# Get Spend Alerts and Approvals in Slack with Husk

> Husk Slack integration delivers spend alerts, approval requests, and receipt reminders directly to your channels. Keep your team informed in real time.

Husk Slack integration brings financial notifications into the place your team already works. When a card is used, a receipt is missing, or an approval is needed, Husk posts a message to the Slack channel you choose. This page shows you how to install the app and configure which events trigger notifications.

## Notification types

<AccordionGroup>
  <Accordion title="Transaction alerts">
    Husk posts a summary each time a corporate card is used, including merchant, amount, and card holder name. Large or unusual transactions are flagged with a warning icon.
  </Accordion>

  <Accordion title="Approval requests">
    When a team member submits an expense or requests a spending limit increase, the approver receives a direct message with Approve and Decline buttons.
  </Accordion>

  <Accordion title="Receipt reminders">
    If a transaction lacks a matched receipt after a configurable delay, Husk reminds the card holder via direct message to upload or forward the receipt.
  </Accordion>

  <Accordion title="Spend limit warnings">
    Husk warns channel admins when a team or card approaches its configured spending limit, so you can adjust controls before a decline.
  </Accordion>
</AccordionGroup>

## Tips for effective use

* Route high-value transaction alerts to a dedicated finance channel so they do not get lost in general chat.
* Set receipt reminder delays based on your company policy, for example 24 hours for travel expenses and 7 days for software subscriptions.
* Use approval request direct messages for managers who need to act quickly while traveling.

<Info>
  You can disconnect or reconfigure the Slack integration at any time from **Settings** > **Integrations** > **Slack**.
