Our internal API tests use Postman, which you can use as real world examples of how to use the APIs. The tests are responsible for setting up their own data which is why you will see a number of bundles of content being uploaded in order to test against.
Visit our GitHub repository containing our Postman tests.
Note: cURL code examples assume usage of BASH and GNU coreutils. On macOS, you can install coreutils via the Homebrew package manager
brew install coreutils
