Vipps OAuth plugin for Better Auth

A small plugin that adds Vipps MobilePay OAuth2/OpenID Connect to Better Auth.

Install

pnpm add @webstad/vipps-oauth-plugin
# peer dep
pnpm add better-auth

Quick start

import { betterAuth } from 'better-auth';
import { vippsOAuth } from '@webstad/vipps-oauth-plugin';

export const auth = betterAuth({
	plugins: [
		vippsOAuth({
			clientId: process.env.VIPPS_CLIENT_ID!,
			clientSecret: process.env.VIPPS_CLIENT_SECRET!,
			environment: process.env.NODE_ENV === 'production' ? 'prod' : 'test',
			// redirectUri: 'https://your.app/api/auth/callback', // optional
			// scopesPreset: 'basic', // or 'profile' | 'address'
		})
	]
});

Options (most common)

• environment: 'test' | 'prod'
• redirectUri: optional custom callback URL
• scopesPreset: 'basic' | 'profile' | 'address' (adds sensible scopes)
• scopes: custom scopes array (always includes openid)

You can also map the OIDC profile to your user schema:

vippsOAuth({
	/* ...required config... */
	mapProfileToUser: (profile) => ({ name: profile.name, email: profile.email })
});

Exports useful types like VippsOAuthConfig and VippsUserInfo.
