# Google UCP Integration

## Overview

The **Universal Checkout Protocol (UCP)** enables autonomous shopping agents to complete purchases on behalf of consumers. By integrating Forter's Tokenization with UCP, merchants can securely accept payments from AI agents without handling raw card data.

## Setup

Add the Forter tokenization handler to your `/.well-known/ucp` endpoint:

### Sandbox

```json
{
  "payment": {
    "handlers": [
      {
        "id": "forter_tokenizer",
        "name": "com.forter.tokenizer",
        "version": "2026-01-14",
        "spec": "https://pci-tokenization-sandbox.checkouttools.com/v1/agentic/ucp/tokenizer_spec",
        "config_schema": "https://pci-tokenization-sandbox.checkouttools.com/v1/agentic/ucp/tokenize_schema.json",
        "instrument_schemas": [
          "https://ucp.dev/schemas/shopping/types/card_payment_instrument.json"
        ],
        "config": {
          "endpoint": "https://pci-tokenization-sandbox.checkouttools.com/v1/agentic/ucp/tokenize",
          "identity": {
            "access_token": "YOUR_FORTER_UCP_API_KEY",
            "site_id": "YOUR_FORTER_SITE_ID"
          }
        }
      }
    ]
  }
}
```

### Production

```json
{
  "payment": {
    "handlers": [
      {
        "id": "forter_tokenizer",
        "name": "com.forter.tokenizer",
        "version": "2026-01-14",
        "spec": "https://pci.checkouttools.com/v1/agentic/ucp/tokenizer_spec",
        "config_schema": "https://pci.checkouttools.com/v1/agentic/ucp/tokenize_schema.json",
        "instrument_schemas": [
          "https://ucp.dev/schemas/shopping/types/card_payment_instrument.json"
        ],
        "config": {
          "endpoint": "https://pci.checkouttools.com/v1/agentic/ucp/tokenize",
          "identity": {
            "access_token": "YOUR_FORTER_UCP_API_KEY",
            "site_id": "YOUR_FORTER_SITE_ID"
          }
        }
      }
    ]
  }
}
```

Contact your Forter account team to obtain a UCP API key.

## Processing Payments

When a shopping agent completes checkout, your backend receives a Forter token instead of raw card data. To process the payment, route it through Forter's [Detokenization Proxy](../Payment%20Optimization/Card%20Vaulting/Integration%20Guides/Detokenization%20Proxy.md), which resolves the token and forwards the request to your payment processor.

The proxy enforces token binding, ensuring tokens can only be used by the merchant they were issued to.
