The keys ([runtime expressions](https://github.com/OAI/OpenAPI-Specification/blob/master/versions/3.0.2.md#runtimeExpression)) of the callback objects will be interpolated as the topic of a publish/subscription connection using [graphql-subscriptions](https://github.com/apollographql/graphql-subscriptions). Read the [doc](./docs/subscriptions.md) for explanations and examples regarding its usage.
