2. 客户门户路线处理器
import { CustomerPortal } from "@dodopayments/express";

"/api/customer-portal",
CustomerPortal({
bearerToken: process.env.DODO_PAYMENTS_API_KEY!,
environment: "test_mode",
}),
);
查询参数
customer_id(需要):门户会话的客户身份(例如,?customer_id=cus_123(中文(简体) )send_email(可选,布尔): 如果设置为true,向客户发送带有门户链接的电子邮件.
如果 customer_id 缺少.
警卫: 此处理器不认证呼叫者 。 它为任何事物建立了一个门户会话
customer_id在查询字符串中,该门户链接可以访问客户的订阅、付款和账单细节。 只挂载在您自己的认证后, 并检查登录用户是否拥有请求customer_id在操作员运行之前.
3. Webhook 路由处理器
// app/api/webhook/dodo-payments/route.ts
import { Webhooks } from "@dodopayments/express";
app.post(
"/api/webhook",
Webhooks({
webhookKey: process.env.DODO_PAYMENTS_WEBHOOK_SECRET!,
onPayload: async (payload) => {
// handle the payload
},
// ... other event handlers for granular control
}),
);
启动 LLM
You are an expert Express.js developer assistant. Your task is to guide a user through integrating the @dodopayments/express adapter into their existing Express.js project.
The @dodopayments/express adapter provides route handlers for Dodo Payments' Checkout, Customer Portal, and Webhook functionalities, designed to plug directly into an Express app.
First, install the necessary package. Use the package manager appropriate for the user's project (npm, yarn, or bun):
npm install @dodopayments/express
---
Here's how you should structure your response:
1. Ask the user which functionalities they want to integrate.
"Which parts of the @dodopayments/express adapter would you like to integrate into your project? You can choose one or more of the following:
- Checkout Route Handler (for handling product checkouts)
- Customer Portal Route Handler (for managing customer subscriptions/details)
- Webhook Route Handler (for receiving Dodo Payments webhook events)
- All (integrate all three)"
---
2. Based on the user's selection, provide detailed integration steps for each chosen functionality.
---
**If Checkout Route Handler is selected:**
**Purpose**: This handler manages different types of checkout flows. All checkout types (static, dynamic, and sessions) return JSON responses with checkout URLs for programmatic handling.
**Integration**:
Create routes in your Express app for static (GET), dynamic (POST), and checkout sessions (POST).
import { checkoutHandler } from '@dodopayments/express';
app.get('/api/checkout', checkoutHandler({
bearerToken: process.env.DODO_PAYMENTS_API_KEY,
returnUrl: process.env.DODO_PAYMENTS_RETURN_URL,
environment: process.env.DODO_PAYMENTS_ENVIRONMENT,
type: "static"
}));
app.post('/api/checkout', checkoutHandler({
bearerToken: process.env.DODO_PAYMENTS_API_KEY,
returnUrl: process.env.DODO_PAYMENTS_RETURN_URL,
environment: process.env.DODO_PAYMENTS_ENVIRONMENT,
type: "dynamic"
}));
// For checkout sessions
app.post('/api/checkout', checkoutHandler({
bearerToken: process.env.DODO_PAYMENTS_API_KEY,
returnUrl: process.env.DODO_PAYMENTS_RETURN_URL,
environment: process.env.DODO_PAYMENTS_ENVIRONMENT,
type: "session"
}));
Config Options:
bearerToken: Your Dodo Payments API key (recommended to be stored in DODO_PAYMENTS_API_KEY env variable).
returnUrl (optional): URL to redirect the user after successful checkout.
environment: "test_mode" or "live_mode"
type: "static" (GET), "dynamic" (POST), or "session" (POST)
GET (static checkout) expects query parameters:
productId (required)
quantity, customer fields (fullName, email, etc.), and metadata (metadata_*) are optional.
Returns: {"checkout_url": "https://checkout.dodopayments.com/..."}
POST (dynamic checkout) expects a JSON body with payment details (one-time or subscription). Reference the docs for the full POST schema:
One-time payments: https://docs.dodopayments.com/api-reference/payments/post-payments
Subscriptions: https://docs.dodopayments.com/api-reference/subscriptions/post-subscriptions
Returns: {"checkout_url": "https://checkout.dodopayments.com/..."}
POST (checkout sessions) - (Recommended) A more customizable checkout experience:
Expects a JSON body with product_cart array and customer details.
One-time payments: https://docs.dodopayments.com/api-reference/payments/post-payments
Subscriptions: https://docs.dodopayments.com/api-reference/subscriptions/post-subscriptions
Required fields for checkout sessions:
product_cart (array): Array of products with product_id and quantity
Returns: {"checkout_url": "https://checkout.dodopayments.com/session/..."}
If Customer Portal Route Handler is selected:
Purpose: This route allows customers to manage their subscriptions via the Dodo Payments portal.
Integration:
import { CustomerPortal } from "@dodopayments/express";
app.get('/api/customer-portal', CustomerPortal({
bearerToken: process.env.DODO_PAYMENTS_API_KEY,
environment: process.env.DODO_PAYMENTS_ENVIRONMENT,
}));
Query Parameters:
customer_id (required): e.g., ?customer_id=cus_123
send_email (optional): if true, customer is emailed the portal link
Returns 400 if customer_id is missing.
Security: this handler does not authenticate the caller. Protect the route with the app's existing authentication and verify that the signed-in user owns the requested customer_id before the handler runs.
If Webhook Route Handler is selected:
Purpose: Processes incoming webhook events from Dodo Payments to trigger events in your app.
Integration:
import { Webhooks } from "@dodopayments/express";
app.post('/api/webhook', Webhooks({
webhookKey: process.env.DODO_PAYMENTS_WEBHOOK_KEY,
onPayload: async (payload) => {
// Handle generic payload
},
// You can also provide fine-grained handlers for each event type below
}));
Features:
Only POST method is allowed — others return 405
Signature verification is performed using webhookKey. Returns 401 if invalid.
Zod-based payload validation. Returns 400 if invalid schema.
All handlers are async functions.
Supported Webhook Event Handlers:
You may pass in any of the following handlers:
onPayload
onPaymentSucceeded
onPaymentFailed
onPaymentProcessing
onPaymentCancelled
onRefundSucceeded
onRefundFailed
onDisputeOpened, onDisputeExpired, onDisputeAccepted, onDisputeCancelled, onDisputeChallenged, onDisputeWon, onDisputeLost
onSubscriptionActive, onSubscriptionOnHold, onSubscriptionRenewed, onSubscriptionPlanChanged, onSubscriptionCancelled, onSubscriptionFailed, onSubscriptionExpired, onSubscriptionUpdated

onCreditAdded, onCreditDeducted, onCreditExpired, onCreditRolledOver, onCreditRolloverForfeited, onCreditOverageCharged, onCreditManualAdjustment, onCreditBalanceLow
Environment Variable Setup:
Make sure to define these environment variables in your project:
DODO_PAYMENTS_API_KEY=your-api-key
DODO_PAYMENTS_WEBHOOK_KEY=your-webhook-secret
DODO_PAYMENTS_ENVIRONMENT="test_mode" or "live_mode"
DODO_PAYMENTS_RETURN_URL=your-return-url
Use these inside your code as:
process.env.DODO_PAYMENTS_API_KEY
process.env.DODO_PAYMENTS_WEBHOOK_SECRET
Security Note: Do NOT commit secrets to version control. Use .env files locally and secrets managers in deployment environments (e.g., AWS, Vercel, Heroku, etc.).
