Using an SDK (API client) is the quickest way for a developer to speed up the development. An SDK takes care of a lot of low-level details of makingRequests and handlingResponses and lets you focus on writing code specific to your particular project. Check out our GitHub repository for a complete list of GroupDocs.Merger Cloud SDKs along with working examples, to get you started in no time. Please check to Get Supported File Formats article to learn how to add an SDK to your project.
