GraphQL is an open-source data query and manipulation language for APIs. GraphQL offers many benefits over REST API’s, including:

• Fetching data across multiple sources from a single API call
• Returns only the data that is requested
• Supports validation and type checking
• Autogenerating API documentation

In this video, I’ll show you how to construct a sample GraphQL query to fetch data in ServiceNow and then how we can use GraphQL inside of a ServicePortal widget.

I've made the source code, download links, and widget available in the full blog post, available here: https://serviceportal.io/graphql-in-servicenow/
