API Integration Services — M-Pesa, eTIMS & ERPNext
Connect ERPNext to the services your business depends on

Frequently asked questions
How do you secure API integrations built on ERPNext?
All API integrations use TLS encryption, credential vaulting via Frappe's secure settings store, IP whitelisting where supported, and signed request verification. Sensitive tokens are never stored in plaintext. We follow OWASP API security best practices for every integration we deliver.
Which payment platforms and African APIs do you support?
We integrate with M-Pesa (STK push, B2B, B2C, C2B), Airtel Money, Stripe, Flutterwave, Pesapal, DPO Pay, and major bank APIs. For compliance, we cover KRA eTIMS, NHIF, NSSF, and KEBS. We also integrate Africa's Talking, Twilio, WhatsApp Business API, and regional logistics providers.
How long does an API integration project take?
A straightforward integration such as M-Pesa STK push typically takes 1–2 weeks including testing. More complex projects involving multiple endpoints, custom reconciliation logic, or compliance workflows take 3–6 weeks. We provide a detailed timeline estimate after an initial scoping call.
Do you maintain integrations after go-live?
Yes. We offer ongoing maintenance retainers that cover API version updates, monitoring, incident response, and enhancements. Payment provider APIs and government compliance APIs (like eTIMS) change frequently — our retainer ensures your integration stays current without disrupting operations.
How does error handling and retry logic work?
Every integration we build includes exponential back-off retry logic for transient failures, idempotency keys to prevent duplicate transactions, dead letter queues for permanently failed events, and alerting via email or WhatsApp when error thresholds are exceeded. You get full visibility through our logging dashboard before we hand over.
