Authentication

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.
