fawaterak

Unofficial Python SDK for the Fawaterak API.

This project is not affiliated with, endorsed by, or sponsored by Fawaterak. It is a community-maintained, unofficial SDK written by independent developers. The maintainers have no business relationship with the company Fawaterak. Use this library at your own risk.

Status

This project is in early development (0.4.0). The foundational OAuth/HTTP layers, the core transaction client (payment methods, create/fetch/list transactions), the framework-agnostic webhook verification/parsers, and e-invoicing are implemented. Refunds and tokenization are still on the roadmap.

Features

• Explicit configuration via constructor arguments or environment variables.

• OAuth2 token management (client_credentials + refresh_token flows) with automatic caching and expiry-aware renewal.

• Thread-safe token refresh so concurrent callers do not issue duplicate /oauth/token requests.

• Central HTTP client with bearer-token injection, transport-level retries, and Fawaterak-specific error mapping.

• Exception hierarchy for network, authentication, validation, and transient API errors.

• FawaterakClient with get_payment_methods, create_transaction, get_transaction, and list_transactions covering the core transaction flow.

• E-invoicing with create_einvoice, get_einvoice, list_einvoices, update_einvoice, and delete_einvoice for shareable, multi-attempt payment links.

• Webhook verification and parsing with HMAC signature checks and typed

  event dataclasses (PaidWebhookEvent, FailedWebhookEvent, CancelWebhookEvent, RefundWebhookEvent).

• Two transaction modes — hosted checkout (result.url) and direct payment (result.payment_data), with a discriminated PaymentResult union for card redirects, reference codes (Fawry/Aman/Masary), and mobile wallets.

• Typed dataclass models (Customer, CartItem, TransactionData, Page, etc.) that serialize to the exact API payload shapes.

Installation

pip install fawaterak

Or with uv:

uv add fawaterak

Quick start

from fawaterak import Config, FawaterakClient

conf = Config.resolve(
	client_id="your-client-id",
	client_secret="your-client-secret",
	environment="staging",  # or "production"
)

client = FawaterakClient(config=conf)
methods = client.get_payment_methods()
print([method.name_en for method in methods])

Configuration

Config.resolve() accepts explicit arguments and falls back to environment variables. Explicit arguments always win.

* Either environment (staging or production) or a direct base_url must be provided.

** Must be provided if you plan to use Webhooks.

Usage

Hosted checkout

Omit payment_method_id to create a payment link and redirect the customer to the Fawaterak-hosted checkout page.

from fawaterak import CartItem, Customer, RedirectionUrls

result = client.create_transaction(
	currency="EGP",
	customer=Customer(
		first_name="Ahmed",
		last_name="Ali",
		email="ahmed@example.com",
	),
	cart_items=[CartItem(name="Order total", price=100.0, quantity=1)],
	cart_total=100.0,
	redirection_urls=RedirectionUrls(
		success_url="https://yoursite.com/success",
		fail_url="https://yoursite.com/fail",
	),
)

# result is a HostedCheckoutResult
redirect_url = result.url

Direct payment

Pass a payment_method_id from get_payment_methods() to pay with a specific method. The response returns provider-specific data in result.payment_data.

result = client.create_transaction(
	currency="EGP",
	customer=Customer(first_name="Ahmed", last_name="Ali"),
	cart_items=[CartItem(name="Order total", price=100.0, quantity=1)],
	cart_total=100.0,
	payment_method_id=3,  # e.g. Fawry
)

from fawaterak import (
	CardPaymentResult,
	MobileWalletResult,
	ReferenceCodeResult,
)

payment = result.payment_data
if isinstance(payment, ReferenceCodeResult):
	print(payment.reference_number)
elif isinstance(payment, CardPaymentResult):
	print(payment.redirect_to)
elif isinstance(payment, MobileWalletResult):
	print(payment.iso_qr)

Fetch and list transactions

from datetime import date

transaction = client.get_transaction("550e8400-e29b-41d4-a716-446655440000")
print(transaction.status_text)

page = client.list_transactions(
	start_date=date(2026, 1, 1),
	end_date=date(2026, 1, 31),
	per_page=15,
)
for item in page.data:
	print(item.transaction_id, item.status_text)

E-invoicing

Create and manage multi-attempt payment links. The customer can pay at any time within the due date and retry with different payment methods.

from fawaterak import CartItem, Customer
from datetime import date

# Create an e-invoice (requires customer_unique_id)
created = client.create_einvoice(
	currency="EGP",
	customer=Customer(
		first_name="Ahmed",
		last_name="Ali",
		customer_unique_id="user_12345",
	),
	cart_items=[CartItem(name="Order total", price=100.0, quantity=1)],
	cart_total=100.0,
)
print(created.url)  # hosted payment link

# Fetch, list, update, and delete
invoice = client.get_einvoice(created.invoice_id)

page = client.list_einvoices()
for item in page.data:
	print(item.invoice_id, item.status)

# Replace line items (default; requires currency + products)
updated = client.update_einvoice(
	invoice_id=created.invoice_id,
	customer=Customer(
		first_name="Ahmed",
		last_name="Ali",
		customer_unique_id="user_12345",
	),
	currency="EGP",
	products=[CartItem(name="Updated item", price=200.0, quantity=2)],
)

# Update metadata only, preserving existing line items
metadata = client.update_einvoice(
	invoice_id=created.invoice_id,
	customer=Customer(
		first_name="Ahmed",
		last_name="Ali",
		customer_unique_id="user_12345",
	),
	has_history=True,
	invoice_number="INV-001",
	tags="monthly",
)

client.delete_einvoice(created.invoice_id)

has_history=True tells the API to skip currency/product validation and keep the existing line items, so you can update fields like invoice_number or tags without resending the cart.

Webhooks

The SDK verifies webhook HMAC signatures using your vendor API key (not the OAuth client secret). It is framework-agnostic: parse the incoming body into a dict using your web framework, then call the provided parser.

Flask example (paid webhook)

from fawaterak import FawaterakClient

client = FawaterakClient()


@app.post("/webhooks/fawaterak/paid/")
def handle_paid_webhook():
	payload = request.get_json() or request.form.to_dict()
	event = client.parse_paid_webhook(payload)

	if event.status == "paid":
		fulfill_order(event)

	return "OK", 200

Django example

from django.http import JsonResponse
from django.views.decorators.csrf import csrf_exempt
from fawaterak import FawaterakClient

client = FawaterakClient()


@csrf_exempt
def fawaterak_paid_webhook(request):
	payload = request.POST if request.method == "POST" else request.json()
	event = client.parse_paid_webhook(payload)

	if event.status == "paid":
		fulfill_order(event)

	return JsonResponse({"status": "ok"})

FastAPI example

from fastapi import FastAPI, Request
from fawaterak import FawaterakClient

app = FastAPI()
client = FawaterakClient()


@app.post("/webhooks/fawaterak/paid/")
async def handle_paid_webhook(request: Request):
	payload = await request.json()
	event = client.parse_paid_webhook(payload)

	if event.status == "paid":
		fulfill_order(event)

	return {"status": "ok"}

Other webhook types

# Failed payment
failed_event = client.parse_failed_webhook(payload)

# Cancelled / expired reference
cancel_event = client.parse_cancel_webhook(payload)

# Refund approved
refund_event = client.parse_refund_webhook(payload)

# Dispatch by type when the endpoint handles multiple webhook kinds
from fawaterak.webhooks import WebhookType

event = client.parse_webhook(payload, WebhookType.REFUND)

You can also call the standalone functions in fawaterak.webhooks directly if you prefer not to instantiate FawaterakClient for webhook handlers.

Paid and failed webhooks can be delivered as JSON or form-urlencoded; cancel and refund webhooks are always JSON. The parsers raise FawaterakWebhookException if the signature does not match. The generic verify_webhook/parse_webhook dispatchers raise FawaterakWebhookException for unknown webhook types.
