# Approval Workflows for Out-of-Policy Bookings

Last updated September 1, 2026

At a glance

Engine Approvals routes out-of-policy lodging requests to department managers or selected admins by email or text. An approver can approve and book in one step, or decline with a reason.

## How it works

An admin enables Allowed with Approval on a travel policy, chooses approvers, and sets the notification method. When a traveler selects an out-of-policy option, they submit a request from the booking flow. The approver gets an email or text and can approve and book, completing the reservation, or decline with a reason. The traveler sees the outcome by email and on the trips page.

## Who it is for and how to use it

It is for companies that permit justified lodging exceptions but want a decision before booking. Route requests to department managers or to selected admins across a policy. Define clear thresholds, assign approvers who can respond quickly, and tell travelers what to include in a request.
