feat(clerk-js): support Slack workspace hints during authentication by tmilewski · Pull Request #10402 · clerk/javascript

tmilewski · 2026-10-23T21:06:06Z

Description

Applications that already know a user's Slack workspace cannot pass it through Clerk's OAuth APIs. Add optional slackTeamIdHint to Slack sign-in and sign-up inputs for low-level, redirect, popup, and unified SSO flows.

The SDK serializes the value as slack_team_id_hint. Reused sign-in attempts prepare the current request's hint on the existing attempt, so a new value is validated and a resolved Protect challenge remains bound to that attempt.

Checklist

pnpm test runs as expected.
pnpm build runs as expected.
JSDoc comments have been added for the public parameter.
Documentation has been updated in the companion docs change.

Walkthrough

Shared sign-in and sign-up parameter types now allow slackTeamIdHint, documented for use with the oauth_slack strategy. Legacy and future authentication flows forward the hint in requests. Reused sign-ins prepare a first factor when the hint is defined or the strategy is enterprise_sso. Tests cover serialization, redirects, popups, continuation, retries, and Protect challenges.

Priority: Normal

Estimated code review effort: 3 (Moderate) | ~25 minutes

Suggested reviewers: wobsoriano, zourzouvillys

Merge Risk: Low · up to 53c98

Typed consumers cannot use the Slack workspace hint through future sign-up updates; adding the optional field is a small follow-up before relying on that API.
