Step-by-step checklist for production-ready Universal Commerce Protocol integration across any e-commerce platform
UCP is designed to be modular and extensible to support rich commerce experiences, and offers different integration paths (Native and Embedded) to suit your brand and technical stack. A comprehensive checklist ensures your implementation is ready for agentic experiences and production-scale traffic.
Before beginning your UCP integration, assess your platform's readiness and choose the appropriate integration path. UCP offers different integration paths (Native and Embedded) to suit your brand and technical stack, so understanding your requirements is critical.
Platform Readiness Checklist:
• Catalog size and complexity assessment • Current search infrastructure evaluation • Checkout flow documentation • API rate limiting capabilities • Authentication system review • SSL/TLS certificate validation
The guide provides detailed instructions for developers integrating with the Universal Commerce Protocol, starting with understanding your platform's technical constraints. For stores using native WP queries, significant catalogs can become slow, making pre-integration assessment essential for performance planning.
UCP's flexibility means different integration paths are available depending on your needs. Native integration embeds UCP directly into your platform, while Embedded integration uses middleware or proxy layers. Consider your development resources, maintenance capabilities, and customization requirements when selecting your path.
The open-source interface standardizes integrations between consumer surfaces and ecosystem players, meaning your choice of integration path won't lock you into proprietary systems.
The discovery endpoint is where UCP's modular and extensible design enables AI agents to search your catalog. For stores using native WP queries, significant catalogs can become slow; integrating an indexed search solution or leveraging ElasticSearch can provide predictable latency and more powerful relevance tuning.
Discovery Implementation Steps:
1. Search Infrastructure Setup • Evaluate current search performance • Integrate an indexed search solution for large catalogs • Abstract search behind a service so the discovery endpoint can switch providers without changing the UCP contract
2. Response Format Validation • Implement proper product schema • Include all required product attributes • Test pagination for large result sets • Validate JSON response structure
3. Performance Optimization • Cache frequently accessed products • Implement query result caching • Set up CDN for product images • Monitor response times under load
A short checklist to validate discovery readiness should include search performance testing, schema validation, and latency benchmarking.
For stores using native WP queries, significant catalogs can become slow, making search optimization critical. Test your discovery endpoint with:
• 100+ concurrent search queries • Complex filter combinations • Pagination through large result sets • Fuzzy matching and typo tolerance
Measure response times and identify bottlenecks before production deployment. Integrating an indexed search solution or leveraging ElasticSearch can provide predictable latency that meets agentic commerce requirements.
// Example discovery endpoint response structure
{
"products": [
{
"id": "prod_123",
"name": "Product Name",
"price": {
"value": "29.99",
"currency": "USD"
},
"availability": "in_stock",
"images": ["https://cdn.example.com/image.jpg"]
}
],
"pagination": {
"total": 1500,
"page": 1,
"per_page": 20
}
}UCP's checkout integration provides flexibility in how transactions are completed. Options include generating a merchant-hosted checkout URL that the agent redirects to, or providing a delegated checkout API that completes the transaction via server-to-server calls.
Merchant-Hosted Checkout Checklist:
• Generate secure, time-limited checkout URLs • Pre-populate cart with agent-selected items • Maintain session state across redirects • Handle return URLs for completion/cancellation • Implement fraud detection on checkout pages
Delegated Checkout API Checklist:
• Implement server-to-server authentication • Validate payment method tokens • Process transactions without user redirect • Return detailed transaction status • Handle partial fulfillment scenarios
The practical checklist for Shopify UCP integration emphasizes production-ready deployment steps, including checkout flow testing and error handling.
Generating a merchant-hosted checkout URL that the agent redirects to gives you full control over the checkout experience while maintaining brand consistency. This approach works well when you need:
• Custom checkout flows with upsells • Existing payment gateway integrations • Complex shipping calculations • Loyalty program integration
Ensure checkout URLs are time-limited and single-use to prevent replay attacks. Include cart state in encrypted URL parameters or secure session tokens.
// Example merchant-hosted checkout URL generation
{
"checkout_url": "https://store.example.com/checkout/ucp_session_abc123",
"expires_at": "2024-01-15T10:30:00Z",
"cart_items": [
{
"product_id": "prod_123",
"quantity": 2,
"price": "29.99"
}
]
}Providing a delegated checkout API that completes the transaction via server-to-server calls enables seamless agentic transactions without user redirects. This approach requires:
• Robust authentication and authorization • Payment method tokenization • Idempotency key handling • Detailed error responses • Transaction status webhooks
The delegated API approach is ideal for supporting upcoming agentic capabilities, such as multi-item carts and account linking.
// Example delegated checkout API request
POST /ucp/checkout
{
"cart_items": [
{"product_id": "prod_123", "quantity": 2}
],
"payment_method": {
"type": "token",
"token": "pm_abc123"
},
"shipping_address": {
"line1": "123 Main St",
"city": "San Francisco",
"state": "CA",
"postal_code": "94102"
},
"idempotency_key": "unique_transaction_id"
}UCP's design supports account linking for loyalty programs and personalized experiences, requiring robust authentication implementation. Security considerations span API authentication, user authorization, and data protection.
Authentication Checklist:
• Implement OAuth 2.0 or API key authentication • Use HTTPS for all UCP endpoints • Validate JWT tokens on every request • Implement rate limiting per client • Log authentication attempts and failures • Set up API key rotation policies
Authorization Checklist:
• Define scope-based permissions • Implement customer account linking • Validate user consent for data access • Handle account delegation securely • Test permission boundaries
Data Protection:
• Encrypt sensitive data at rest • Use TLS 1.3 for data in transit • Implement PCI DSS compliance for payments • Sanitize all user inputs • Set up security monitoring and alerts
The detailed instructions for developers emphasize security best practices throughout the integration process.
Different integration paths suit different technical stacks, and platform-specific considerations ensure optimal implementation. The practical checklist for Shopify UCP integration and the ultimate WooCommerce UCP checklist provide platform-specific guidance.
Shopify-Specific Checklist:
• Leverage Shopify's GraphQL Admin API • Use Storefront API for product discovery • Implement checkout permalinks correctly • Handle Shopify's rate limits (2 requests/second) • Test with Shopify's webhook system • Validate against Shopify's app requirements
WooCommerce-Specific Checklist:
• For stores using native WP queries, integrate an indexed search solution • Use WooCommerce REST API v3 • Implement proper WordPress authentication • Optimize database queries for large catalogs • Test with popular WooCommerce extensions • Handle variable products correctly
BigCommerce/Magento Considerations:
• Leverage platform-native APIs • Implement proper caching strategies • Handle multi-store configurations • Test with platform-specific payment gateways
The guide provides detailed instructions that can be adapted to any platform's specific requirements.
For stores using native WP queries, significant catalogs can become slow, making search optimization critical for WooCommerce implementations. Integrating an indexed search solution or leveraging ElasticSearch can provide predictable latency and more powerful relevance tuning.
Search integration should be abstracted behind a service so the discovery endpoint can switch providers without changing the UCP contract. This abstraction enables you to upgrade search infrastructure without breaking UCP compatibility.
// WooCommerce search service abstraction
class UCPSearchService {
private $provider; // ElasticSearch, Algolia, etc.
public function search($query, $filters) {
// Abstract search logic
return $this->provider->search($query, $filters);
}
public function switchProvider($newProvider) {
// Change search backend without breaking UCP
$this->provider = $newProvider;
}
