Cross-border paymentsHow It Works
Accepting Payments
User clicks "Buy"
β PAYchat payment screen opens
β User enters PIN to pay
β Webhook notifies your server
β Order confirmed & shipped
Sending Rewards
User completes a mission
β Your server calls the withdrawal API

Settlement is instant. Funds hit your balance the moment payment completes.
Integration Steps
1. Register as a Partner (1 min)
Select a plan on the Partner page in the mini app β API Key issued instantly
2. Set Up Webhooks (1 min)
Partner page > Webhooks tab > Enter your URL
3. Create a Payment Link (3 min)
json
POST /api/partner/payments
{
"amount": 5.00,
"description": "Limited Edition T-Shirt",
"metadata": { "user_id": "user_123",
"item": "tshirt_black_L"
}
}
Show the payment_url from the response to your user. That's it.
Webhook Data
When a payment completes, your server receives this:
json
{
"event": "payment.completed",
"data": {
"payment_id": "pay_ABC123",
"amount": 5.00,
"payer": {
"telegram_id": "123456789"
},
"metadata": {
"user_id": "user_123",
"plan": "premium"
}
}
}
Whatever you put in metadata comes right back. No more order matching headaches.

β’
Collecting entry fees via wallet transfers is chaotic
β’
Can't tell who actually paid until you check manually
β’
Sending prize money to 50+ winners takes hours
β’
Disputes over "I paid but didn't get registered"
β’
Spreadsheet hell for tracking payments
PAYchat solves all of this with a single API.
The Problem with Manual Methods
Manual Transfers | PAYchat | |
Entry fee tracking | Spreadsheets | Automatic |
Registration confirmation | Manual check | Webhooks |
Prize distribution | One by one | Bulk API |
Participant disputes | Many | Almost none |
Payment records | Scattered | Dashboard |
A transfer is just "sending money." A payment is "completing a registration."
How It Works
Entry Fee Collection
Player clicks "Join Tournament" β Enters PIN in PAYchat β Payment complete β Webhook notifies your server β Player registered automatically
Prize Distribution
Tournament ends β Your server calls withdrawal API with winner list β USDT sent to all winners β Telegram notifications sent automatically
