Build any ticketing experience and connect with your stack
Your ticketing never works alone. Orders have to reach your CRM, attendees your marketing tools, sales figures your finance team. Getting that data out of a back office usually means a CSV export, a spreadsheet, and the same chore again the following week.
And the moment you want something slightly different, or a sync with an in-house tool, you are waiting on a feature that may never fit your need exactly.
That is why we are opening our API. You can now reach the engine room of your ticketing. Your developers, or your agency, work on the engine that powers your sales, and can read and drive your events, orders and tickets from anything they build.
What's available:
- 🔑 API keys. Create and manage your organisation's API keys yourself, straight from the Studio.
- 🧪 A developer portal with a Sandbox. Explore the API and fire real requests with your own keys, before writing a single line of code.
- 📜 API logs. See every call made with your keys, so you always know what your integrations are doing.
- 🧩 More than 16 endpoints. Events, orders, tickets and more, usable from today.
Why it matters:
- 🎨 Tailor-made ticketing experiences: build the buying journey your audience expects, on your own channels and in your own brand.
- 🛠️ Your own applications: build apps and tools on a powerful API, from a mobile app to an internal dashboard.
- 🔌 Connected to your tools: your sales feed your CRM, your marketing tools and your accounting with no manual export.
- 🚀 Room for your most advanced use cases: the flexibility to answer the needs no standard feature covers.
🎉 The result: Billy fits into your tools rather than the other way round, and your buyers get exactly the ticketing experience you had in mind for them.
Improvements
Studio
- You can now install the Studio on your phone like an app, and your scan statistics are easy to read on a small screen while the doors are open.
- The Studio gets a new look, in Billy's new brand identity.
- The seating configuration page gains a Summary view showing the current occupancy of your venue, and a button to download the full seating report for the session on screen.
Tickets
- You can now change the language of your guests' tickets, one by one or in bulk, and their tickets are regenerated in the new language.
Offers
- When you change an offer's VAT rate, items already sold move to the new rate, for consistent sales figures.
Store / Products
- You can now ask buyers to personalise a product at the time of purchase, for example a name and a number to print on a sweatshirt, whether it is sold on its own or in a bundle.
Event store
- Add-ons are now offered after seats have been chosen, with the booking countdown clearly visible: nobody picks extras any more without knowing whether their seats are secured.
- Buyers who hold several tickets can now resell them one by one from their order confirmation page, when resale is enabled.
- Sold-out offers now show a compact "Sold out" pill instead of a full-width banner.
Fixes
Studio
- Fixed sessions ending on another day looking like single-day slots: their end date is now shown.
- Fixed the stock breakdown tooltip, which now lists sessions in chronological order.
- Fixed a text editor issue when you started typing in an empty field.
- Fixed the live preview, now properly centred on screen.
Orders
- Fixed service fee refunds, which now match to the cent what the buyer paid.
- Fixed a rare case where an order cancelled at the very moment it was created could be refunded twice.
Emails
- Fixed the order confirmation email title, which addressed every reader as male in French, Spanish and Italian.
Event store
- Fixed the missing border on a selected offer card.
- Fixed the spacing between a product's variant options.
