Here’s a ShopsBuilder knowledge base article explaining how to add custom information to checkout, especially useful for restaurants, food courts, co-working spaces, and more.

In some business scenarios, it's important to pass custom context with an order - for example:

• In a restaurant, to specify the table number where the QR code was scanned.
• In a hotel, to indicate the room number for room service.
• In a co-working space or event, to include the booth number or location zone.

With ShopsBuilder, you can do this using custom checkout fields via a special startapp link when launching your shop as a Telegram Mini App.
