Better Auth Integration

Better Auth Integration

Use @dodopayments/better-auth to synchronize Better Auth users with Dodo Payments and expose authenticated checkout, customer portal, subscription, payment, usage, and webhook endpoints.

When to use this skill

• Create a Dodo customer automatically when a Better Auth user signs up.
• Start checkout for a signed-in user without exposing a Dodo API key.
• Let users open their customer portal or list their subscriptions and payments.
• Submit metered usage for the signed-in customer.
• Receive signature-verified Dodo webhooks through Better Auth.

Install

npm install @dodopayments/better-auth dodopayments better-auth

The package exports the lowercase server functions dodopayments, checkout, portal, usage, and webhooks. Its client entry point exports dodopaymentsClient.

Server setup

Every endpoint is registered by a feature in use. Include every feature that the application calls; omitting one makes its route return 404.

import { betterAuth } from "better-auth";
import DodoPayments from "dodopayments";
import { checkout, dodopayments, portal, usage, webhooks } from "@dodopayments/better-auth";

const dodoPayments = new DodoPayments({
  bearerToken: process.env.DODO_PAYMENTS_API_KEY,
  environment: "test_mode",
});

export const auth = betterAuth({
  database: {
    // your database config
  },
  plugins: [
    dodopayments({
