Running this application.

• ./gradlew clean build
• ./gradlew bootRun

Application will be exposed on port 8081. You can send your POST request against http://localhost:8081/nintendo/team/graphql.

Playing with this API

Checkout the attached Postman Collection for more examples. Below is one for querying all team details

query teamData($nintendoId: NintendoId!){
    myName(nintendoId: $nintendoId) {
        nintendoId
        firstName
        middleName
        lastName
    }
    myTeammates(nintendoId: $nintendoId) {
       nintendoId
       teamId
       teamInfo {
           managerId
           teamName
