Installation

Choose your preferred package manager to install the module: pnpm add @polar-sh/nuxt

​
Register the module

Add the module to your nuxt.config.ts: 
export default defineNuxtConfig({
  modules: ["@polar-sh/nuxt"],
});

​
Checkout

Create a Checkout handler which takes care of redirections. 
// server/routes/api/checkout.post.ts
export default defineEventHandler((event) => {
  const {
    private: { polarAccessToken, polarCheckoutSuccessUrl, polarServer },
  } = useRuntimeConfig();

  const checkoutHandler = Checkout({
    accessToken: polarAccessToken,
    successUrl: polarCheckoutSuccessUrl,
    server: polarServer as "sandbox" | "production",
  });

  return checkoutHandler(event);
});

​
Query Params

Pass query params to this route.
  • products ?products=123
  • customerId (optional) ?products=123&customerId=xxx
  • customerExternalId (optional) ?products=123&customerExternalId=xxx
  • customerEmail (optional) ?products=123&[email protected]
  • customerName (optional) ?products=123&customerName=Jane
  • metadata (optional) URL-Encoded JSON string

​
Customer Portal

Create a customer portal where your customer can view orders and subscriptions. 
// server/routes/api/portal.get.ts
export default defineEventHandler((event) => {
  const {
    private: { polarAccessToken, polarCheckoutSuccessUrl, polarServer },
  } = useRuntimeConfig();

  const customerPortalHandler = CustomerPortal({
    accessToken: polarAccessToken,
    server: polarServer as "sandbox" | "production",
    getCustomerId: (event) => {
      // Use your own logic to get the customer ID - from a database, session, etc.
      return Promise.resolve("9d89909b-216d-475e-8005-053dba7cff07");
    },
  });

  return customerPortalHandler(event);
});

​
Webhooks

A simple utility which resolves incoming webhook payloads by signing the webhook secret properly. 
// server/routes/webhook/polar.post.ts
export default defineEventHandler((event) => {
  const {
    private: { polarWebhookSecret },
  } = useRuntimeConfig();

  const webhooksHandler = Webhooks({
    webhookSecret: polarWebhookSecret,
    onPayload: async (payload) => {
      // Handle the payload
      // No need to return an acknowledge response
    },
  });

  return webhooksHandler(event);
});

​
