You can build human-in-the-loop approvals with Chat SDK through the new chat/workflow subpath. One requestApproval call posts a card with Approve and Deny buttons and suspends a Workflow SDK workflow until someone decides.
The wait can last seconds or days and survives deploys and restarts. You don't need an approvals table, an onAction handler, or a polling loop:
Start the workflow from any handler, and Thread instances serialize across the workflow boundary automatically. The card handles the rest:
- Scoped approvers: Pass
approversto restrict who can decide. Clicks from anyone else post a notice, and the workflow keeps waiting. - Verified decisions: Chat SDK checks the platform's signature on every click, so the
user.idon the result is the person who decided. - Audit trail: Once a decision lands or the timeout elapses, the card is edited in place with an outcome line, preventing stale clicks.
