Building messaging into your application does not have to be complicated. Galatext's developer APIs let you integrate SMS, WhatsApp, USSD, and Airtime disbursement with minimal code. Here is everything you need to start building.
Getting Started with Our APIs
All Galatext APIs use RESTful design with JSON request and response bodies. You will need an API key, which you can generate from your Galatext dashboard after creating a free account. Sign up for trial credits to test everything before committing.
SMS API: Send Your First Message
The SMS API endpoint accepts a recipient phone number, sender ID, and message body. A single POST request sends your message across all major East African networks — Safaricom, Airtel, Telkom, Vodacom, and MTN.
Key Features
- Delivery reports: Track every message status in real-time
- Scheduling: Queue messages for future delivery
- Bulk sending: Send to thousands of recipients in one API call
- Webhooks: Receive delivery callbacks on your server automatically
WhatsApp Business API: Rich Conversations
Our WhatsApp API supports message templates, interactive buttons, media messages, and catalogue integration. It is perfect for customer support, order updates, and marketing campaigns.
Airtime API: Instant Rewards
Disburse mobile airtime programmatically to any number in Kenya, Tanzania, or Uganda. Use it for loyalty rewards, survey incentives, or sales commissions. Airtime is credited instantly and works across all networks.
Webhooks for Real-Time Updates
Configure webhooks to receive instant notifications for inbound messages, delivery status changes, and payment confirmations. No polling needed — Galatext pushes events to your endpoint as they happen.
Best Practices for Developers
- Handle rate limits: Implement exponential backoff for retries
- Validate phone numbers: Use E.164 format (+254XXXXXXXXX for Kenya)
- Monitor webhook health: Configure retry logic for failed webhook deliveries
- Test in sandbox mode: Use our test environment before going live
