The security update is installed and verified, and the Synci API is available again. Thanks for your patience.

We’re still waiting for the patched packages for part of our infrastructure. Service will be restored as soon as the update is installed and verified. Background syncs keep running, and no action is needed on your side.

As a precaution, we've started the security maintenance early, so the Synci API is unavailable from 15:00 rather than from 15:50 CEST.

API requests, the hosted connection portal and AI assistant connections will return errors until the update is installed and verified. Background syncs and outbound webhooks keep running, so no data is lost.

We're applying a security update to the runtime behind the Synci API. From 15:50 CEST (13:50 UTC) today, 21 October, the Synci app, the API (including AI assistant connections) and the connection portal will be unavailable until the update is installed and verified.

Background syncs to your budgeting apps and spreadsheets keep running, so no data is lost and no action is needed on your side. Depending on when the update is published, this may run into the evening. We'll provide an update when service is restored.
