Plugins

Plugins extend PayKit by adding endpoints to its HTTP router. They're optional. Core PayKit works without any plugins.

Using a plugin

Install the plugin package, then pass it to createPayKit via the plugins array.

import { dash } from "@paykitjs/dash";

export const paykit = createPayKit({
  // ...
  plugins: [dash()],
});

Each plugin mounts its own endpoints under the PayKit base path automatically. No manual route wiring needed.

Dashboard plugin

@paykitjs/dash adds an embedded billing dashboard your users can access directly from your app. It shows subscriptions, invoices, and lets customers manage their payment methods.

pnpm add @paykitjs/dash

bun add @paykitjs/dash

npm install @paykitjs/dash

Pass an authorize function to control who can access it. Without authorize, the dashboard is open to any authenticated request.

import { dash } from "@paykitjs/dash";

export const paykit = createPayKit({
  // ...
  plugins: [
    dash({
      authorize: async (request) => {
        const session = await auth.api.getSession({
          headers: request.headers,
        });
        if (!session) throw new Error("Not authenticated");
      },
    }),
  ],
});

Throwing inside authorize blocks access. Returning without throwing grants it.

Plugin interface

A plugin is a plain object with an id and an optional endpoints map. PayKit mounts each endpoint under the configured base path.

type Plugin = {
  id: string;
  endpoints?: Record<string, EndpointHandler>;
};

The id must be unique across all plugins. PayKit uses it to namespace routes and avoid collisions.
