To see what functionality is available, you can use the explorer for the corresponding API. The explorer not only publishes the schema (what fields, queries and mutations are available) but also allows you to run GraphQL queries and mutations interactively in the browser.To use the explorer, you must first generate a key-token pair as documented here. Once you have created a key-token pair, you can then click onv2 Admin API explorer, orv2 Delivery API explorerunder the Actions column for the corresponding pair to explore the respective APIs.This will open the interactive explorer in a new browser tab or window, and you can immediately start exploring the schema right away with the API key and token automatically populated for you behind the scenes.
