Quick Start

1. Install

# No pip install needed — just copy the aba_sdk/ folder into your project.
# Or install from this repo:
pip install -e .

2. Configure

from aba_sdk import PayWayClient, PayWayConfig, Environment

config = PayWayConfig(
    merchant_id="your_merchant_id",
    api_key="your_api_key",
    env=Environment.sandbox,   # OR Environment.production
)
client = PayWayClient(config)

3. Generate a QR Code

from aba_sdk.models import QRRequest, Currency, PaymentOption
from aba_sdk.utils import encode_items, encode_url
from aba_sdk.utils.timestamp import get_req_time


request = QRRequest(
    tran_id=tran_id = f"ORDER-{get_req_time()}",
    amount=8.00,
    currency=Currency.USD,      # Supported KHR, USD
    payment_option=PaymentOption.ABAPAY_KHQR,
    first_name="Khon",
    last_name="Chanphearaa",
    email="phearaa@example.com",
    phone="012345678",

    # Optional
    items=encode_items([
        {"name": "Coffee", "quantity": 2, "price": 2.50},
        {"name": "Sandwich", "quantity": 1, "price": 3.00},
    ]),
    callback_url=encode_url("https://yoursite.com/payway/callback"),
    lifetime=6,
)

response = client.qr.generate_qr(request)

print(response.qr_string)           # Raw KHQR string
print(response.abapay_deeplink)     # Deep link for ABA Mobile
response.save_qr_image("qr.png")    # Save Base64 PNG to disk

---

Error Handling

from aba_sdk import PayWayAPIError, PayWayRequestError

try:
    response = client.qr.generate_qr(request)
except PayWayAPIError as e:

    # API returned an error (wrong domain, invalid hash, etc.)
    print(f"[{e.code}] {e.message}  trace={e.trace_id}")
except PayWayRequestError as e:

    # Network timeout or connection error
    print(f"Network error: {e}")

Extending the SDK

Each API group gets its own file in aba_sdk/api/ and its own models in aba_sdk/models/. Then register the new client in PayWayClient:

# aba_sdk/client.py
from .api.checkout import CheckoutClient   # new module

class PayWayClient:
    def __init__(self, config):
        self.qr = QRClient(config)
        self.checkout = CheckoutClient(config)   # add here

• Generate QRCode
• Check Transaction
