Common questions
How long does M-Pesa integration take?+
For most businesses, 3-5 days from signup to production. CoreStack handles the Daraja API, STK Push flow, callbacks, and reconciliation. You just integrate one API endpoint.
Do I need my own M-Pesa Paybill or Till?+
Yes. You need your own Paybill or Till number from Safaricom. CoreStack connects to your existing shortcode — we don't intermediate funds.
What about failed payments and refunds?+
CoreStack tracks every payment state — success, timeout, cancelled, failed. You see exactly why a payment didn't complete, and refunds route through M-Pesa automatically.
Is there a test environment?+
Yes. Every integration gets a full sandbox with simulated STK Push, C2B, and webhook events. Test end-to-end before going live.
