Prebook rate from hotelpage step

ETG API V3

Hotel search

🆕

The Sandbox environment is available exclusively to new partners who begin their integration in Q4 2025.

https://api-sandbox.worldota.net/api/b2b/v3/hotel/prebook/

ℹ️

This call is required if you don’t use the Prebook rate from search step call.

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.

Sandbox limitations

⚠️

Use all field values and API keys obtained from the sandbox environment only within the sandbox. Don’t mix them with test or production environments.

Make another request with a new partner_order_id.
