Redtie APIs are classified into either production or staging APIs. A production API is one that has been made generally available for public use and is stable. A staging API is one that is still in development or is for internal use and whose stability cannot be guaranteed. Staging APIs may be removed or modified at any time without advance notice.
The current version of production level APIs is v3. When a new version of APIs is made generally available (not beta), the older version will be deprecated and will cease to function within our notice of 3 months. Once that API is removed, any request to it will result in a 404 error.
