Security Best Practices

This section covers security guidelines and recommendations for integrating with B1Link.

API Key Security​

✅ Best Practices​

  • Store API keys in secure vaults (Azure Key Vault, AWS Secrets Manager, HashiCorp Vault)
  • Use environment variables in production (never hardcode)
  • Rotate API keys periodically
  • Use different API keys for development and production
  • Implement access controls to limit who can view API keys

❌ Never Do​

  • Never commit API keys to version control
  • Never log API keys in application logs
  • Never expose API keys in error messages or debugging output
  • Never share API keys via email or chat

Request Security​

✅ Best Practices​

  • Always use HTTPS for all API communications
  • Validate all input data before sending
  • Implement request retry logic with exponential backoff
  • Monitor for suspicious activity or failed signature verifications
  • Use constant-time comparison for signature verification (if implementing your own)

❌ Never Do​

  • Never send API keys in request bodies or query parameters
  • Never disable SSL/TLS certificate validation

Network Security​

✅ Best Practices​

  • Use firewall rules to restrict access to B1Link API endpoints
  • Implement network-level encryption
  • Monitor network traffic for anomalies
  • Use VPN or private networks when possible

Secure Storage Examples​

Environment Variables​

# Production
export B1LINK_API_KEY="your-api-key-here"

Azure Key Vault​

var secretClient = new SecretClient(
    new Uri("https://your-vault.vault.azure.net/"),
    new DefaultAzureCredential()
);
var apiKey = await secretClient.GetSecretAsync("B1LinkApiKey");

AWS Secrets Manager​

import boto3

secrets_client = boto3.client('secretsmanager')
response = secrets_client.get_secret_value(SecretId='B1LinkApiKey')
api_key = response['SecretString']
