Danipa Python SDK

Official Python SDK for the Danipa fintech API — collections, disbursements, wallets, payment links, invoices, and webhook signature verification.

Install

pip install danipa

Requires Python 3.10+.

Quick start

import os
from danipa import Danipa, RequestOptions
from danipa.models import CreateCollectionRequest, Payer

# Sandbox vs production is inferred from the API key prefix:
#   dk_test_… → https://api.sandbox.danipa.com
#   dk_live_… → https://api.danipa.com
with Danipa(api_key=os.environ["DANIPA_API_KEY"]) as danipa:
    collection = danipa.collections.create(
        CreateCollectionRequest(
            amount="125.00",
            currency="GHS",
            payer=Payer(phone="+233244112233", name="Ama K."),
        ),
        options=RequestOptions(idempotency_key="order-1234"),
    )

Resources

Resource	Methods
danipa.collections	create, get
danipa.disbursements	create, get
danipa.wallets	get_balance
danipa.payment_links	create
danipa.invoices	create

Errors

from danipa import DanipaApiError, DanipaNetworkError

try:
    danipa.collections.create(...)
except DanipaApiError as exc:
    # Backend returned a non-2xx response
    print(exc.status, exc.code, exc.correlation_id, exc.raw)
except DanipaNetworkError as exc:
    # Transport failure (DNS, TLS, timeout). exc.cause is the underlying httpx error.
    ...

DanipaApiError and DanipaNetworkError both inherit from DanipaError — catch the base class once and narrow if you need the details.

Idempotency, retries, timeouts

• Pass options=RequestOptions(idempotency_key=...) on every mutating call. Backend dedupes on (merchantId, key) so retries (server- or client-side) won't double-charge.
• Default retry policy: 3 attempts on 5xx and transport failures, with 200 ms × 2^(attempt - 1) exponential backoff capped at 2 s, plus 0–50 ms jitter. 4xx responses never retry — they indicate a client-side fix is needed.
• Override per client: Danipa(api_key=..., timeout=30.0, max_retries=3). Override per call: RequestOptions(timeout=10.0).

Webhook signature verification

from danipa import verify_webhook

if not verify_webhook(payload, signature, timestamp, secret):
    raise PermissionError("invalid signature")

Cross-SDK parity: every Danipa SDK (Node, Java, Python, PHP) produces identical signatures for the same (payload, secret, timestamp) triple. Drift is treated as a release-blocker.

Framework examples

FastAPI

from fastapi import FastAPI, Header, HTTPException, Request
from danipa import verify_webhook

app = FastAPI()

@app.post("/webhooks/danipa")
async def webhook(
    request: Request,
    x_danipa_signature: str = Header(...),
    x_danipa_timestamp: str = Header(...),
):
    body = (await request.body()).decode("utf-8")
    if not verify_webhook(body, x_danipa_signature, x_danipa_timestamp, SECRET):
        raise HTTPException(status_code=401, detail="invalid signature")
    ...

Flask

from flask import Flask, request, abort
from danipa import verify_webhook

app = Flask(__name__)

@app.post("/webhooks/danipa")
def webhook():
    if not verify_webhook(
        request.get_data(as_text=True),
        request.headers.get("X-Danipa-Signature", ""),
        request.headers.get("X-Danipa-Timestamp", ""),
        SECRET,
    ):
        abort(401)
    ...
