# Hostaway instant booking shows ‘Bad Request’ at checkout

When a guest confirms an instant booking on a Hostaway property that collects payment on the guest portal, checkout shows a 'Bad Request' error.

**Why this happens.** This was caused by a bug in HomeRunner, corrected in production on September 9, 2026. Before that date, an instant booking with no card field on the website was rejected before it reached Hostaway, so no reservation was created.

**What to do.** No configuration change is needed on your side. If you saw this error before September 9, 2026, run a test booking again.

**Expected flow.** The checkout should now work like this:

1. The guest completes the checkout form on your site, with no card field.
2. The reservation is created in Hostaway immediately and marked as coming from your website.
3. The guest is sent to the Hostaway guest portal link for that reservation, where payment is collected.

If you still see 'Bad Request' after September 9, 2026, contact support with the date and time of the attempt and the property name so the attempt can be traced.

Still stuck? [Contact the HomeRunner team](https://homerunner.io/contact/) with your site address and what you tried, and we take it from there.
