@HugoTrentesaux pour le moment ton instance Squid ne propose pas de subscription, mais il suffit de les activer avec une option côté serveur: > OpenReader supports [GraphQL subscriptions](https://www.apollographql.com/docs/react/data/subscriptions/) via live queries. To use these, a client opens a websocket connection to the server and sends a `subscription` query there. The query body is then repeatedly executed (every 5 seconds by default) and the results are sent to the client whenever they change. > **To enable subscriptions** , add the additional --subscriptions flag to the squid-graphql-server startup command. The poll interval is configured with the --subscription-poll-interval flag. For details and a full list of available options, run > > `npx squid-graphql-server --help` > **[Subscriptions | Subsquid](https://docs.subsquid.io/sdk/resources/graphql-server/subscriptions/)** > > Subscribe to updates over a websocket --- _[View the full topic](https://forum.duniter.org/t/squid-pour-duniter-episode-2/11713)._
