Introduction
The steps below will guide you through setting up Merchant Warrior as a payment option for your Hostaway reservations, using Hostaway’s custom fields and automation features.
Before you begin: Please contact Merchant Warrior support to enable the Hostaway service on your account. This must be done before proceeding with the setup instructions below.
How it works: Once set up, a payment link (PAY.Link) will automatically be created for each new reservation. Any payment made through this link will be automatically reflected on the corresponding reservation in Hostaway.
