As of March 28, 2024, Booking.com has released the security update related to URL's (website links) and 'authorized email addresses' as part of their security enhancements to address phishing.
This release should help resolve issues related to:
Pre-check-in links not being delivered to Booking.com messaging and showing as [Link Removed],
Payment Page links that are not being delivered to Booking.com messaging,
Payment Request links that are not being delivered to Booking.com messaging,
Emails from ChargeAutomation being rejected entirely
ALL USERS that have Booking.com as a booking source should implement these new security features, and update the settings in their Booking.com account as soon as possible.

For authorized email addresses in Booking.com, in addition to any email addresses you may use to communicate with Booking.com, please add the following:
For authorized URL's in Booking.com (domains, website links) you should add all the following domains:
Do not add full URL's eg. the entire link you would send to a guest, just the domain
app.chargeautomation.com - this domain is the domain for pre-check-in links (if you are not using a custom domain), payment pages, and payment links
your custom domain - all domains will need to be authorized. Your custom domain, if you are using this paid feature, can be found by clicking the logo in the top right hand corner of any page within ChargeAutomation and selecting custom domain
if your custom domain is www.xyz.mydomain.com (example)
we recommend adding both the www version and non-www versions
Example: www.xyz.mydomain.com AND xyz.mydomain.com
