Sensor for GraphQL login

Hi,

Is it possible to check the state of a GraphQL API to make sure that it is running. I want to post data to https://my-api.azurewebsites.net/graphql in the form

{ "query": "mutation { authenticateUser(email: \"demouser@abccompany.com\", password: \"password\") {accessToken refreshToken{ tokenString expireAt } }", "variables": {} }
