# Introduction

> Integrate Xendit's Terminal C2C SDK for seamless in-person payment processing across multiple platforms

# Terminal C2C

<Info>
  **The Terminal C2C SDK is a convenience wrapper** around the [Terminal C2C API](/api-reference/c2c/introduction). For providers other than BRI and NTT, you can call the Terminal C2C API directly without the SDK. BRI and NTT terminals require either the [Gateway App](/sdk/gateway/app-configuration) or the C2C SDK as a pre-install.
</Info>

Xendit's Terminal C2C SDK enables direct local-network terminal control from your app. Use it when you need custom command flow ownership and device-side logic.

## What you can do with Terminal C2C

Terminal C2C provides everything you need to build in-person payment experiences:

* **Process payments** directly through terminal devices using a unified API
* **Manage terminal connections** and handle device configuration
* **Handle transactions** including payments, cancellations, receipts, and settlements
* **Support multiple platforms** including Android, iOS, and other KMP-compatible platforms
* **Connect to local gateway** for secure communication with payment terminals

<Info>
  Terminal C2C works alongside the Terminal Gateway service (the local application that communicates with physical payment devices) to provide a complete in-person payment solution. The C2C SDK sends commands to the Gateway service running on your local network.

## Choose your platform

Get started with Terminal C2C by selecting your development platform:

<Tip>
  If you still need to choose between H2H and C2C, start with [Quick Start](/guides/getting-started/quickstart) for the decision flow first.

## Prerequisites

Before you begin, ensure you have:

* A Xendit account with Terminal C2C access
* A valid client key for your environment
* Terminal Gateway service running locally (default port 8189)
* Physical payment terminal device information (Terminal ID and IP address) for supported providers (BRI, NTT, Cashup, SHC)
* Development environment set up for your chosen platform

## Next steps

1. **Set up your platform environment** and install the SDK
2. **Provision credentials** and terminal device information
3. **Integrate command flows** from the platform guide
4. **Validate with simulation and real devices** before rollout
