The cURL SDK is actually a collection of examples in raw HTTP format of how you interact with our API. cURL is used on virtually every Linux server and is also Windows compatible. It is unlikely that you would ever use cURL in production because you would incorporate one of our SDKs. However, it is extremely helpful to understand the low-level API’s and how the system works.
The cURL SDK is not required and is for reference purposes only, especially when you are using any of the other language’s SDK.
