Examples

NOTE: that the provided examples showcase only subscriptions in our API. Please use the GraphiQL API Browser to discover the full API and its documentation and derive GraphQL therefrom.

Example Subscriptions

The operation type 'subscriptions' is used to get pushed updates from the server when certain data changes. GraphQL allows omitting the query type but not the subscription type. There would be no way to distinguish them otherwise.

The GraphQL subscriptions are exposed using the GraphQL over Websocket Protocol.

A GraphQL over Websocket Protocol client implementation for Node.js can be found here.

There are currently two subscriptions available:

• aopdProofs

• trpdTransactions

Authentication for Subscriptions

Please note the dedicated subscription chapter on the authentication page.
