Good to know
Booking.com only shows certifications recognized by the Travalyst Organization.
You can see here, which certifications these are:
In order for your certification data to be transferred from BeCause to Booking.com automatically, the following criteria all has to be met:
If the above criteria are fulfilled, your certification will be shown on Booking.com. It may take up to a week for the changes to be shown.
If after a week you cannot see the data, and if all of the mentioned criteria on this page is fulfilled, then please contact BeCause's chat-support (available in the corner of this page).
Have a valid certification
Have a Booking.com hotel ID
Wait for up to a week
Booking.com pulls data from BeCause once a week. Thus your data can take up to a week to be live. You may also be lucky with your timing and it is live almost right after you edited it.
