Added exists operator to GraphQL API

23 September 2021
Enhancement
GraphQL
To improve the developer experience for you we have added an exists operator to our GraphQL API. This improvement to the API design is now the recommended way of checking the existence of query results because
it allows the platform to optimize the query towards short response times and
it avoids you finding workarounds with other query fields to achieve the same.
Changes:
[GraphQL API] Added the Boolean exists field to all QueryResult types.
The following changes were introduced in terms of GraphQL SDL:
