Prebook rate from search step

This call is available to only certified partners who don’t use the Retrieve hotelpage call in their flow.

https://api.worldota.net/api/b2b/v3/serp/prebook/

ℹ️

This call is required if you don’t use the Prebook rate from hotelpage step call.
Request this call right after the SERP calls withing 6 hours.

The call checks if the requested rate is still available before it can be booked and improves the booking success rate:

When the original rate is not available, the system searches only for alternative rates of the same room type and board type (e.g., switching between refundable and non-refundable conditions within the price_increase_percent limit). The search does not extend to different room types or board types. If an alternative rate is found, new book_hash and match_hash values are returned.
In cases where the same rate cannot be found and a price increase is permitted via the price_increase_percent field. The call will attempt to find the same room and board type at an increased price, but not exceeding the allowed percentage. The value in the payment_options field may change.

ℹ️

The limitations:

The recommended call timeout is 60 seconds.
The minimum call timeout is 30 seconds.
