Co crear in product ed integrar pajaments

The structure of a product card and the list of payment systems are covered in the "Bot settings" topic. Below is just the sequence.

• First connect a payment system: "Settings" → "Shop" → "Integrations" → "New integration" → pick a system (e.g. YooKassa) and enter its details
• Open "Shop" → "Products" → "New product"
• Enter a name, and optionally a description and image
• In "Payment settings" pick the integration you created, the currency, and the price
• Fill in "Seller details" (email, phone, a link to the offer) — this is required to accept payments
• Expand "Post-payment actions" and add, for example, "Add tag" from the action catalogue
• Click "Save" — you'll get a payment page like i.tvoybot.com/product/…
• Add the "Buy product" button to a message to sell right in the conversation
