Build for Africa Hackathon 2026
Hack. Build. Ship. One integration, 54 countries.
Useful products, built on African infrastructure
eSMS Africa gives you REST APIs, SMPP, a full sandbox and official SDKs. Here are a few directions - the best ideas are the ones we haven't thought of yet.
Fintech notifications
Transaction alerts, balance updates and payment confirmations that reach customers instantly across borders.
School communication
Parent-teacher messaging, attendance alerts and fee reminders for schools and universities.
Healthcare reminders
Appointment reminders, medication nudges and clinic follow-ups that reduce no-shows.
Emergency & community alerts
Fast, reliable notification tools for communities, NGOs and public services.
E-commerce updates
Order confirmations, delivery tracking and abandoned-cart nudges over SMS.
Developer tools
CLIs, libraries and integrations that make messaging easier for other builders.
AI agents over SMS
Assistants that talk to users through plain SMS - no smartphone or data required.
Multi-country apps
One integration that communicates with users in several African markets at once.
Build without spending a cent
Every account comes with a sandbox. Use an esms_test_ key to test requests, responses and delivery webhooks end to end - without sending a single real SMS or using any balance.
- Real API responses and simulated delivery reports.
- Test OTP flows with a fixed code that always verifies.
- Magic numbers to simulate failures and edge cases.
- Flip to a live key and go to production - same code.
curl -X POST https://sms.esmsafrica.io/api/messages/send \
-H "Authorization: Bearer esms_test_..." \
-H "Content-Type: application/json" \
-d '{"to":"+254712345678","text":"Hello Africa"}'
