If you're seeing "New countries added to partner card and original contract. Addendum can not be sent as original contract not signed yet!" this means your Booking.com account has an unsigned agreement that needs to be completed before you can create listings.
What This Error Means
Booking.com requires you to sign a partner agreement to publish your property. When trying to add a property in a new country, Booking.com can't update that agreement because the original contract isn't signed.
How to Fix This Error
Step 1: Find Your Agreement Email
Look for an email with subject line: "Booking.com - Start partner account registration"
This is what it looks like.
Make sure to check your inbox, spam/junk folder, and the "Promotions" tab in Gmail.
Step 2: Sign the Agreement
Click the link in the agreement email.
Follow the signing process as outlined in the email.
Complete all required sections.
Submit the signed agreement.
Step 3: Retry Creating Your Property
Wait a few minutes after signing for the system to update.
Return to Hospitable and try creating your listing again.
The error should be resolved once the agreement is processed.
If the error is not resolved or you're unable to find the agreement, please reach out to our support team.
