Creating the Lost in London Connection

🔐 Required Role Permissions: See Connections, Modify Connections, See Connection Key

Before you begin:

You must have a commercial agreement with Lost in London for them to sell your products. To inquire about partnering with them, contact them via lostinlondon.com.
You must have Lost in London created as a Reseller in Ventrata with their pricing (retail, wholesale/commission) defined correctly. Note that this API connection requires that the reseller is set to the "Bill to my account" settlement method.

In Ventrata Dashboard, go to Connections → Connections, click + New Connection, and select Lost in London from the list of partners.
Select Lost in London Reseller from the list of your resellers (must be created before creating a connection). The connection will inherit the reseller's configuration like pricing, allowed destinations, products, etc.
(Optional) You can also set the connection Name of your choosing, which may be helpful if you plan to have multiple Lost in London connections and would like to differentiate between them more easily in the future.
Press the Create Octo Connection button.

📗 TIP

If needed, you can also allow or disallow products or destinations on the connection level, in addition to what you have configured on the reseller.

Mapping Products to Lost in London

Securely share the OCTO API key shown on the connection you've created with your Lost in London contact and ask them to map your products using Ventrata's OCTO API, with pricing (octo/pricing) enabled. Typically, it takes no longer than a few business days for the Lost in London team to complete this.

Your Ventrata configuration is complete. You do not need to take any further steps.

📗 TIP

Lost in London can access all products enabled on the connection, but you can also provide the Product and Option IDs from the connection page when contacting them to specify what to map.

Connection Features Detailed

This section is for anyone who wants to know exactly how the Lost in London connection works: which Ventrata OCTO API calls Lost in London makes, when it makes them, and what that means for you. Each call links to Ventrata's API documentation.

In short: Lost in London 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 Lost in London, so anything you change in Ventrata reaches Lost in London the next time it checks.

Product Mapping	❌	You can't map products from Ventrata. Lost in London maps them on its side, through your account manager or Lost in London's portal. This works as follows: Get Products (`GET /products`) – when Lost in London sets up your connection, and whenever it refreshes its listings, it reads every product enabled on the connection, with its options and units (ticket types such as Adult or Child). Get Product (`GET /products/{productId}`) – Lost in London re-reads a single product to pick up changes to its options, units, booking cutoffs and settings. Mapping on Lost in London's side – Lost in London links each Ventrata option and unit to its own listing and ticket types. Your Lost in London account manager does this for you, or you do it in Lost in London's own portal if Lost in London offers one. You only share the connection's API key. What this means for you: Lost in London can only sell what it has mapped. When you add a product, option or unit in Ventrata, Lost in London may see it on its next refresh, but it won't sell it until it's mapped. So tell your Lost in London account manager whenever you add one.
Content Sync	❌	Lost in London doesn't read your product content from Ventrata. Lost in London uses the descriptions, images and other content set up on its own side, so update your content with Lost in London directly.
Availability Sync	✅	Lost in London checks your live availability in Ventrata. Ventrata doesn't push availability changes to Lost in London. This works as follows: Availability Check (`POST /availability`) – Lost in London 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 Lost in London 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 Lost in London can't overbook a slot that has just sold out, even if its stored availability is slightly out of date. What this means for you: when you close a date, change capacity or sell out in Ventrata, Lost in London shows it only after its next check, so there can be a short delay. Ventrata's check at booking still prevents overbooking.
Pricing Sync	✅	Your prices come back with every availability check, once Lost in London asks for them with the octo/pricing capability. This works as follows: `octo/pricing` capability – Lost in London asks for prices by adding `octo/pricing` to the `Octo-Capabilities` header of its requests. Without it, Ventrata sends availability with no prices at all. Availability Check (`POST /availability`) – with pricing on, each day or time slot comes back with your price per unit (ticket type): the retail price the customer pays and the net price you invoice Lost in London, both from the reseller's pricing in Ventrata (retail and wholesale/commission). Group prices – when Lost in London also sends how many people of each unit type are booking, Ventrata prices that exact group. This matters for Booking Size fares and other group pricing. Booking Reservation (`POST /bookings`) and Booking Confirmation (`POST /bookings/{uuid}/confirm`) – the booking comes back with its final retail and net price, so the booking in Ventrata always records the price it was sold at. ‼️ IMPORTANT – Ask for pricing to be enabled. When you ask Lost in London to map your products, ask them to enable pricing (`octo/pricing`) as well, or switch it on yourself if you map in Lost in London's portal. Otherwise it may be off, and Lost in London won't receive your Ventrata prices.
Promotions Sync	❌	Your Ventrata promotions don't apply on Lost in London. Prices on Lost in London don't include promotions you create in Ventrata. Set up any promotions with Lost in London directly.
Bookings Sync	✅	Bookings and cancellations made on Lost in London 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 Lost in London, Lost in London 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, Lost in London confirms the hold. 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. Lost in London gives these to the customer, who shows them at your entrance like any Ventrata ticket. Expire: if the customer doesn't finish paying, Lost in London 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 Lost in London, Lost in London 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 Lost in London has to contact you. Change: Booking Update (`PATCH /bookings/{uuid}`) – lets Lost in London change a booking in place, for example a new date, time or number of people. Some resellers cancel and rebook instead. ‼️ IMPORTANT – Bookings sync one way, from Lost in London to Ventrata. If you cancel, change or rebook a booking from Lost in London in Ventrata, for example in the Dashboard, Lost in London isn't notified. Contact Lost in London so the booking is cancelled or changed on their side too, or ask the customer to cancel through Lost in London.
Pickups/Dropoff Sync	❌	Lost in London doesn't send pickup or drop-off details with its bookings. If your products include pickups, check with Lost in London how it collects pickup details, or arrange them with the customer.
Custom Questions Sync	❌	Lost in London doesn't send answers to your booking questions. If you rely on booking questions, for example names or dietary needs, check with Lost in London how it collects that information.
Extras Sync	❌	Extras and add-ons can't be booked through Lost in London. Customers can only book your main products and options on Lost in London. Sell extras separately, for example on arrival.
Redemption Sync	❌	Redemptions aren't reported to Lost in London. Ventrata doesn't notify Lost in London when a ticket is scanned or redeemed. Lost in London only sees a redemption if it reads the booking back from Ventrata.
Pass Walkup Scanning Sync	❌	Lost in London pass holders can't be scanned at your entrance without a booking. Customers from Lost in London need a booking made through Lost in London before they visit.
Gift Card Sync	❌	Ventrata gift cards can't be sold or redeemed through Lost in London. Gift cards bought in Ventrata can't be used on Lost in London, and Lost in London can't sell Ventrata gift cards.
