Collect VietQR Payments in Telegram Bots with AgentPay

ServicesAI VN — Mon, 06 Jul 2026 00:13:45 +0000

The Problem: Getting Paid Through Telegram Is Messy

You've built a useful Telegram bot—maybe it sells online courses, takes café orders, or books freelance services. Your users love it. But when payment time comes, everything breaks down. You're manually sending payment screenshots, users are using unsafe third-party links, and nobody's sure if money actually arrived. You definitely don't want to hold customer funds in your own account (legal liability, licensing headaches). What you need is a way for your bot to generate a VietQR code pointing directly at your bank account, and then automatically confirm when the payment settles. That's where AgentPay VN comes in.

Why VietQR + AgentPay Is the Right Move

VietQR is Vietnam's national instant payment standard—every bank supports it, every Vietnamese smartphone has a QR scanner built-in, and users trust it because it uses their actual bank app. AgentPay VN is an MIT-licensed Python SDK that wraps the complexity away. It never touches your money (the QR points straight to your bank), and a real bank feed confirms settlement in seconds. No middleman fees, no foreign exchange hassles, no merchant account approval delays.

The magic is in three lines:

create_payment_request — generate a unique request tied to your bot order
send checkout_url — post the QR code to your user
await_settlement — block until the bank confirms payment

That's it. Let's build it.

Installation and Setup

Step 1: Install the SDK

pip install agentpay-vn

Verify it works:

python -c "import agentpay; print(agentpay.__version__)"

Step 2: Set Up Your Bank Feed (One-Time)

AgentPay needs a way to know when your bank receives money. You'll configure a webhook or use AgentPay's bank integration partner. Visit https://agentpay.servicesai.vn/v1/docs for your bank's specific setup—most Vietnamese banks (Vietcombank, Techcombank, Agribank, etc.) are already supported.

Step 3: Get Your API Credentials

AGENTPAY_API_KEY — your secret key
AGENTPAY_MERCHANT_ID — identifies your account
TELEGRAM_BOT_TOKEN — from BotFather

Store these in a .env file (never commit it):

AGENTPAY_API_KEY=your_key_here
AGENTPAY_MERCHANT_ID=your_merchant_id
TELEGRAM_BOT_TOKEN=your_bot_token

Building Your First Payment Flow

Full Working Example: Course Sales Bot

Let's say you're selling a "Python Mastery" course for 299,000 VND via Telegram. Here's the complete flow:

import asyncio
from telegram import Update, InlineKeyboardButton, InlineKeyboardMarkup
from telegram.ext import Application, CommandHandler, ContextTypes
from agentpay import AgentPayClient, PaymentRequest
import os
from dotenv import load_dotenv

load_dotenv()

# Initialize AgentPay
client = AgentPayClient(
    api_key=os.getenv("AGENTPAY_API_KEY"),
    merchant_id=os.getenv("AGENTPAY_MERCHANT_ID")
)

app = Application.builder().token(os.getenv("TELEGRAM_BOT_TOKEN")).build()

# Store pending payments in memory (use Redis in production)
pending_payments = {}

async def start_course_purchase(update: Update, context: ContextTypes.DEFAULT_TYPE):

    User sends /buy_course — we create a payment request
    """
    user_id = update.effective_user.id
    course_price = 299000  # VND
    course_name = "Python Mastery 2024"

    # Step 1: Create a payment request with AgentPay
    payment_request = await client.create_payment_request(
        amount=course_price,
        description=f"Course: {course_name}",
        order_id=f"course_{user_id}_{int(asyncio.get_event_loop().time())}",
        customer_name=update.effective_user.full_name or "Anonymous",
        customer_phone="",  # Optional; collect if needed
        redirect_url="https://t.me/your_bot_username"  # Where to send user after payment

    # Step 2: Store the payment request locally (for later confirmation)
    pending_payments[payment_request.order_id] = {

    )

    await update.message.reply_text(
        f"🎓 Ready to buy **{course_name}**?\n\n"
        f"Price: **{course_price:,} VND**\n\n"
        f"Click the button below to scan the QR code with your bank app. "
        f"You'll be redirected back here once payment is confirmed.",

        parse_mode="Markdown"
    )

    # Step 4 (Background): Wait for settlement
    asyncio.create_task(wait_for_payment(payment_request.order_id, user_id, course_name))

async def wait_for_payment(order_id: str, user_id: int, course_name: str):
    """

if __name__ == "__main__":
    app.run_polling()

Line-by-line explanation:

Lines 10-14: Initialize AgentPayClient with your credentials.
Lines 23-39: create_payment_request() generates a unique payment link tied to this user's order.
Lines 42-44: Store the order locally so we can track who paid for what.
Lines 46-54: Build a Telegram inline button linking to the checkout URL (which displays the VietQR code).
Lines 57: Kick off a background task to wait for settlement—the user doesn't have to stay in the chat.
Lines 62-86: await_settlement() polls the bank feed until payment is confirmed. Once confirmed, we grant course access.
Lines 88-105: Optional /check_payment command lets users manually check if payment went through.

Using AgentPay with Claude and MCP

If you're using AI agents (Claude, etc.) to manage your bot, AgentPay provides an MCP (Model Context Protocol) server. Install it:

pip install agentpay-mcp

Configure it in your Claude settings (or .mcp.json):

{
  "mcpServers": {
    "agentpay": {
      "command": "python",
      "args": ["-m", "agentpay_mcp.server"],
      "env": {
        "AGENTPAY_API_KEY": "your_api_key",
        "AGENTPAY_MERCHANT_ID": "your_merchant_id"
      }
    }
  }
}

Now Claude can call AgentPay functions directly:

User: "A customer wants to buy my e-book for 99,000 VND. Create a payment link."

Claude: I'll use AgentPay to create a payment request for you.
[Calls: create_payment_request(amount=99000, description="E-book", ...)]
→ Returns checkout_url

Claude: "Here's your payment link: [link]. Share it with your customer."

Real-World Walkthrough: Café Ordering Bot

Imagine a small coffee shop in Saigon. They built a Telegram bot where customers can order coffee, pay, and pick up. Here's how AgentPay fits:

Order placed: Customer types /order → selects "2x Cà Phê Đen + 1x Trà Lạnh" (120,000 VND).
Payment link sent: Bot calls create_payment_request() → generates VietQR code → sends link to customer.
Customer scans: User opens their Agribank/Vietcombank app → scans QR → confirms transfer.
Settlement confirmed: Bank webhook hits AgentPay → await_settlement() resolves → bot sends "Order ready! Pick up at counter #3."
Record kept: Shop owner can see all payments in their AgentPay dashboard (linked to their actual bank statement).

Total time: 2 minutes. No middle app, no fees beyond normal bank transfer, no fraud risk.

Do's and Don'ts

✅ Do	❌ Don't
Use `.env` files for secrets	Hardcode API keys in source code
Implement retry logic on timeouts	Assume QR codes are unique per user (they're not—reuse is safe)
Log transaction IDs for reconciliation	Hold customer funds in a separate account
Set reasonable timeouts (5–30 min)	Use old/revoked QR codes
Test with small amounts first	Ignore bank feed errors silently
Store order metadata (product, user, timestamp)	Forget to handle network disconnects

Advanced Tips

Tip 1: Batch Payments

If you're selling multiple items, don't create separate payment requests. Sum the total and create one request:

total = sum([item["price"] for item in cart])
await client.create_payment_request(
    amount=total,
    description=f"{len(cart)} items",
    order_id=f"cart_{user_id}_{timestamp}"
)

Tip 2: Idempotency

If your bot crashes mid-payment, reuse the same order_id to avoid double-charging:

order_id = f"course_{user_id}_{course_id}"  # Deterministic
settlement = await client.get_payment_status(order_id)
if settlement and settlement.status == "confirmed":
    # Already paid—grant access
    pass
else:
    # Create new request
    await client.create_payment_request(order_id=order_id, ...)

Tip 3: Webhooks Instead of Polling

For production bots with thousands of users, polling is inefficient. Configure a webhook with AgentPay:

@app.post("/agentpay/webhook")
async def handle_settlement(payload: dict):
    order_id = payload["order_id"]
    status = payload["status"]

    if status == "confirmed":
        user_id = pending_payments[order_id]["user_id"]
        await app.bot.send_message(user_id, "✅ Payment confirmed!")

This way, AgentPay notifies you when payment settles—no polling required.

FAQ

Q: Does AgentPay hold my money?
No. The VietQR code points directly to your bank account. AgentPay only confirms settlement via your bank feed—it never touches the funds.

Q: What if a customer disputes the payment?
AgentPay logs all transactions with bank-confirmed transaction IDs. Disputes go through your bank's normal chargeback process—AgentPay provides the proof.

Q: Can I use AgentPay outside Vietnam?
Currently, VietQR is Vietnam-only. If you want to accept international payments, you'll need a separate solution (Stripe, PayPal).

Q: How long does settlement confirmation take?
Typically 2–10 seconds after the customer completes the transfer. Occasionally up to 2 minutes depending on the bank.

Q: Do I need to register my bot with the government?
Regulations vary. For educational or small commercial bots, you're usually fine. For large-scale commerce, consult a Vietnamese lawyer about merchant licensing.

Key Takeaways

VietQR + AgentPay = friction-free payments in Telegram bots without holding customer funds.
Installation is one line: pip install agentpay-vn
The flow is simple: create_payment_request() → send checkout_url() → await_settlement()
Bank confirmation is real: Your bank feed confirms every transaction—no fake payments.
Works at scale: Use webhooks for thousands of concurrent users; use polling for hobby bots.
MIT licensed & open-source: Full transparency, no vendor lock-in.
Vietnam-specific: Built for VietQR, integrated with major Vietnamese banks.

Agent-native payments: building idempotent checkout flows with AgentPay

ServicesAI VN — Thu, 25 Jun 2026 04:04:22 +0000

Problem: AI agents need to collect money without holding it

When Claude or another LLM agent needs to collect a payment—say, to unlock premium features or settle a service charge—most solutions require:

Complex integrations (Stripe, PayPal APIs with credential management)
Trust trade-offs (money sitting in escrow or a third-party account)
State management headaches (tracking payment status across agent runs)

Vietnam's VietQR ecosystem is perfect for this: QR codes point directly at merchant bank accounts. But there was no agent-native SDK until now.

How AgentPay solves it

AgentPay VN is an open-source (MIT) Python SDK + MCP server that:

Never touches money — QR codes point straight to your bank account
Confirms settlement by reading your SePay bank feed (one API key)
Supports idempotency — safe to retry without double-charging
Ships webhooks — your agent can await payment without polling

The flow is 3 lines:

from agentpay import PaymentClient

client = PaymentClient(api_key="your_key")

# Create a payment request
request = client.create_payment_request(
    amount=100000,  # VND
    description="Premium feature unlock",
    idempotency_key="user_123_2024_01_15"
)

print(f"Checkout: {request.checkout_url}")

# Await settlement (blocks until paid or timeout)
receipt = client.await_settlement(
    request_id=request.id,
    timeout=300  # 5 minutes
)

if receipt:
    print(f"Paid! Transaction: {receipt.transaction_id}")
else:
    print("Payment not received")

Wiring it into Claude via MCP

Install the MCP server:

pip install agentpay-vn

Add to claude_desktop_config.json:

{
  "mcpServers": {
    "agentpay": {
      "command": "agentpay-mcp",
      "env": {
        "AGENTPAY_API_KEY": "your_api_key",
        "AGENTPAY_ACCOUNT_ID": "your_account_id"
      }
    }
  }
}

Now in Claude:

User: "Lock my export feature behind a $5 payment."

Claude: Calls agentpay_create_payment → sends VietQR checkout URL → calls agentpay_await_settlement → confirms and unlocks feature.

Idempotency + webhooks matter

Idempotent requests prevent accidental double-charges if your agent retries:

# Same idempotency_key = same request, no duplicate charge
request = client.create_payment_request(
    amount=50000,
    idempotency_key="order_abc_retry_1"
)

Webhooks let you skip polling:

# Instead of await_settlement (blocking),
# configure a webhook in dashboard
# and handle POST at your endpoint

Honest limitations

VietQR only — Vietnam domestic payments. Not global.
SePay bank feed dependency — needs your bank to expose transaction data (Techcombank, VCB, BIDV support confirmed).
Settlement delay — typically 1-2 hours via SePay API.
No dispute resolution — you're responsible for refunds (it's a QR code, not a payment processor).

Collect VietQR Payments in Telegram Bots with AgentPay

ServicesAI VN — Tue, 16 Jun 2026 00:54:36 +0000

The Problem: Why Telegram Bots Struggle With Vietnamese Payments

You've built a Telegram bot that sells digital courses, coffee subscriptions, or online services to Vietnamese customers. Sales are coming in—but payments? That's where everything breaks down.

Payment processors like Stripe have high fees (2.9% + $0.30 per transaction). International gateways impose currency conversion taxes. Bank transfer instructions are manual and error-prone. Worst of all, you're juggling multiple systems: one for the bot, another for payment processing, another for settlement confirmation.

By the time a customer clicks "Buy," you've lost them to friction.

VietNam's VietQR system solves this elegantly—it's instant, built into every smartphone banking app, and costs nearly nothing. But integrating it into a Telegram bot? That's been the missing piece. Until now.

What AgentPay Does (And Doesn't)

AgentPay VN is an open-source Python SDK + MCP server that bridges Telegram bots to VietQR payments. Here's the critical distinction: AgentPay never touches your money. It generates a QR code that points directly to your merchant bank account. When a customer scans and pays, their bank confirms settlement to your system.

This means:

Zero fraud risk on your end (you're not a payment intermediary)
Instant settlement (no waiting 3–5 business days)
Transparent fees (only your bank's standard rates apply)
MIT-licensed (you own the integration, no vendor lock-in)

The tech stack: Python SDK for payment orchestration, an MCP server for AI agent integration, and bank feed confirmation for settlement verification.

Installation and Setup

Step 1: Install the SDK

Open your terminal and run:

pip install agentpay-vn

This installs the core SDK. If you're running an MCP-enabled AI system (Claude, or custom agents), also install:

pip install agentpay-mcp

Step 2: Initialize Your Credentials

Create a .env file in your project root:

MERCHANT_BANK_ACCOUNT=0123456789
MERCHANT_BANK_NAME=Vietcombank
MERCHANT_NAME=Your Business Name
API_KEY=your_api_key_from_dashboard

Retrieve these from the AgentPay dashboard at https://agentpay.servicesai.vn/v1/docs.

Step 3: Import and Test

Create a file payment_test.py:

from agentpay_vn import AgentPayClient
import os
from dotenv import load_dotenv

load_dotenv()

client = AgentPayClient(
    api_key=os.getenv("API_KEY"),
    merchant_account=os.getenv("MERCHANT_BANK_ACCOUNT"),
    merchant_bank=os.getenv("MERCHANT_BANK_NAME"),
    merchant_name=os.getenv("MERCHANT_NAME")
)

print("AgentPay initialized successfully!")

Run it: python payment_test.py. You should see the success message.

send_checkout(): The /buy command creates a payment and sends the customer a Telegram message with the VietQR link. They scan it with their banking app and complete the transfer in seconds.
verify_payment() / await_settlement(): Polls AgentPay's bank feed confirmation. When the customer's bank confirms the transfer to your merchant account, the SDK returns SETTLED. You then unlock their access.

MCP Server Configuration for AI Agents

If you're running Claude or another MCP-compatible AI, configure it to use AgentPay tools:

{
  "mcpServers": {
    "agentpay": {
      "command": "python",
      "args": ["-m", "agentpay_mcp"],
      "env": {
        "AGENTPAY_API_KEY": "your_api_key",
        "MERCHANT_ACCOUNT": "0123456789",
        "MERCHANT_BANK": "Vietcombank",
        "MERCHANT_NAME": "Your Business"
      }
    }
  }
}

Save this as .claude.json (if using Claude Desktop). The AI can now invoke create_payment_request and await_settlement as native tools—perfect for automating payment flows in conversational UIs.

Real-World Scenario: Café Pre-Order Bot

Let's walk through a concrete use case.

The Setup:
An espresso café in Ho Chi Minh City runs a Telegram bot where customers pre-order coffee for pickup. Current problem: they manually request bank transfers, which is chaotic and error-prone.

With AgentPay:

Customer messages /preorder → bot sends menu
Customer selects "2× Cappuccino + 1× Iced Tea" (125,000 VND)
Bot calls create_payment_request() and sends VietQR checkout link
Customer scans QR in their bank app, completes transfer in 10 seconds
Bot's await_settlement() detects the payment (usually within 30 seconds)
Order automatically printed in the café kitchen
Customer gets a notification: "Ready for pickup in 10 minutes!"

The numbers:

Traditional bank transfer: 5–10 minutes of manual back-and-forth
AgentPay flow: 30–60 seconds end-to-end
Cost: ~0% (vs. 2–3% with Stripe)
Customer experience: 100% frictionless

Do's and Don'ts

✅ Do	❌ Don't
Store `payment_id` in your database for audit trails	Try to "reverse" or "refund" payments—use your bank's tools
Set `timeout=600` (10 min) for settlement polling	Wait indefinitely; always have a timeout to prevent bot hangs
Include meaningful `metadata` (course_id, user_id) for tracking	Expose your `API_KEY` in client-side code; keep it server-side only
Test with small amounts (1,000–5,000 VND) first	Assume `await_settlement()` is instant; add 5–10 second polling intervals
Use `/v1/docs` to verify your merchant account is active	Store customer bank details—AgentPay never asks for them

Advanced Tips

Idempotency: Prevent Double Charges

Network hiccups can cause duplicate requests. Use idempotency keys:

import uuid

idempotency_key = str(uuid.uuid4())
payment = await client.create_payment_request(
    amount=49000,
    description="Course",
    user_reference=user_id,
    idempotency_key=idempotency_key  # Same key = same payment_id
)

Retry Logic for Settlement Polling

Network glitches can interrupt polling. Add exponential backoff:

import random

async def verify_payment_with_retry(payment_id: str, max_retries: int = 5):
    for attempt in range(max_retries):
        try:
            status = await client.await_settlement(payment_id, timeout=10)
            return status["status"] == PaymentStatus.SETTLED
        except Exception as e:
            wait_time = 2 ** attempt + random.uniform(0, 1)
            print(f"Retry {attempt + 1}/{max_retries} after {wait_time:.1f}s")
            await asyncio.sleep(wait_time)
    return False

Webhook Alternative (Optional)

Instead of polling, AgentPay can POST to your webhook when payment settles:

payment = await client.create_payment_request(
    amount=49000,
    description="Course",
    user_reference=user_id,
    webhook_url="https://yourbot.com/payment-webhook"  # Receives POST when settled
)

FAQ

Q: What happens if a customer doesn't pay within 10 minutes?
A: The payment request expires and a new one must be created. The old QR code becomes inactive. This is by design to prevent accidental old-payment rescans.

Q: Can I refund a payment?
A: AgentPay doesn't handle refunds—you do, via your bank app. The customer's money goes directly to your account. This is a feature, not a bug: you're in control, not a third party.

Q: Does AgentPay work with international customers?
A: Only for customers with Vietnamese VietQR-enabled bank accounts. The QR standard doesn't support cross-border transfers yet.

Q: What if the bot goes offline during settlement polling?
A: Use webhooks (above) instead of polling. Or store pending payments in a database and resume polling when the bot restarts.

VietQR Payments for AI Agents—No Stripe Setup

ServicesAI VN — Sun, 14 Jun 2026 04:26:00 +0000

VietQR Payments for AI Agents—No Stripe Setup

The Problem

Building AI agents in Vietnam that need to collect payments? Stripe doesn't support VietQR, and integrating traditional payment gateways means managing API keys, webhooks, and fund settlement delays. Most solutions require your agent to hold or route money through intermediaries.

What if your AI could generate a QR code that points directly to your business bank account?

Introducing AgentPay VN

AgentPay is an open-source (MIT) Python SDK + MCP server that lets Claude, local LLMs, and custom agents collect VietQR payments in three lines of logic:

Create a payment request
Send the checkout URL to your customer
Await settlement confirmation from the bank feed

No middleman. No fund holding. The QR points straight to your merchant account.

How It Works

AgentPay reads your bank's SePay feed to confirm when a payment settles. It doesn't touch the money—it just watches for it. Your AI agent can then trigger downstream workflows (send invoice, unlock feature, etc.) once settlement is confirmed.

Installation

pip install agentpay-vn

Or run the MCP server for Claude Desktop / Code:

pip install agentpay-mcp

Quick Example

from agentpay import AgentPayClient

client = AgentPayClient(
    api_key="your_api_key",
    merchant_id="your_merchant_id"
)

# Step 1: Create payment request
payment = client.create_payment_request(
    amount=100000,  # 100K VND
    description="AI consulting session",
    order_id="order_12345"
)

print(f"Checkout URL: {payment.checkout_url}")
# Share with customer → they scan QR → money hits your bank

# Step 2: Poll for settlement
import time
while True:
    status = client.get_payment_status(payment.id)
    if status.settled:
        print("✓ Payment confirmed! Triggering downstream workflow...")
        break
    time.sleep(5)

MCP Integration

Add to your Claude Desktop config (claude_desktop_config.json):

{
  "mcpServers": {
    "agentpay": {
      "command": "python",
      "args": ["-m", "agentpay_mcp.server"],
      "env": {
        "AGENTPAY_API_KEY": "your_api_key",
        "AGENTPAY_MERCHANT_ID": "your_merchant_id"
      }
    }
  }
}

Now Claude can:

Generate payment QR codes on demand
Check settlement status mid-conversation
Chain payments into multi-step workflows

Real Use Cases

AI Consulting Chatbots: "That analysis will cost ₫500K. [Scan QR]. Thanks! Here's your report."
Autonomous Trading Bots: Collect fees when trades execute; settle directly to ops account.
AI Content Marketplace: Agent lists content, collects micro-payments, splits revenue—all via QR.

Honest Limitations

Vietnam-only: Requires a VietQR-compatible bank account.
SePay dependency: Settlement confirmation relies on your bank's SePay feed API (not all banks fully supported yet—check docs).
Polling model: No real-time webhooks; you'll poll for status updates.
Early-stage: Open-source project; production use should include your own monitoring.
