We built a GraphQL API explorer directly in our API documentation using Apollo Studio's React component, the `ApolloExplorer`. The explorer provides an intuitive UI, state persistence, and easy integration with our Docusaurus documentation platform. We overcame challenges such as embedding the explorer within iframes and passing custom request headers by utilizing the `handleRequest` prop and persisting the explorer state between sessions using the `persistExplorerState` prop. This integration has greatly benefited our customers building high-performance data products with Propel's API, providing them with a polished and easy-to-use UI for exploring and experimenting with their GraphQL queries.
