If you do not have yet an account with Expedia, be patient! Until further notice, Expedia will only be contracting and onboarding Property Managers located in the following countries: Australia, Japan, New Zealand, Canada, and the United States.
You first need to create your account by contacting them via this form.
Expedia will contact you back to ask you all your details, make sure you inform the team that you want to be connected to BookingSync. A few days after, you will receive an email with your Property Manager name or API profile name (it's the same).
The first batch of properties that you create on Expedia must contain at least 20 properties.
You'll find the detailed connection steps on our manual page How to create my Expedia listings from BookingSync?
