1. Tính năng chính

2. Cấu trúc module

2.1. Flow

2.2. Endpoint API

3. PAYMENT TRANSACTION MODEL

3.1. Define model

Model payment.online.transaction là model chính của module, quản lý toàn bộ thông tin giao dịch thanh toán.

class PaymentTransaction(models.Model):
    _name = "payment.online.transaction"
    _description = "Online Payment Transaction"
    _inherit = ["mail.thread", "mail.activity.mixin"]
    _order = "create_date desc"

    name = fields.Char(string="Mã giao dịch", required=True, readonly=True, default=lambda self: _("New"), copy=False)

    partner_id = fields.Many2one("res.partner", string="Khách hàng", required=True, tracking=True)

    amount = fields.Monetary(string="Số tiền", required=True, tracking=True)

    currency_id = fields.Many2one("res.currency", string="Tiền tệ", default=lambda self: self.env.company.currency_id)

    provider = fields.Selection([("stripe", "Stripe"), ("vnpay", "VNPAY")], string="Nhà cung cấp", required=True, default="stripe", tracking=True)

4. Tích hợp stripe

4.1. Giới thiệu

Stripe Checkout là giải pháp thanh toán hosted của Stripe, cung cấp giao diện thanh toán hoàn chỉnh, hỗ
trợ nhiều phương thức thanh toán và đa tiền tệ.
Ưu điểm:
Giao diện thanh toán đẹp, responsive
Hỗ trợ nhiều phương thức: Card, Apple Pay, Google Pay
PCI Compliance - không cần lưu thông tin thẻ
Hỗ trợ đa tiền tệ (135+ currencies)
Webhook đáng tin cậy

4.2 Cấu hình Stripe

class ResConfigSettings(models.TransientModel):
    _inherit = "res.config.settings"

    stripe_publishable_key = fields.Char(string="Stripe Publishable Key", config_parameter="online_paying.stripe_publishable_key")

    stripe_secret_key = fields.Char(string="Stripe Secret Key", config_parameter="online_paying.stripe_secret_key")

    stripe_webhook_secret = fields.Char(string="Stripe Webhook Secret", config_parameter="online_paying.stripe_webhook_secret")

    stripe_success_url = fields.Char(string="Stripe Success URL", config_parameter="online_paying.stripe_success_url")

    stripe_cancel_url = fields.Char(string="Stripe Cancel URL", config_parameter="online_paying.stripe_cancel_url")

4.3 Method: action_create_stripe_payment()

def action_create_stripe_payment(self):
    """Tạo yêu cầu thanh toán Stripe Checkout Session"""

    self.ensure_one()

    if self.provider != "stripe":
        raise UserError(_("Giao dịch này không phải thanh toán Stripe"))

    config = self._get_stripe_config()

    if not config["secret_key"]:

    # Stripe uses smallest currency unit
    currency_code = self.currency_id.name.lower() if self.currency_id else "usd"

    # Stripe requires amount in smallest currency unit
    if currency_code in ["vnd", "jpy", "krw"]:
        amount = int(self.amount)
    else:
        amount = int(self.amount * 100)

    order_info = self.description or f"Thanh toán đơn hàng {self.name}"

    payload = {
        "payment_method_types[]": "card",
        "line_items[0][price_data][currency]": currency_code,
        "line_items[0][price_data][product_data][name]": order_info,

        "metadata[odoo_transaction_name]": self.name,
    }

    if self.partner_id.email:
        payload["customer_email"] = self.partner_id.email

    try:

4.4 Xử lý Currency

Stripe yêu cầu số tiền phải truyền ở đơn vị nhỏ nhất của tiền tệ.

Tiền tệ Xử lý Ví dụ
USD, EUR, GBP ×100 (cents) $10.50 → 1050
VND, JPY, KRW Giữ nguyên 150,000đ → 150000

Ví dụ xử lý:

if currency_code in ["vnd", "jpy", "krw"]:
    amount = int(self.amount)
else:
    amount = int(self.amount * 100)

Enter fullscreen mode Exit fullscreen mode

Ví dụ:

  • 10.50 USD1050
  • 150000 VND150000
  • 2000 JPY2000

5: Tích hợp VNPAY

5.1 Tổng quan VNPAY

VNPAY là cổng thanh toán phổ biến tại Việt Nam, hỗ trợ:

  • 🏦 Internet Banking (40+ ngân hàng)
  • 💳 Thẻ nội địa (Napas)
  • 💳 Thẻ quốc tế (Visa, MasterCard, JCB, Amex)
  • 📱 Ví điện tử VNPAY

5.2 Cấu hình VNPAY

Thêm cấu hình vào res.config.settings

# VNPAY CONFIG

vnpay_tmn_code = fields.Char(
    string="VNPAY Terminal ID (vnp_TmnCode)",
    config_parameter="online_paying.vnpay_tmn_code",
    help="Mã website tại VNPAY"
)

vnpay_hash_secret = fields.Char(
    string="VNPAY Hash Secret (vnp_HashSecret)",
    config_parameter="online_paying.vnpay_hash_secret",
    help="Chuỗi bí mật tạo checksum"
)

vnpay_url = fields.Char(
    string="VNPAY Payment URL",
    config_parameter="online_paying.vnpay_url",
    default="https://sandbox.vnpayment.vn/paymentv2/vpcpay.html"
)

vnpay_return_url = fields.Char(
    string="VNPAY Return URL",
    config_parameter="online_paying.vnpay_return_url"
)

Enter fullscreen mode Exit fullscreen mode


5.3 Method: action_create_vnpay_payment()

def action_create_vnpay_payment(self):
    """Tạo yêu cầu thanh toán VNPAY"""

    self.ensure_one()

    import hashlib
    import hmac
    import urllib.parse
    from datetime import datetime, timedelta, timezone

    if self.provider != "vnpay":
        raise UserError(_("Giao dịch này không phải thanh toán VNPAY"))

    config = self._get_vnpay_config()

    if not config["tmn_code"] or not config["hash_secret"]:
        raise UserError(
            _("Chưa cấu hình đầy đủ thông tin VNPAY")
        )

    # VNPAY chỉ hỗ trợ VND
    if self.currency_id.name != "VND":
        raise UserError(_("VNPAY chỉ hỗ trợ thanh toán bằng VND"))

    vnp_txn_ref = f"{self.id}-{datetime.now().strftime('%Y%m%d%H%M%S')}"

    # VNPAY yêu cầu số tiền x100
    vnp_amount = int(self.amount * 100)

    order_info = self.description or f"Thanh toan don hang {self.name}"
    order_info = self._remove_diacritics(order_info)

    vn_tz = timezone(timedelta(hours=7))
    vn_now = datetime.now(vn_tz)

    vnp_create_date = vn_now.strftime("%Y%m%d%H%M%S")
    vnp_expire_date = (
        vn_now + timedelta(minutes=60)
    ).strftime("%Y%m%d%H%M%S")

    vnp_params = {
        "vnp_Version":"2.1.0",
        "vnp_Command":"pay",
        "vnp_TmnCode":config["tmn_code"],
        "vnp_Amount":str(vnp_amount),
        "vnp_CurrCode":"VND",
        "vnp_TxnRef":vnp_txn_ref,
        "vnp_OrderInfo":order_info,
        "vnp_OrderType":"other",
        "vnp_Locale":"vn",
        "vnp_ReturnUrl":config["return_url"],
        "vnp_IpAddr":"127.0.0.1",
        "vnp_CreateDate":vnp_create_date,
        "vnp_ExpireDate":vnp_expire_date
    }

Enter fullscreen mode Exit fullscreen mode

Tiếp theo tạo chữ ký:

sorted_params = sorted(vnp_params.items())

hash_data = "&".join([
    f"{urllib.parse.quote_plus(str(k))}={urllib.parse.quote_plus(str(v))}"
    for k, v in sorted_params
])

secure_hash = hmac.new(
    config["hash_secret"].encode("utf-8"),
    hash_data.encode("utf-8"),
    hashlib.sha512
).hexdigest()

Enter fullscreen mode Exit fullscreen mode

Build payment URL:

query_string = urllib.parse.urlencode(sorted_params)

payment_url = (
    f"{config['vnpay_url']}?"
    f"{query_string}"
    f"&vnp_SecureHash={secure_hash}"
)

self.write({
    "state":"pending",
    "request_id":vnp_txn_ref,
    "payment_url":payment_url
})

return {
    "type":"ir.actions.act_url",
    "url":payment_url,
    "target":"new"
}

Enter fullscreen mode Exit fullscreen mode


5.4 Thuật toán tạo chữ ký VNPAY

INPUT:
- vnp_params
- hash_secret

STEP 1:
Sort parameters alphabetically

STEP 2:
Build hash string

key1=value1&key2=value2...

(URL encode key + value)

STEP 3:
Generate SHA512 HMAC

secure_hash = HMAC_SHA512(
    hash_secret,
    hash_data
)

STEP 4:
Return secure_hash.hexdigest()

Enter fullscreen mode Exit fullscreen mode


5.5 Xử lý dấu tiếng Việt

VNPAY không hỗ trợ Unicode trong vnp_OrderInfo.

Ví dụ:

"Thanh toán đơn hàng"
↓
"Thanh toan don hang"

Enter fullscreen mode Exit fullscreen mode

Implementation:

def _remove_diacritics(self, text):
    """Remove Vietnamese diacritics"""

    import unicodedata
    import re

    text = unicodedata.normalize("NFD", text)

    text = re.sub(
        r'[\u0300-\u036f]',
        '',
        text
    )

    text = (
        text.replace('đ','d')
        .replace('Đ','D')
    )

    return text

Enter fullscreen mode Exit fullscreen mode


5.6 Mã lỗi VNPAY

07 Giao dịch nghi ngờ
09 Chưa đăng ký Internet Banking
10 Xác thực sai quá 3 lần
11 Hết hạn thanh toán
12 Tài khoản bị khóa
