API Quickstart

Two authentication methods: JWT (for web/mobile apps) and API Keys (for server integrations).

Method 1: JWT Authentication

For web dashboards and mobile apps. Login once, use access tokens.

# 1. Login curl -X POST https://txtcow.goodamaze.com/api/auth/login \ -d '{"email":"user@example.com","password":"***"}' # Response: { "access_token": "...", "refresh_token": "..." } # 2. Send SMS curl -X POST https://txtcow.goodamaze.com/api/messages/send \ -H "Authorization: Bearer ACCESS_TOKEN" \ -d '{"recipient":"+64XXXXXXXXX","message":"Hello!"}'

Method 2: API Key (Legacy)

For server-to-server integrations. Create API key in dashboard.

# Send SMS with API Key curl -X POST https://txtcow.goodamaze.com/sms-gateway/api/send \ -H "Content-Type: application/json" \ -d '{ "api_key": "sk_live_XXXXXXXX", "phone": "+64XXXXXXXXX", "message": "Order #1234 confirmed!", "source": "woocommerce" }'

Frequently Asked Questions

What is BYON (Bring Your Own Number)?

Instead of using expensive cloud SMS services (Twilio, Vonage) or shared virtual numbers, TxtCow uses your own SIM card. This means lower costs, higher deliverability, and customers see your real business number.

What are the default quotas?

New users get: 10 messages/minute, 500 messages/day, 10,000 messages/month, and 1 service integration. Enterprise users can request higher limits via admin support.

Can I use multiple phones?

Yes! One account can connect multiple Android devices. Useful for load balancing, redundancy, or separating personal/business lines.

Is my data secure?

Yes. We use bcrypt password hashing, JWT secure tokens, SHA-256 API key encryption, HTTPS enforcement, and rate limiting. All production data is backed up daily.

Do I need to keep the app open?

The app polls for messages every 10 seconds in the background. For best results, disable battery optimization for TxtCow in Android settings.

Which countries are supported?

Any country with Android phone support. However, local carrier spam rules and sending limits may vary. Check with your carrier for SMS sending policies.
