  3. Validate tokens on every request.
  4. Rotate keys regularly to mitigate risks.

3. Best Practices

  • Always use HTTPS to protect transmitted data.
  • Store secrets in environment variables, not hardcoded.
  • Limit token scopes to minimize potential damage.
  • Refer to our Secure API Usage Guide for advanced configurations.
