Our current API version is API 4.1 however, for our customers who are using API 4.0 you can still refer the 4.1 documentation here but there are mainly 2 changes that needs to be considered while using 4.0 API.
- The text "v4.1" needs to be removed from he URL
URL Example: 4.1
URL Example: 4.0
- The API key needs to be passed as a parameter rather than in the Header
