Below is a summary of various components demoed in the video.

1. GraphQL API -> This is the API definition that has schema, graphql scripted resolver and

graphql resolver mappings.

2. Script include -> This contains the functions needed to perform CRUD operations in

ServiceNow and provide relevant output to GraphQL API

3. Fix script -> Is used to test the script include to ensure that it has relevant

configuration needed to provide response to API calls.

4. graphql scripted resolver -> Is a script-able configuration that calls script include

from graphql api

5. graphql resolver mapping -> This maps query defined in graphql schema with graphql

scripted resolver.
