Craftgate Python Client

This repo contains the Python client for Craftgate API.

PyPI package: https://pypi.org/project/craftgate/

Requirements

• Python 3.6+

Installation

pip install craftgate

Usage

To access the Craftgate API you'll first need to obtain API credentials (API key & secret key). If you don't already have a Craftgate account, you can sign up at https://craftgate.io.

By default the client connects to production https://api.craftgate.io. For testing, use the sandbox URL https://sandbox-api.craftgate.io.

from craftgate import Craftgate, RequestOptions

options = RequestOptions(
    api_key="<YOUR API KEY>",
    secret_key="<YOUR SECRET KEY>",
    base_url="https://sandbox-api.craftgate.io"
)
payment = Craftgate(options).payment()

Example: Credit Card Payment

import uuid
from decimal import Decimal

from craftgate import Craftgate, RequestOptions
from craftgate.model import Currency, PaymentGroup, PaymentPhase
from craftgate.request import CreatePaymentRequest
from craftgate.request.dto import Card, PaymentItem

# Configure client (use sandbox for testing)
options = RequestOptions(
    api_key="<YOUR API KEY>",
    secret_key="<YOUR SECRET KEY>",
    base_url="https://sandbox-api.craftgate.io"
)
craftgate = Craftgate(options)
payment = craftgate.payment()

# Build basket
items = []
for name, price in [("item 1", "30"), ("item 2", "50"), ("item 3", "20")]:
    pi = PaymentItem()
    pi.name = name
    pi.external_id = str(uuid.uuid4())
    pi.price = Decimal(price)
    items.append(pi)

# Card info (sandbox test card)
card = Card()
card.card_holder_name = "Haluk Demir"
card.card_number = "5258640000000001"
card.expire_year = "2044"
card.expire_month = "07"
card.cvc = "000"

# Payment request
req = CreatePaymentRequest()
req.price = Decimal("100")
req.paid_price = Decimal("100")
req.wallet_price = Decimal("0")
req.installment = 1
req.currency = Currency.TRY
req.conversation_id = "456d1297-908e-4bd6-a13b-4be31a6e47d5"
req.payment_group = PaymentGroup.LISTING_OR_SUBSCRIPTION
req.payment_phase = PaymentPhase.AUTH
req.card = card
req.items = items

resp = payment.create_payment(req)
print(f"Create Payment Result: {resp}")

Idempotency

Mutating operations accept an optional idempotency key. Set it on the request object and the client sends it as the x-idempotency-key header, so a request can be safely retried (e.g. after a timeout) without the operation being performed twice — the server returns the result of the first request when it sees a repeated key.

Every request extends BaseRequest, which carries a HeaderOptions object, so the key is available on any request:

import uuid

from craftgate import HeaderOptions

req = CreatePaymentRequest()
req.price = Decimal("100")
req.paid_price = Decimal("100")
req.currency = Currency.TRY
req.payment_group = PaymentGroup.LISTING_OR_SUBSCRIPTION
req.header_options = HeaderOptions(idempotency_key=str(uuid.uuid4()))
# ... other fields

resp = payment.create_payment(req)

with_header_options() sets it inline and returns the request, which is handy for operations whose parameters live in the URL path:

payment.expire_checkout_payment(
    ExpireCheckoutPaymentRequest(token="456d1297-908e-4bd6-a13b-4be31a6e47d5")
    .with_header_options(HeaderOptions(idempotency_key=str(uuid.uuid4()))))

Use a fresh key per distinct operation, and reuse the same key when retrying that operation.

The API honours the key on POST, PATCH and DELETE only. It is ignored on PUT endpoints, so retrying one of those is not de-duplicated.

HeaderOptions is sent as headers only — it never appears in the request body, the query string, or the request signature.

Examples

A variety of end-to-end samples (3DS, Checkout, APM, refunds, stored cards, marketplace, pre/post-auth) live under the tests/ folder.

Run a single test:

python -m unittest tests.test_payment_sample.PaymentSample.test_create_payment
