How to authenticate with the Postixly API.
Authentication
All API requests must include your API key in the X-API-Key header.
X-API-Key: sp_your_api_key_here
You can generate an API key in your Account Settings > API Keys.
Security Note: Keep your API keys secure. Do not expose them in client-side code (browsers). If a key is compromised, revoke it immediately in your dashboard.
