Authentication

Secure your API usage with Bearer Token Authentication.

API Keys

To communicate with the SMS Gateway API, you must include an API Key in the Authorization header of your requests. You can manage your API keys in the Project Settings.

Security Warning

Your API Keys carry full privileges to send messages. Do not share them publicly in client-side code (browsers, mobile apps). Keep them secure on your backend server.

Header Format

Pass your key using the standard Bearer Token format:

Authorization: Bearer sk_live_your_api_key_here
