Our API is completely independent of your operating system, database system or development language. You can use any language and platform that supports HTTP to interact with our API. However, manually writing client code can be difficult, error-prone and time-consuming. Therefore, we have provided and support API SDKs in many development languages in order to make it easier to integrate with us. If you use SDK, it Replaces the Watermark API calls and lets you use GroupDocs Cloud features in a native way for your preferred language.
