# Tenant API Code Examples in cURL, JS, PHP, Python

> Copy-ready Sinjapp Tenant API examples for sending messages, listing logs, and reading usage in cURL, JavaScript, PHP, and Python.

Use these examples as a starting point for your integration. Replace `{tenant}` with your tenant subdomain and keep API keys on the server side.
