Getting Started with Our API

Learn how to integrate our SMS services into your applications with our RESTful API.

Start Integration

Why Our API?

Our API allows you to send and receive text messages, automate workflows, and integrate with your business systems using simple REST endpoints. With our API, you can:

  • Send bulk SMS messages
  • Implement two-factor authentication
  • Receive and store delivery reports
  • Integrate with your CRM and marketing systems

Step 1: Get Your API Credentials

Before you start using our API, you'll need to obtain an API key. This key will be used to authenticate each API call.

Create an API Key

  1. Log in to your account
  2. Go to Developer Settings
  3. Create a new API key with appropriate permissions

Environment Variables

API_KEY='your-api-key'

Store your API key securely in environment variables

Tip: Always rotate your API keys every 90 days for security

Step 2: Your First API Call

To make our first API call, we'll send a simple message using cURL:

Example: Send SMS

curl -X POST "https://api.egkkikikifistis.gr/v1/sms" \
     -H "Authorization: Bearer YOUR_API_KEY" \
     -H "Content-Type: application/json" \
     -d '{"to":"1234567890","body":"Hello world!"}'

You can expect the following response:

{
  "id": "123456",
  "to": "1234567890",
  "body": "Hello world!",
  "sent": "2025-10-05T10:05:00Z"
}

Tip: Make sure to replace YOUR_API_KEY with your actual API key before testing

Best Practices

Error Handling

Use try/catch blocks when making API calls. Our API returns JSON error objects when errors occur.

Rate Limiting

We recommend no more than 100 messages per second to ensure system stability and reliability.

Message Testing

Use our sandbox environment to test message templates before sending them to real users.
