Wajub Python SDK

Official server-side SDK for the Wajub merchant API. Accept mobile-money and card payments across Africa with a Stripe-inspired, resource-oriented client.

Use Wajub.js for embedded checkout in the browser. Use this SDK on your backend with a secret (sk_) or restricted (rk_) API key — never expose secret keys in client-side code.

Features

• Resource-oriented API (wajub.payments, wajub.customers, …)
• Automatic Idempotency-Key on mutating requests (override per call)
• Typed errors per HTTP status (AuthenticationError, RateLimitError, …)
• Automatic retries on 429 and 5xx (max 2, exponential backoff)
• Page-based pagination with auto_paging_iter() and get_next_page()
• Webhook signature verification (HMAC-SHA256, timestamp tolerance)

Requirements

Installation

pip install wajub

Quick start

Amounts are passed in the smallest currency unit (e.g. cents for EUR/USD; whole francs for XAF).

Redirect checkout

import os
from wajub import Wajub

wajub = Wajub(api_key=os.environ["WAJUB_API_KEY"])

payment = wajub.payments.create({
    "amount": 15000,
    "currency": "XAF",
    "email": "buyer@example.com",
    "callback": "https://shop.example.com/order/complete",
})

print(payment.authorization_url)

Inline / overlay (embed token)

embed = wajub.payments.create({
    "amount": 15000,
    "currency": "XAF",
    "metadata": {"mode": "embed"},
})

# Pass to Wajub.js: embed.authorization_token

create() and retrieve() return a typed Payment object — prefer attribute access (payment.authorization_url). List pages from list() yield plain dicts.

Django / Flask

import os
from wajub import Wajub

wajub = Wajub(
    api_key=os.environ["WAJUB_API_KEY"],
    webhook_secret=os.environ.get("WAJUB_WEBHOOK_SECRET"),
)

Webhook view (Django)

Use the raw request body:

from django.http import HttpResponse, HttpResponseBadRequest
from django.views.decorators.csrf import csrf_exempt
from wajub import Wajub
from wajub import WebhookSignatureVerificationError

wajub = Wajub(api_key=os.environ["WAJUB_API_KEY"], webhook_secret=os.environ["WAJUB_WEBHOOK_SECRET"])

@csrf_exempt
def wajub_webhook(request):
    try:
        event = wajub.webhooks.construct_event(
            request.body,  # bytes — not request.POST or parsed JSON
            request.headers.get("X-Wajub-Signature", ""),
            request.headers.get("X-Wajub-Timestamp", ""),
        )
    except WebhookSignatureVerificationError:
        return HttpResponseBadRequest()

    if event.get("type") == "payment.succeeded":
        pass  # fulfill order

    return HttpResponse(status=200)

Note: global is a Python keyword. Use wajub.global_ to access global resources.

Configuration

Test mode is selected by your API key prefix (sk_test.…), not by the API URL. Production calls always go to https://api.wajub.com.

Resources (merchant API)

Sync (Connect)

from wajub import RequestOptions

wajub.payments.create(params, RequestOptions(sync="acct_sync_ref"))

Webhooks

from wajub import WebhookSignatureVerificationError

try:
    event = wajub.webhooks.construct_event(
        raw_body,  # bytes — must be raw body, not parsed JSON
        request.headers["X-Wajub-Signature"],
        request.headers["X-Wajub-Timestamp"],
    )
except WebhookSignatureVerificationError:
    return 400

if event.get("type") == "payment.succeeded":
    pass  # fulfill order

During local development, use the Wajub CLI to forward webhooks to your machine.

Pagination

page = wajub.payments.list({"per_page": 50})

for payment in page.auto_paging_iter():
    print(payment["id"], payment["status"])

# Manual page control
first = wajub.payments.list()
if first.has_more:
    second = first.get_next_page()

Idempotency

POST and PUT requests automatically receive an Idempotency-Key header. Pass your own:

from wajub import RequestOptions

wajub.payments.create(params, RequestOptions(idempotency_key=f"order-{order_id}"))

Error handling

from wajub import AuthenticationError, InvalidRequestError, RateLimitError

try:
    wajub.payments.create(params)
except InvalidRequestError as e:
    print(e.errors)  # field-level validation errors
except AuthenticationError:
    pass  # 401 — bad API key
except RateLimitError:
    pass  # 429 — back off and retry

Development

pip install -e ".[dev]"
pytest
