# Overview

## 1. API Reference

Use this section if you want to connect your backend with honei services.\
Here you’ll find everything needed for **server-to-server** communication:

* **Getting Started**: How to authenticate and set up your environment.
* **Authorization**: Credentials, tokens, and environments (sandbox / production).
* **Endpoints**:
  * *New Sale* → create and initialize payment transactions.
  * *Other endpoints* depending on your workflow.

This is the recommended starting point for most integrations.

## 2. Android Integration

If you’re building a **third-party Android app** (POS, ordering system, etc.), honei Terminal can be invoked using **Android Intents**. This allows you to:

* **Payments**: Launch the payment flow from your app (`INIT_PAYMENT`) and receive the result back via `onActivityResult`.
* **Printing**: Send a structured JSON (`PRINT_TICKET`) to print receipts with text, images, and barcodes.

This approach requires no SDK — it’s a lightweight, intent-based integration.
