Pause workflows for approval with Chat SDK

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 approvers to 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.id on 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. Get started by reading the approvals documentation . Read more
