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 ParamsCopied!

Pass query params to this route.

  • productId (or productPriceId) ?productId=xxx

  • productPriceId (or productId) ?productPriceId=xxx

  • customerId (optional) ?productId=xxx&customerId=xxx

import { CustomerPortal } from "@polar-sh/nextjs";

export const GET = CustomerPortal({

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