API Authentication and Security
This document outlines the authentication methods, security protocols, and best practices for accessing our platform via API.
[!IMPORTANT] All API requests must use HTTPS. Unencrypted HTTP requests will be rejected. Ensure your applications are configured to use secure connections.
1. API Key Authentication
The simplest method for service-to-service communication.
Request Format:
curl -H "Authorization: Bearer YOUR_API_KEY" \
https://api.platform.com/v1/resources
[!CAUTION] API Keys are sensitive credentials. Never expose them in client-side code or public repositories. Use environment variables or secure vaults for storage.
2. OAuth 2.0atform.com/v1/resources
Recommended for user-facing applications requiring delegated access.
Flow:
- Redirect user to authorization endpoint
- User grants permission
- Receive authorization code
- Exchange code for access token
- Use access token for API calls
Endpoint: https://auth.platform.com/oauth2/authorize
Security Best Practices
- ✅ Store keys securely in environment variables
- ✅ Rotate keys regularly (every 90 days)
- ✅ Use key scopes to limit permissions
- ❌ Never commit keys to version control
- ❌ Don't hardcode API keys in applications
[!TIP] Implement a key rotation schedule using automation. Our platform provides webhooks to notify you when keys are about to expire.

Rate Limiting
Each API key has the following rate limits:
| Tier | Requests/Hour | Burst |
|---|---|---|
| Free | 1,000 | 100 |
| Pro | 10,000 | 1,000 |
| Enterprise | Unlimited | Custom |
Response Codes
| Code | Meaning | Action |
|---|---|---|
| 200 | Success | Proceed normally |
| 401 | Unauthorized | Check API key validity |
| 403 | Forbidden | Verify scopes/permissions |
| 429 | Rate Limited | Implement backoff strategy |
Common Issues
"Rate Limit Exceeded"
- Implement exponential backoff
- Cache responses when possible
- Consider upgrading your tier
