# Please get your Client Id and Client Secret from https://dashboard.groupdocs.cloud/applications. 
# Kindly place Client Id in client_id and Client Secret in "client_secret" argument.
curl -v "https://api.groupdocs.cloud/connect/token" \
-d "grant_type#client_credentials&client_id#xxxx&client_secret#xxxx" \
-H "Content-Type: application/x-www-form-urlencoded" \
-H "Accept: application/json"
# cURL example to join several documents into one
curl -v "https://api.groupdocs.cloud/v1.0/metadata" \
-H "Content-Type: application/json" \
-H "Accept: application/json" \

SDK examples

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 making requests and handling responses and lets you focus on writing code specific to your particular project. Check out our GitHub repository for a complete list of GroupDocs.Metadata Cloud SDKs along with working examples, to get you started in no time. Please check Available SDKs article to learn how to add an SDK to your project.
