Authentication

The echowin API uses API keys to authenticate requests. You can view and manage your API keys in the API Keys page of your portal.

How it works

Authentication to the API is performed via API keys. Include your API key in the X-API-Key header for all API requests:

X-API-Key: your-api-key-here

Keep your API key secure!

Do not share your secret API keys in publicly accessible areas such as GitHub, client-side code, and so forth.

Making authenticated requests

Here's how to make an authenticated request using different programming languages:

cURL

curl https://echo.win/api/v1/contacts \
  -H "X-API-Key: your-api-key-here"

JavaScript

const response = await fetch('https://echo.win/api/v1/contacts', {
  headers: {
    'X-API-Key': 'your-api-key-here'
  }
});

Python

import requests

response = requests.get(
    'https://echo.win/api/v1/contacts',
    headers={'X-API-Key': 'your-api-key-here'}
)

API Key Management

Creating API Keys

API keys can be created from your portal settings. Each key is unique and tied to your team account.

Security Best Practices

  • Store API keys in environment variables
  • Never commit API keys to version control
  • Rotate keys regularly
  • Use different keys for different environments

Key Permissions

API keys have full access to your team's resources. They can perform any action that you can do in the portal.

Authentication Errors

The API will return specific error responses for authentication issues:

GET/api/v1/contacts

Example of authentication error responses

Responses

401Missing API Key
{
  "error": "Missing X-API-Key header"
}
401Invalid API Key
{
  "error": "Invalid API key"
}

Rate Limiting

API requests are subject to rate limiting to ensure fair usage:

  • Rate limit: 1000 requests per hour per API key
  • Burst limit: 100 requests per minute
  • Rate limit headers are included in all responses:
    • X-RateLimit-Limit: Maximum requests per hour
    • X-RateLimit-Remaining: Requests remaining in current window
    • X-RateLimit-Reset: Unix timestamp when the rate limit resets

Responses

429Rate limit exceeded
{
  "error": "Rate limit exceeded. Please try again later."
}
