Checkout

Create a Checkout handler which takes care of redirections.

// checkout/route.ts
import { Checkout } from "@polar-sh/nextjs";

export const GET = Checkout({
	accessToken: process.env.POLAR_ACCESS_TOKEN,
	successUrl: process.env.SUCCESS_URL,
	server: "sandbox", // Use sandbox if you're testing Polar - omit the parameter or pass 'production' otherwise
});

Query Params

Pass query params to this route.

• productId (required) ?productId=xxx
• customerId (optional) ?productId=xxx&customerId=xxx
• customerEmail (optional) ?productId=xxx&[email protected]
• customerName (optional) ?productId=xxx&customerName=Jane

Customer Portal

Create a customer portal where your customer can view orders and subscriptions.

// portal/route.ts
import { CustomerPortal } from "@polar-sh/nextjs";

export const GET = CustomerPortal({
	accessToken: process.env.POLAR_ACCESS_TOKEN,
	getCustomerId: (req: NextRequest) => "", // Fuction to resolve a Polar Customer ID
	server: "sandbox", // Use sandbox if you're testing Polar - omit the parameter or pass 'production' otherwise
});

Webhooks

A simple utility which resolves incoming webhook payloads by signing the webhook secret properly.

// api/webhook/polar/route.ts
import { Webhooks } from "@polar-sh/nextjs";

export const POST = Webhooks({
	webhookSecret: process.env.POLAR_WEBHOOK_SECRET!,
	onPayload: async (payload) => {
		// Handle the payload
		// No need to return an acknowledge response
	},
});
