Quickstart

Create an extension

Click New Extension in the dashboard. Give it a name and optionally upload an icon. Copy the Project ID — you’ll need it next.

Add tiers and prices

Inside your extension, click New Tier to create a tier (e.g. Pro, Business). Then add one or more prices to each tier — monthly, yearly, or one-time — with an amount.

Install the library

npm install @crxbase/payments

pnpm install @crxbase/payments

yarn install @crxbase/payments

Initialize the client

import { Client } from "@crxbase/payments";

const client = new Client("your_project_id");

Add a paywall

const user = await client.getUser();

if (user?.paid) {
  // Enable premium features
} else {
  // Prompt to subscribe
  client.openPricingPage();
}

That’s it. You can now add premium features in your extension. Next, see Developer Testing to test your extension before publishing.

Before you can accept payments from real users, you need to connect a Stripe account. See Stripe setup for details.
