repeat Customer Insights.
Over time I'll create examples and tutorials about using the API, as well as integration ideas. For now, you can look through the api docs to see what's available and how you might use it.
If you haven't installed yet, you can get started on the app page.
