Integration Guide

1

Review the API Documentation

Visit the official Postali documentation to understand available endpoints, request formats, and response structures. Familiarize yourself with the API's rate limits and usage policies before integration.

2

No Authentication Required

Good news — Postali does not require any authentication. You can start making API requests directly without registering for an API key or setting up OAuth credentials.

3

Use HTTPS for Secure Requests

Postali supports HTTPS, ensuring encrypted communication. Always use HTTPS endpoints in production to protect data in transit and comply with modern web security standards.

4

CORS Enabled — Direct Browser Access

Postali has CORS enabled, meaning you can make requests directly from the browser. This is ideal for frontend-only applications built with React, Vue, or vanilla JavaScript.

5

Implement and Test

Write your API integration code, start with a simple test request to verify connectivity. Implement proper error handling for network failures, rate limits, and invalid responses. Monitor your API usage to stay within any limits.

    }
    return response.json();
  })
