# Slack Oauth Callback

`GET /chatops/slack/oauth_callback`

Slack redirects here after admin clicks Allow.

No Clerk auth — this is a public endpoint. Trust is established by:
  (a) HMAC-signed `state` proving the install was initiated by a
      known NOSO org via our dashboard,
  (b) Slack's `code` being one-shot and tied to our redirect_uri.

## Query parameters

- `code` string, nullable
- `state` string, nullable
- `error` string, nullable

## Response `200`

Successful Response

- unknown

## Other responses
