Flexie CRM API is organized around REST. Our API has predictable, resource-oriented URLs, and uses HTTP response codes to indicate API errors.
We use built-in HTTP features, like HTTP authentication and HTTP verbs, which are understood by HTTP clients. We also support cross-origin resource sharing, allowing you to interact securely with our API from a client-side web or mobile application. JSON is returned by all API responses, including errors. We will send information on new additions and changes to Flexie CRM API and also changed on SDK libraries we announce on the mailing list. Be sure to subscribe to stay informed.
