autumn-create-customer（秋季创建客户）

Autumn Customer Setup

Always consult docs.useautumn.com for code examples and latest API.

Quick Reference

Environment Variables

• AUTUMN_SECRET_KEY - Required. Get one at app.useautumn.com

Installation

npm install autumn-js    # Node.js
pip install autumn-py    # Python

Integration Paths

Path A: React + Node.js

Handler Setup

import { autumnHandler } from "autumn-js/next";

export const { GET, POST } = autumnHandler({
  identify: async (request) => {
    const session = await getSession(request);
    return {
      customerId: session.user.id,  // or session.org.id for B2B
      customerData: { name: session.user.name, email: session.user.email },
    };
  },
});

Client Setup

import { AutumnProvider } from "autumn-js/react";

<AutumnProvider>{children}</AutumnProvider>

// Different backend URL:
<AutumnProvider backendUrl={process.env.NEXT_PUBLIC_API_URL} />

Verify

import { useCustomer } from "autumn-js/react";

const { customer } = useCustomer();
console.log("Autumn customer:", customer);

Path B: Backend Only

Initialize

import { Autumn } from "autumn-js";

const autumn = new Autumn({ secretKey: process.env.AUTUMN_SECRET_KEY });

from autumn import Autumn

autumn = Autumn('am_sk_test_xxx')

Create Customer

const { data } = await autumn.customers.create({
  id: "user_id_from_auth",
  name: "Test User",
  email: "test@example.com",
});

Common Gotchas

1. B2C vs B2B - Decide if customerId is user ID or org ID before integrating
2. Idempotent - customers.create returns existing customer if ID exists
3. Backend URL - Pass backendUrl to provider if API is on different domain
4. Secret key - Keep AUTUMN_SECRET_KEY server-side only
