Connection Features Detailed

This section is for anyone who wants to know exactly how the Hop On Hop Off Plus connection works: which Ventrata OCTO API calls Hop On Hop Off Plus makes (through Ventrata's certified integration), when it makes them, and what that means for you. Each call links to Ventrata's API documentation.

In short: Hop On Hop Off Plus pulls everything it needs from Ventrata. It reads your products, checks your availability and prices, and sends bookings and cancellations. Ventrata doesn't push changes to Hop On Hop Off Plus, so anything you change in Ventrata reaches Hop On Hop Off Plus the next time it checks.

Timings are typical for Hop On Hop Off Plus and rounded, and they can change if Hop On Hop Off Plus changes how it syncs.

Product Mapping	✅	Hop On Hop Off Plus maps your products to its own in its Ventrata account. On each backend-connected product, Hop On Hop Off Plus picks the matching product, option and units from your account on the product's Mappings tab. Products that aren't mapped correctly are highlighted in red, and bookings for them fail. See Ventrata: Operator Backend.
Content Sync	❌	Hop On Hop Off Plus doesn't read your product content from Ventrata. Hop On Hop Off Plus uses the descriptions, images and other content set up on its own side, so update your content with Hop On Hop Off Plus directly.
Availability Sync	✅	Hop On Hop Off Plus checks your live availability in Ventrata. Ventrata doesn't push availability changes to Hop On Hop Off Plus. This works as follows: Availability Check (`POST /availability`) – Hop On Hop Off Plus sends a product, an option and a date or date range. Ventrata answers with each bookable day or time slot, its status (`AVAILABLE`, `LIMITED`, `SOLD_OUT`, `CLOSED` or `FREESALE`), the remaining vacancies, the booking cutoff and an `availabilityId`, which Hop On Hop Off Plus needs to book that slot. Availability Calendar (`POST /availability/calendar`) – returns one summary per day instead of every time slot, typically to show which dates are open in a date picker. Check at booking – when a customer books, Ventrata checks capacity again before it creates the booking, so Hop On Hop Off Plus can't overbook a slot that has just sold out, even if its stored availability is slightly out of date. Typically with Hop On Hop Off Plus: Availability Check: Hop On Hop Off Plus checks each product about every 10 minutes, usually starting about 8 months ahead and covering 7 days per request and looks up to about a year ahead. Availability Calendar: Hop On Hop Off Plus checks your products throughout the day, usually starting today and covering a single day per request, looks up to about 3 months ahead and re-checks the same product and dates about every 2 hours. Checks are busiest between 01:00 and 07:00 UTC, which suggests most checks are live, as customers browse Hop On Hop Off Plus. What this means for you: when you close a date, change capacity or sell out in Ventrata, Hop On Hop Off Plus shows it after its next check. For dates it checks regularly, that's within about 10 minutes. Dates further ahead are usually checked less often.
Pricing Sync	✅	Your prices come back with every availability check, once Hop On Hop Off Plus asks for them with the octo/pricing capability. This works as follows: Typically with Hop On Hop Off Plus: 📗 TIP – If prices on Hop On Hop Off Plus look wrong, check the Hop On Hop Off Plus reseller's pricing in Ventrata first: that's what Hop On Hop Off Plus reads. Hop On Hop Off Plus can take your prices with Backend Pricing on its product, or set its own prices in its account.
Promotions Sync	❌	Your Ventrata promotions don't apply on Hop On Hop Off Plus. Prices on Hop On Hop Off Plus don't include promotions you create in Ventrata. Set up any promotions with Hop On Hop Off Plus directly.
Bookings Sync	✅	Bookings and cancellations made on Hop On Hop Off Plus are created in Ventrata instantly, and customers get Ventrata tickets. This works as follows: Hold: Booking Reservation (`POST /bookings`) – when a customer starts checkout on Hop On Hop Off Plus, Hop On Hop Off Plus sends the product, option, chosen slot (`availabilityId`) and one unit item per person. Ventrata checks capacity again and creates an `ON_HOLD` booking, which holds the places while the customer pays. If there's no longer room, Ventrata rejects the hold. Confirm: Booking Confirmation (`POST /bookings/{uuid}/confirm`) – once payment goes through, Hop On Hop Off Plus confirms the hold, with its own booking reference and the customer's contact details. The booking becomes `CONFIRMED` in Ventrata, and Ventrata sends back your booking reference and the tickets (one per person) or a voucher (one per booking), depending on how your product is set up, each with a QR code and a PDF link. Hop On Hop Off Plus gives these to the customer, who shows them at your entrance like any Ventrata ticket. Expire: if the customer doesn't finish paying, Hop On Hop Off Plus never confirms, and the hold expires on its own and frees the places. Cancel: Booking Cancellation (`POST /bookings/{uuid}/cancel`) – when a customer cancels on Hop On Hop Off Plus, Hop On Hop Off Plus cancels the booking in Ventrata. Ventrata accepts this only if the booking can still be cancelled and the option's cancellation cutoff hasn't passed. Otherwise it rejects the request, and Hop On Hop Off Plus has to contact you. Change: Hop On Hop Off Plus doesn't use Booking Update (`PATCH /bookings/{uuid}`), so a change most likely reaches Ventrata as a cancellation plus a new booking. Typically with Hop On Hop Off Plus: Hop On Hop Off Plus doesn't set a hold time, so the default hold time applies. A typical Hop On Hop Off Plus booking is for about 2 people. It's normal to see more holds than confirmed bookings: holds from customers who don't finish paying simply expire. Hop On Hop Off Plus also checks the bookings it has made, with Get Booking (`GET /bookings/{uuid}`) about every 30 minutes, for example to reconcile its records. ‼️ IMPORTANT – Bookings sync one way, from Hop On Hop Off Plus to Ventrata. If you cancel, change or rebook a booking from Hop On Hop Off Plus in Ventrata, for example in the Dashboard, Hop On Hop Off Plus isn't notified. Contact Hop On Hop Off Plus so the booking is cancelled or changed on their side too, or ask the customer to cancel through Hop On Hop Off Plus.
Pickups/Dropoff Sync	❌	Hop On Hop Off Plus doesn't send pickup or drop-off details with its bookings. If your products include pickups, check with Hop On Hop Off Plus how it collects pickup details, or arrange them with the customer.
Custom Questions Sync	❌	Hop On Hop Off Plus doesn't send answers to your booking questions. If you rely on booking questions, for example names or dietary needs, check with Hop On Hop Off Plus how it collects that information.
Extras Sync	❌	Extras and add-ons can't be booked through Hop On Hop Off Plus. Customers can only book your main products and options on Hop On Hop Off Plus. Sell extras separately, for example on arrival.
Redemption Sync	❌	Redemptions aren't reported to Hop On Hop Off Plus. Ventrata doesn't notify Hop On Hop Off Plus when a ticket is scanned or redeemed. Hop On Hop Off Plus only sees a redemption if it reads the booking back from Ventrata.
Pass Walkup Scanning Sync	❌	Hop On Hop Off Plus pass holders can't be scanned at your entrance without a booking. Customers from Hop On Hop Off Plus need a booking made through Hop On Hop Off Plus before they visit.
Gift Card Sync	❌	Ventrata gift cards can't be sold or redeemed through Hop On Hop Off Plus. Gift cards bought in Ventrata can't be used on Hop On Hop Off Plus, and Hop On Hop Off Plus can't sell Ventrata gift cards.
