Platform Overview

Galatext is a cloud-based communication platform that enables businesses to integrate SMS, WhatsApp, Airtime, and other messaging channels into their applications via simple REST APIs.

What is Galatext?

Galatext bridges the gap between businesses and their customers through reliable, scalable communication APIs. Whether you need to send transactional SMS notifications, engage users on WhatsApp, or reward customers with airtime, Galatext provides a unified API layer for all your messaging needs.

Key Capabilities

• SMS API — Send transactional, promotional, and bulk SMS to any network
• WhatsApp API — Send and receive WhatsApp messages, templates, and rich media
• Airtime API — Top up mobile airtime across African networks in real time
• Webhooks — Receive real-time delivery reports and incoming messages
• Bulk Messaging — Send personalized messages to thousands of recipients at once

Core Concepts

API Keys

API keys authenticate every request to the Galatext API. Each account can have multiple API keys for different environments or applications.

• Keys are passed via the x-api-key header
• Create and manage keys from the dashboard
• Rotate keys regularly for security

Credits

Galatext operates on a prepaid credit system. Each API operation deducts credits from your account balance:

Channel	Credit Cost
SMS (per message)	1 credit
WhatsApp (per message)	Varies by region
Airtime (per transaction)	Value + fee

You can top up credits via the dashboard or through our Airtime API for automated recharging.

Sender IDs

A sender ID is the name or number that appears as the sender of your message. Galatext provides:

• Default Sender ID — GALATEXT for quick testing
• Custom Sender IDs — Your brand name (e.g., YOURBRAND) after approval
• Numeric Sender IDs — Short codes or long numbers for two-way messaging

Message States

Messages flow through these states:

1. PENDING — Queued for delivery
2. SENT — Submitted to the carrier
3. DELIVERED — Successfully delivered to the recipient
4. FAILED — Delivery failed (check error codes)
