AirBNB hold visible to guests?

I did read this article, I am on API. Where will guests be told by AirBNB that a hold will be placed on their card?

I assume guests are told of any holds during the check-out process on Airbnb.

There are help articles on Airbnb's site you can refer guests to if they have questions. Here are some: https://www.airbnb.com/help/topic/1357/security-deposits

This is specifically what came up Chris. I went to do a test run to book, I don't see anything indicating a security hold. I had read the link you sent above earlier today. "Host-required security deposits
Some hosts require a security deposit for their listing. The amount, between $100 and $5,000, is set by the host, not by Airbnb. If you’re a guest and you’re booking a listing with a host-required security deposit, you’ll be shown this amount before you make your reservation." I am not seeing that information being provided to guests although that is the intent.

Airbnb doesn't necessarily create real holds anymore.
