Does Rich Returns provide an API to connect external systems?
Yes. Documentation can be found over here in our API Reference and Developer Docs. If you're looking to integrate your fulfillment and logistics process with our platform, our documentation is the right place to look at.
API Keys can be created from within the Rich Returns' Dashboard: navigate to Account / API Keys.
Make sure that your plan includes an API license. API access is an enterprise feature for high-volume merchants and currently available on our Plus Plans.
