## 🚀 Usage

The bakong-khqr package provides the KHQR class for generating QR code, Deeplink, Check Payment, Get Payment transaction for Bakong KHQR.

### Importing the package

You can import the KHQR class from the package as follows:

```bash
from bakong_khqr import KHQR
```

### Creating Payment Transaction

To generate QR code data for a transaction, create an instance of the KHQR() class with Bakong Token and call the:

- create_qr() method with the required parameters.
- generate_deeplink() method with the required parameters.
- generate_md5() method with the required parameters.
- check_payment() method with the required parameters.
- get_payment() method with the required parameters.
- check_bulk_payments() method with the required parameters.

Example:

```bash
from bakong_khqr import KHQR

# Create an instance of KHQR with Bakong Developer Token:
khqr = KHQR("eyJhbGciOiJIUzI1NiIsI...nMhgG87BWeDg9Lu-_CKe1SMqC0")

# Generate QR code data for a transaction:
qr = khqr.create_qr(
    bank_account='user_name@bank', # Check your user_name@bank under Bakong profile (Mobile App)
    merchant_name='Your Name',
    merchant_city='Phnom Penh',
    amount=9800, #9800 Riel
    currency='KHR', # USD or KHR
    store_label='Phsar Thmei',
    phone_number='012345678',
    bill_number='TRX012345',
    terminal_label='POS-01',
    static=False, # Static or Dynamic QR code (default: False)
    expiration=1 # Expiration time in 1 day for the QR code (default: 1 day). This is used to calculate the expiration time for the QR code.
)
print(qr)
# String Result: 00020101021229180014your_name@bank520459995303116540498005802KH5909Your Name6010Phnom Penh62510109TRX01234502090123456780311Phsar Thmei0706POS-01993400131773894603019011317738947758196304A5A3

# Generate Deeplink:
deeplink = khqr.generate_deeplink(
    qr,
    callback="https://your_website.com/shop/details?q=ABC", # Or your app's custom scheme (e.g., mshop://purchase/39482)
    appIconUrl="https://your_website.com/images/logo.png", # Your logo image .png or .svg
    appName="MyAppName" # (e.g., MSHOP)
)
print(deeplink)
# String Result: https://bakong.page.link/CgXb....ks6az9a38

# Get Hash MD5
md5 = khqr.generate_md5(qr)
print(md5)
# String Result: dfcabf4598d1c405a75540a3d4ca099d

# Check Transaction paid or unpaid:
payment_status = khqr.check_payment(md5)
print(payment_status)
# String Result: "UNPAID"
# Indicates that this transaction has not yet been paid.

# Retrieve the payment information:
#e.g. In case static QR code (static=True) is used for payment, and the amount is not known from the user's input.
payment_info = khqr.get_payment(md5)
print(payment_info)
# Object Result:
# {
#     "hash": "a7121ca103c.....eb3671b9601a6",
#     "fromAccountId": "bankkhppxxx@bank",
#     "toAccountId": "your_name@bank",
#     "currency": "KHR",
#     "amount": 9800,
#     "description": "Cashier-01",
#     "createdDateMs": 1739###953000,
#     "acknowledgedDateMs": 1739###954000,
#     "trackingStatus": null,
#     "receiverBank": null,
#     "receiverBankAccount": null,
#     "instructionRef": null,
#     "externalRef": "100FT3###6550298"
# }
# You can retrieve information such as the amount to integrate into your system.

# Check Bulk Transactions:
md5_list = [
    "dfcabf4598d1c405a75540a3d4ca099d", 
    "5154e4f795634ff1a0ae4b48e53a6d9c",
    "a57d9bb85f52f12a20cf7beecb03d11d",
    "495fdaec0be5d94c89bc1283c7283d3d",
    "31bca02094ad576588e42b60db57bc98"
]

bulk_payments_status = khqr.check_bulk_payments(md5_list)
print(bulk_payments_status)
# List Result: ["5154e4f795634ff1a0ae4b48e53a6d9c", "495fdaec0be5d94c89bc1283c7283d3d"]
# Returns a list containing only the MD5 hashes that correspond to successful (paid) transactions.


# ⚠️ Bulk Transaction Check Limit
# The Bakong API allows a maximum of 50 MD5 hashes per request when using the check_bulk_payments() method.
#If you pass more than 50 hashes, the function will raise a ValueError to prevent unexpected API errors.

md5_list = [md5_1, md5_2, ..., md5_51]  # 51 hashes

# This will raise:
# ValueError: The md5_list exceeds the allowed limit of 50 hashes per request.
result = khqr.check_bulk_payments(md5_list)

# ✅ If you need to check more than 50 transactions, you must handle chunking manually:
def chunked(iterable, size=50):
    for i in range(0, len(iterable), size):
        yield iterable[i:i + size]

all_md5 = [...]  # more than 50 md5 hashes
paid_md5 = []

for batch in chunked(all_md5):
    paid_md5.extend(khqr.check_bulk_payments(batch))

print(paid_md5)
# List Result: ["5154e4f795634ff1a0ae4b48e53a6d9c", "495fdaec0be5d94c89bc1283c7283d3d"]
# Returns a list containing only the MD5 hashes that correspond to successful (paid) transactions.
```

### Generate QR Image

The `qr_image()` method generates a QR code image from a QR string.
Make sure you install the optional [image] extras to get dependencies like Pillow and qrcode:

```bash
pip3 install "bakong-khqr[image]"
```

Example:

```bash
from bakong_khqr import KHQR

khqr = KHQR("your_bakong_token")

qr = khqr.create_qr(
    bank_account='user_name@bank',
    merchant_name='Your Name',
    merchant_city='Phnom Penh',
    amount=100.00,
    currency='USD',
    store_label='MShop',
    phone_number='85512345678',
    bill_number='TRX123456',
    terminal_label='Cashier-01',
    static=False,
    expiration=1
)

# Generate QR image as PNG file path
png_path = khqr.qr_image(qr)
print("QR image saved at:", png_path)

```

## ✨ Bakong Relay API Support (New in v0.5.*)
### Why Use Bakong Relay? (Optional)

Many developers face **HTTP 403 errors** when accessing Bakong APIs from servers outside Cambodia.

This service allows you to use **RBK tokens** directly in `bakong-khqr` (Python SDK), so your application can reliably check transactions, accounts, and references without restrictions.

**Important**: Only `bakong-khqr` (Python SDK) supports RBK tokens.

Using Bakong Relay is **optional**.  
If your server is in Cambodia or you have no access issues, you can continue using official Bakong tokens — no changes are needed.

For more information, token creation, pricing, and full documentation, visit:
