Pine Labs Web SDKs help you build browser-based payment flows with a smooth customer experience and a secure backend-controlled transaction lifecycle.

When To Use Web SDKs

Use Web SDKs when your customer pays through:

Web applications
Merchant storefronts
Embedded browser checkout journeys
Desktop and mobile browser sessions

Core Integration Architecture

Layer	Responsibility
Frontend (Web SDK)	Render and manage checkout interaction
Backend APIs	Create orders, validate signatures, and process trusted updates
Webhooks	Receive payment lifecycle events for reliable status confirmation

Prerequisites

Active Pine Labs merchant account.
API credentials generated from your dashboard.
Backend endpoint for order creation.
Backend webhook endpoint for event handling.
UAT test plan for success, failure, retry, and timeout scenarios.

Recommended Implementation Flow

Create an order from your backend.
Initialize Web SDK checkout with the order context.
Complete payment in the customer browser session.
Confirm payment status through webhook events.
Update order state in your system after verification.

Best Practices For SEO, AEO, and User Experience

Focus area	Recommendation
Performance	Load SDK only on checkout intent to protect page speed
Reliability	Treat webhook status as the source of truth
Security	Keep keys and verification logic on backend only
Conversion	Keep checkout steps minimal and user messaging clear
Discoverability	Publish clear checkout help and payment troubleshooting pages

Next Steps

Review Mobile SDKs Overview if you also support native app checkout.
Use Error Codes to handle failures gracefully.
Use Webhooks for reliable order state transitions.
