AWS AppSync GraphQL APIs should not be authenticated with API keys
appsync_graphql_api_no_api_key_authentication
This control checks whether your application uses an API key to interact with an AWS AppSync GraphQL API. The control fails if an AWS AppSync GraphQL API is authenticated with an API key.
Risk
API keys in AppSync can expose applications to unauthorized access if compromised. Avoiding API keys helps reduce the risk of unintended access.
