DEVELOPER GUIDE

How to reconnect a dropped Linked Devices session

Design a visible recovery path for disconnected sessions instead of silently losing queued messages.

Developer guide for reconnecting a linked device. Validate the behavior in your own stack before production rollout.

The problem

Model connected, degraded, disconnected and pairing-required states explicitly.

Design the boundary

Pause new sends, alert an authorized operator and expose a short-lived QR pairing flow scoped to the workspace.

Process the interaction

Resume queued messages only after the provider confirms a healthy session; preserve idempotency keys.

Measure the outcome

Measure disconnect frequency, time to re-pair and messages held during recovery.

Can I use it without AI?
