Trusted by developers in production
Teams across Africa rely on Uno SAP to power their WhatsApp integrations — reliably, at scale.
“We integrated Uno SAP into our loan disbursement system in half a day. The REST API is clean, the webhooks are reliable, and the session health monitoring has been a lifesaver.”

“We were using the official WhatsApp Business API — the cost and complexity were brutal. Uno SAP gave us the same capabilities at a fraction of the cost. Multi-session support is exactly what we needed.”

“The webhook signature verification works exactly as documented. We went live in production on day one. Our appointment reminders now have a 94% delivery rate.”
