How to do a VRBO discount

I'm finding the whole VRBO API a bit awkward. I'm wondering what the best way is to send a "special offer", much like AirBnb, when someone has sent just an inquiry via VRBO. Right now, I am having them send in an actual request to book, then I can send them back an updated quote. I think that's a little weird for the guest, because it looks to them as if they are booking at the higher price than negotiated. Is there an easier way?

Unfortunately, no, this is a known clunky bit and limitation of the Vrbo API:

We're actively pursuing a better solution with Vrbo, but it's complicated and may be awhile.

Also, with the VRBO API, since the booking always shows pending, even on the guest side, after it's been booked, I'm assuming they can never leave a review?

That seems wrong - can you write in to the Helpdesk with a specific example we can investigate?

Hi Ken! Is this still the case or has it been updated with an easier way? Will VRBO charge the guest service fee on the discounted rate or the original request to book amount?

Vrbo will charge service fees on the higher of the original or modified total.
