SiteFlow has a number of available API’s that are RESTful HTTP based API’s. Where possible, we have exposed resource-oriented access using standard HTTP verbs and respond with standard HTTP status codes.
When communicating with the API directly, JSON will be returned in all responses including errors. If you are using one of our SDKs, the SDK will transform the JSON responses into language-specific OneFlow objects.
Any off-the-shelf HTTP client written in any language should be able to access the API easily.
