Complete the Slack account link

GET /v1/integrations/slack/link/callback

The final leg: the user has proved both who they are in Slack and who they are in Hanzo, and this binds the two. It answers a short confirmation page telling them to return to Slack.

The Hanzo credential obtained here is sealed into the connected workspace's own KMS namespace; it is never written to a database column and never logged. A deployment whose secret store is unavailable refuses the link rather than completing it without custody of the credential.

This is one leg of a three-leg flow, and the legs are not interchangeable: a browser is expected to arrive here only from the leg before it. The link URL's state proves the prompt was server-minted and carries the CHAT it started from — it is provenance only, and it never decides which account gets linked. The account identity always comes from the platform's own verified sign-in and a host-bound cookie, so forwarding a link to someone else cannot bind their account, and a session lifted into another browser is refused rather than completed. Each link is single-use, and a deployment without linking configured answers 503.

Request

GET /v1/integrations/slack/link/callback takes no parameters and no body — the credential is the whole request.

Response

The document declares no response body for this operation. It answers 200 on success and the platform error shape on failure — see Errors.
