# Sync Slack channels

> POST /webhook/slack/channels/sync/

Fetches the connected workspace's current channel list from Slack and re-caches it — call this before [List Slack channels](/api-reference/management-api/integrations/slack-channels) if you need up-to-date data.

<Note>
  Requires the account's `INTEGRATION_SLACK` quota. No request body.
</Note>

<RequestExample>
  ```bash cURL theme={null}
  curl --request POST \
    --url 'https://api.scanova.io/webhook/slack/channels/sync/' \
    --header 'Authorization: YOUR_API_KEY'
  ```
</RequestExample>

<ResponseExample>
  ```json 201 theme={null}
  {
    "channels": [
      { "id": "C0123ABC", "name": "general", "is_private": false, "is_member": true }
    ]
  }
  ```
</ResponseExample>

If Slack reports the workspace's token as revoked or invalid, the workspace is flagged `reauth_required: true` (visible via [Slack connection status](/api-reference/management-api/integrations/slack-status)) and this call returns `400`.

`404` if there's no connected Slack workspace.

        Send your Management API key as the raw value of the Authorization
        header — no "Bearer " or "Token " prefix, and no other characters.
        Example: `Authorization: 401f7ac837da42b97f613d789819ff93537bee6a`. A
        header containing more than one space-separated part is rejected
        outright. Requests also require the request's Host header to be the
        management API host (e.g. api.scanova.io) — the same key sent to the
        regular API host will not authenticate.
