Configure Webhook Endpoint + +You can configure the webhook endpoint either through the Chargebee dashboard or programmatically via API. + +#### Option A: Via Chargebee Dashboard + +1. Go to **Settings β†’ Webhooks** in your Chargebee dashboard +2. Add webhook endpoint: `https://your-domain.com/api/auth/chargebee/webhook` +3. Enable **Basic Authentication**: + - Username: Your `CHARGEBEE_WEBHOOK_USERNAME` + - Password: Your `CHARGEBEE_WEBHOOK_PASSWORD` +4. Select events to listen to: + - `subscription_created` + - `subscription_activated` + - `subscription_changed` + - `subscription_renewed` + - `subscription_cancelled` + - `customer_deleted` + +#### Option B: Programmatically via API + +```typescript +import Chargebee from "chargebee"; + +const chargebeeClient = new Chargebee({ + site: process.env.CHARGEBEE_SITE!, + apiKey: process.env.CHARGEBEE_API_KEY!, +}); + +// Create webhook endpoint +const result = await chargebeeClient.webhookEndpoint.create({ + name: "Better Auth Webhook", + api_version: "v2", + url: "https://your-domain.com/api/auth/chargebee/webhook", + primary_url: true, + disabled: false, + basic_auth_username: process.env.CHARGEBEE_WEBHOOK_USERNAME, + basic_auth_password: process.env.CHARGEBEE_WEBHOOK_PASSWORD, + enabled_events: [ + "subscription_created", + "subscription_activated", + "subscription_changed", + "subscription_renewed", + "subscription_started", + "subscription_cancelled", + "subscription_cancellation_scheduled", + "customer_deleted", + ], +}); + +console.log("Webhook created:", result.webhook_endpoint.id); +``` + +### 2. Webhook Events Handled + +The plugin automatically handles these events: + +- **subscription_created** - Creates/updates subscription in database +- **subscription_activated** - Activates subscription +- **subscription_changed** - Updates subscription details +- **subscription_renewed** - Updates renewal information +- **subscription_cancelled** - Marks subscription as cancelled +- **customer_deleted** - Cleans up customer data + +### 3. Local Testing + +For local development, use ngrok or a similar tunneling service to expose your local server: + +```bash +# Install ngrok +npm install -g ngrok + +# Start your local development server +npm run dev # Running on http://localhost:3000 + +# In another terminal, create a tunnel +ngrok http 3000 + +# You'll get a public URL like: https://abc123.ngrok.io +``` + +Then create a webhook endpoint pointing to your ngrok URL: + +```typescript +// Create webhook for local testing +const result = await chargebeeClient.webhookEndpoint.create({ + name: "Local Development Webhook", + api_version: "v2", + url: "https://abc123.ngrok.io/api/auth/chargebee/webhook", + primary_url: false, // Don't make this primary + disabled: false, + basic_auth_username: "test", + basic_auth_password: "test123", + enabled_events: [ + "subscription_created", + "subscription_activated", + "subscription_changed", + "subscription_cancelled", + ], +}); +``` + +**Remember to:** +- Update your `.env.local` with the test credentials +- Delete the test webhook when done +- Use a non-primary webhook for testing + +### 4. Managing Webhooks Programmatically + +```typescript +// List all webhook endpoints +const webhooks = await chargebeeClient.webhookEndpoint.list({ limit: 100 }); +console.log("Existing webhooks:", webhooks.list); + +// Retrieve a specific webhook +const webhook = await chargebeeClient.webhookEndpoint.retrieve("webhook_id"); +console.log("Webhook details:", webhook.webhook_endpoint); + +// Update a webhook endpoint +await chargebeeClient.webhookEndpoint.update("webhook_id", { + disabled: true, // Disable temporarily + name: "Updated Webhook Name", +}); + +// Delete a webhook endpoint +await chargebeeClient.webhookEndpoint.delete("webhook_id"); +``` + +## API Endpoints + +### Available Endpoints + +| Endpoint | Method | Description | +|----------|--------|-------------| +| `/api/auth/chargebee/webhook` | POST | Webhook handler for Chargebee events | +| `/api/auth/subscription/upgrade` | POST | Create or upgrade subscription | +| `/api/auth/subscription/cancel` | POST | Cancel subscription | +| `/api/auth/subscription/cancel-callback` | POST | Handle cancellation callback | + +### Upgrade Subscription + +**Request:** +```typescript +POST /api/auth/subscription/upgrade + +{ + itemPriceId: string; + subscriptionId?: string; // For upgrades + successUrl: string; + cancelUrl: string; + trialEnd?: number; // Unix timestamp + seats?: number; // For seat-based plans + metadata?: Record; +} +``` + +**Response:** +```typescript +{ + url: string; // Chargebee hosted page URL + redirect: boolean; +} +``` + +### Cancel Subscription + +**Request:** +```typescript +POST /api/auth/subscription/cancel + +{ + subscriptionId: string; + returnUrl: string; +} +``` + +**Response:** +```typescript +{ + url: string; // Chargebee cancellation portal URL + redirect: boolean; +} +``` + +## Plugin Options + +### ChargebeeOptions + +```typescript +interface ChargebeeOptions { + // Required + chargebeeClient: Chargebee; + + // Optional + webhookUsername?: string; + webhookPassword?: string; + createCustomerOnSignUp?: boolean; + + // Callbacks + onCustomerCreate?: (params: { + chargebeeCustomer: Customer; + user: any; + }) => Promise | void; + + onEvent?: (event: any) => Promise | void; + + // Subscription + subscription?: { + enabled: boolean; + plans: ChargebeePlan[] | (() => Promise); + preventDuplicateTrails?: boolean; + requireEmailVerification?: boolean; + + // Lifecycle callbacks + onSubscriptionComplete?: (params: any) => Promise | void; + onSubscriptionCreated?: (params: any) => Promise | void; + onSubscriptionUpdate?: (params: any) => Promise | void; + onSubscriptionDeleted?: (params: any) => Promise | void; + + // Hosted page customization + getHostedPageParams?: ( + params: { + user: any; + session: any; + plan: ChargebeePlan; + subscription: Subscription; + }, + request: Request, + ctx: any, + ) => Promise>; + + // Authorization + authorizeReference?: ( + params: { + user: any; + session: any; + referenceId: string; + action: AuthorizeReferenceAction; + }, + ctx: any, + ) => Promise; + }; + + // Organization + organization?: { + enabled: boolean; + getCustomerCreateParams?: ( + organization: any, + ctx: any, + ) => Promise>; + onCustomerCreate?: ( + params: { + chargebeeCustomer: Customer; + organization: any; + }, + ctx: any, + ) => Promise | void; + }; +} +``` + +## Error Handling + +The plugin exports typed error codes: + +```typescript +import { CHARGEBEE_ERROR_CODES } from "@chargebee/better-auth"; + +// Available error codes +CHARGEBEE_ERROR_CODES.ALREADY_SUBSCRIBED +CHARGEBEE_ERROR_CODES.SUBSCRIPTION_NOT_FOUND +CHARGEBEE_ERROR_CODES.PLAN_NOT_FOUND +CHARGEBEE_ERROR_CODES.CUSTOMER_NOT_FOUND +CHARGEBEE_ERROR_CODES.UNAUTHORIZED_REFERENCE +CHARGEBEE_ERROR_CODES.EMAIL_VERIFICATION_REQUIRED +// ... and more +``` + +Handle errors in your application: + +```typescript +try { + await auth.api.upgradeSubscription({ ... }); +} catch (error) { + if (error.code === CHARGEBEE_ERROR_CODES.ALREADY_SUBSCRIBED) { + // Handle duplicate subscription + } +} +``` + +## TypeScript Support + +Full TypeScript support with type inference: + +```typescript +import type { + ChargebeeOptions, + ChargebeePlan, + Subscription, + SubscriptionStatus, +} from "@chargebee/better-auth"; + +// Types are automatically inferred from your configuration +const subscription: Subscription = { + id: "sub_123", + referenceId: "user_123", + status: "active", + // ...
