## Approving trip requests in the **Trips** app

As an approver in your company's workflows, you can approve and return trip requests to their owners in the Payhawk Web Portal from the **Trips** app.

1. In the [Payhawk Web Portal](https://portal.payhawk.com), go to the **Trips** app.
2. Navigate to the **Approve** tab.
3. Select the desired trip request by clicking on it.
4. Click on the **Approve** button. As a result, the trip request will be approved.

If you’re an approver who covers several travelers on the same group trip, you can approve them together from the **Trips** app using the team filter.

> [!TIP]
> When a trip uses per diem mode, the trip request shows a per diem line next to the flight and hotel amounts, in place of an allowance. The per diem itself is not flagged as in or out of policy. Approving the trip creates a draft per diem expense for the traveler. If the traveler later submits a per diem above the approved amount, a separate per diem discrepancy approval comes to you before payout.
