## Installation

<Steps>
  <Step title="Install the package">
    Führen Sie den folgenden Befehl im Stammverzeichnis Ihres Projekts aus:

    ```bash theme={null}
    npm install @dodopayments/convex
    ```
  </Step>

  <Step title="Add Component to Convex Config">
    Fügen Sie die Dodo Payments-Komponente zu Ihrer Convex-Konfiguration hinzu:

    ```typescript theme={null}
    // convex/convex.config.ts
    import { defineApp } from "convex/server";
    import dodopayments from "@dodopayments/convex/convex.config";

    const app = defineApp();
    app.use(dodopayments);
    export default app;
    ```

    Nachdem Sie `convex.config.ts` bearbeitet haben, führen Sie `npx convex dev` einmal aus, um die erforderlichen Typen zu generieren.
  </Step>

  <Step title="Set up environment variables">
    Richten Sie Umgebungsvariablen in Ihrem Convex-Dashboard ein (**Einstellungen** → **Umgebungsvariablen**). Sie erreichen das Dashboard, indem Sie Folgendes ausführen:

    ```bash theme={null}
    npx convex dashboard
    ```

    Fügen Sie die folgenden Umgebungsvariablen hinzu:

    * `DODO_PAYMENTS_API_KEY` - Ihr Dodo Payments-API-Schlüssel
    * `DODO_PAYMENTS_ENVIRONMENT` - auf `test_mode` oder `live_mode` setzen
    * `DODO_PAYMENTS_WEBHOOK_SECRET` - Ihr Webhook-Geheimnis (erforderlich für die Webhook-Verarbeitung)

    <Warning>
      Verwenden Sie immer Convex-Umgebungsvariablen für sensible Informationen. Speichern Sie Geheimnisse niemals in der Versionsverwaltung.
    </Warning>
  </Step>
</Steps>

## Beispiele zur Komponenteneinrichtung

<Steps>
  <Step title="Create Internal Query">
    Erstellen Sie zunächst eine interne Abfrage, um Kunden aus Ihrer Datenbank abzurufen. Diese wird in den Zahlungsfunktionen verwendet, um Kunden zu identifizieren.

    <Warning>
      Bevor Sie diese Abfrage verwenden, stellen Sie sicher, dass Sie das entsprechende Schema in Ihrer `convex/schema.ts`-Datei definieren oder die Abfrage an Ihr bestehendes Schema anpassen.
    </Warning>

    ```typescript theme={null}
    // convex/customers.ts
    import { internalQuery } from "./_generated/server";
    import { v } from "convex/values";

    // Internal query to fetch customer by auth ID
    export const getByAuthId = internalQuery({
      args: { authId: v.string() },
      handler: async (ctx, { authId }) => {
        return await ctx.db
          .query("customers")
          .withIndex("by_auth_id", (q) => q.eq("authId", authId))
          .first();
      },
    });

## Checkout-Funktion

<Info>
  Die Dodo Payments Convex-Komponente verwendet einen sitzungsbasierten Checkout und bietet ein sicheres, anpassbares Checkout-Erlebnis mit vorkonfigurierten Produktkörben und Kundendaten. Dies ist der empfohlene Ansatz für alle Zahlungsabläufe.
</Info>

### Verwendung

```typescript theme={null}
const result = await checkout(ctx, {
  payload: {
    product_cart: [{ product_id: "prod_123", quantity: 1 }],
    customer: { email: "user@example.com" },
    return_url: "https://example.com/success"
  }
});
```

Siehe [Checkout-Sitzungen](/developer-resources/checkout-session) für weitere Details und eine vollständige Liste der unterstützten Felder.

### Antwortformat

Die Checkout-Funktion gibt eine JSON-Antwort mit der Checkout-URL zurück:

```json theme={null}
{
  "checkout_url": "https://checkout.dodopayments.com/session/..."
}
```

## Kundenportal-Funktion

Die Kundenportal-Funktion ermöglicht es Ihnen, das Dodo Payments-Kundenportal nahtlos in Ihre Convex-Anwendung zu integrieren.

### Verwendung

```typescript theme={null}
const result = await customerPortal(ctx, {
  send_email: false
});
```

### Parameter

<ParamField query="send_email" type="boolean">
  Wenn auf <code>true</code> gesetzt, wird eine E-Mail mit dem Portal-Link an den Kunden gesendet.
</ParamField>

<Info>
  Der Kunde wird automatisch über die `identify`-Funktion identifiziert, die in Ihrer DodoPayments-Konfiguration eingerichtet ist. Diese Funktion sollte die `dodoCustomerId` des Kunden zurückgeben.
</Info>

## Webhook-Handler

* **Methode:** Nur POST-Anfragen werden unterstützt. Andere Methoden geben 405 zurück.
* **Signaturverifizierung:** Überprüft die Webhook-Signatur mit <code>DODO\_PAYMENTS\_WEBHOOK\_SECRET</code>. Gibt 401 zurück, wenn die Überprüfung fehlschlägt.
* **Payload-Validierung:** Mit Zod validiert. Gibt 400 für ungültige Payloads zurück.
* **Fehlerbehandlung:**
  * 401: Ungültige Signatur
  * 400: Ungültige Payload
  * 500: Interner Fehler während der Überprüfung
* **Ereignisweiterleitung:** Ruft den entsprechenden Ereignishandler basierend auf dem Payload-Typ auf.

## Eingabeaufforderung für LLM

```
You are an expert Convex developer assistant. Your task is to guide a user through integrating the @dodopayments/convex component into their existing Convex application.

The @dodopayments/convex adapter provides a Convex component for Dodo Payments' Checkout, Customer Portal, and Webhook functionalities, built using the official Convex component architecture pattern.

First, install the necessary package:

npm install @dodopayments/convex

Here's how you should structure your response:

1. Ask the user which functionalities they want to integrate.

"Which parts of the @dodopayments/convex component would you like to integrate into your project? You can choose one or more of the following:

- Checkout Function (for handling product checkouts)
- Customer Portal Function (for managing customer subscriptions/details)
- Webhook 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 Function is selected:

Purpose: This function handles session-based checkout flows and returns checkout URLs for programmatic handling.

Integration Steps:

Step 1: Add the component to your Convex configuration.

// convex/convex.config.ts
import { defineApp } from "convex/server";
import dodopayments from "@dodopayments/convex/convex.config";

const app = defineApp();
app.use(dodopayments);
export default app;

Step 2: Guide the user to set up environment variables in the Convex dashboard. Instruct them to open the dashboard by running:

npx convex dashboard

Then add the required environment variables (e.g., DODO_PAYMENTS_API_KEY, DODO_PAYMENTS_ENVIRONMENT, DODO_PAYMENTS_WEBHOOK_SECRET) in **Settings → Environment Variables**. Do not use .env files for backend functions.

Step 3: Create an internal query to fetch customers from your database.
Note: Ensure the user has appropriate schema defined in their convex/schema.ts file or modify the query to match their existing schema.

// convex/customers.ts
import { internalQuery } from "./_generated/server";
import { v } from "convex/values";

// Internal query to fetch customer by auth ID
export const getByAuthId = internalQuery({
  args: { authId: v.string() },
  handler: async (ctx, { authId }) => {
    return await ctx.db
      .query("customers")
      .withIndex("by_auth_id", (q) => q.eq("authId", authId))
      .first();
  },
});

Step 4: Create your payment functions file.

// convex/dodo.ts
import { DodoPayments, DodoPaymentsClientConfig } from "@dodopayments/convex";
import { components } from "./_generated/api";
import { internal } from "./_generated/api";

export const dodo = new DodoPayments(components.dodopayments, {
  // This function maps your Convex user to a Dodo Payments customer
  // Customize it based on your authentication provider and user database
  identify: async (ctx) => {
    const identity = await ctx.auth.getUserIdentity();
    if (!identity) {
      return null; // User is not logged in
    }
    
    // Use ctx.runQuery() to lookup customer from your database
    const customer = await ctx.runQuery(internal.customers.getByAuthId, {
      authId: identity.subject,
    });
    
    if (!customer) {
      return null; // Customer not found in database
    }
    
    return {
      dodoCustomerId: customer.dodoCustomerId, // Replace customer.dodoCustomerId with your field storing Dodo Payments customer ID
    };
  },
  apiKey: process.env.DODO_PAYMENTS_API_KEY!,
  environment: process.env.DODO_PAYMENTS_ENVIRONMENT as "test_mode" | "live_mode",
} as DodoPaymentsClientConfig);

// Export the API methods for use in your app
export const { checkout, customerPortal } = dodo.api();

Step 5: Create actions that use the checkout function.

// convex/payments.ts
import { action } from "./_generated/server";
import { v } from "convex/values";
import { checkout } from "./dodo";

// Checkout session with full feature support
export const createCheckout = action({
  args: { 
    product_cart: v.array(v.object({
      product_id: v.string(),
      quantity: v.number(),
    })),
    returnUrl: v.optional(v.string()),
  },
  handler: async (ctx, args) => {
    return await checkout(ctx, {
      payload: {
        product_cart: args.product_cart,
        return_url: args.returnUrl,
        billing_currency: "USD",
        feature_flags: {
          allow_discount_code: true,
        },
      },
    });
  },
});

Step 6: Use in your frontend.

// Your frontend component
import { useAction } from "convex/react";
import { api } from "../convex/_generated/api";

export function CheckoutButton() {
  const createCheckout = useAction(api.payments.createCheckout);

  const handleCheckout = async () => {
    const { checkout_url } = await createCheckout({
      product_cart: [{ product_id: "prod_123", quantity: 1 }],
    });
    window.location.href = checkout_url;
  };

  return <button onClick={handleCheckout}>Buy Now</button>;
}

Configuration Details:

- `checkout()`: Checkout session with full feature support using session checkout.
- Returns: `{"checkout_url": "https://checkout.dodopayments.com/..."}`

For complete API documentation, refer to:
- Checkout Sessions: https://docs.dodopayments.com/developer-resources/checkout-session
- One-time Payments: https://docs.dodopayments.com/api-reference/payments/post-payments
- Subscriptions: https://docs.dodopayments.com/api-reference/subscriptions/post-subscriptions

If Customer Portal Function is selected:

Purpose: This function allows customers to manage their subscriptions and payment methods. The customer is automatically identified via the `identify` function.

Integration Steps:

Follow Steps 1-4 from the Checkout Function section, then:

Step 5: Create a customer portal action.

// convex/payments.ts (add to existing file)
import { action } from "./_generated/server";
import { v } from "convex/values";
import { customerPortal } from "./dodo";

export const getCustomerPortal = action({
  args: {
    send_email: v.optional(v.boolean()),
  },
  handler: async (ctx, args) => {
    try {
      const portal = await customerPortal(ctx, args);
      if (!portal?.portal_url) {
        throw new Error("Customer portal did not return a portal_url");
      }
      return portal;
    } catch (error) {
      console.error("Failed to generate customer portal link", error);
      throw new Error("Unable to generate customer portal link. Please retry.");
    }
  },
});

Step 6: Use in your frontend.

// Your frontend component
import { useAction } from "convex/react";
import { api } from "../convex/_generated/api";

export function CustomerPortalButton() {
  const getPortal = useAction(api.payments.getCustomerPortal);

  const handlePortal = async () => {
    const { portal_url } = await getPortal({ send_email: false });
    window.location.href = portal_url;
  };

  return <button onClick={handlePortal}>Manage Subscription</button>;
}

Configuration Details:
- Requires authenticated user (via `identify` function).
- Customer identification is handled automatically by the `identify` function.
- `send_email`: Optional boolean to send portal link via email.

If Webhook Handler is selected:

Purpose: This handler processes incoming webhook events from Dodo Payments, allowing your application to react to events like successful payments or subscription changes.

Integration Steps:

Step 1: Add the webhook secret to your environment variables in the Convex dashboard. You can open the dashboard by running:

Guide the user to open the Convex dashboard by running:

npx convex dashboard

In the dashboard, go to **Settings → Environment Variables** and add:

- `DODO_PAYMENTS_WEBHOOK_SECRET=whsec_...`

Do not use .env files for backend functions; always set secrets in the Convex dashboard.

Step 2: Create a file `convex/http.ts`:

// convex/http.ts
import { createDodoWebhookHandler } from "@dodopayments/convex";
import { httpRouter } from "convex/server";
import { internal } from "./_generated/api";

const http = httpRouter();

http.route({
  path: "/dodopayments-webhook",
  method: "POST",
  handler: createDodoWebhookHandler({
    // Handle successful payments
    onPaymentSucceeded: async (ctx, payload) => {
      console.log("🎉 Payment Succeeded!");

      // Use Convex context to persist payment data
      await ctx.runMutation(internal.webhooks.createPayment, {
        paymentId: payload.data.payment_id,
        businessId: payload.business_id,
        customerEmail: payload.data.customer.email,
        amount: payload.data.total_amount,
        currency: payload.data.currency,
        status: payload.data.status,
        webhookPayload: JSON.stringify(payload),
      });
    },

    // Handle subscription activation
    onSubscriptionActive: async (ctx, payload) => {
      console.log("🎉 Subscription Activated!");
      // Use Convex context to persist subscription data
      await ctx.runMutation(internal.webhooks.createSubscription, {
        subscriptionId: payload.data.subscription_id,
        businessId: payload.business_id,
        customerEmail: payload.data.customer.email,
        status: payload.data.status,
        webhookPayload: JSON.stringify(payload),
      });
    },
    // Add other event handlers as needed
  }),
});

export default http;

Note: Make sure to define the corresponding database mutations in your Convex backend for each webhook event you want to handle. For example, create a `createPayment` mutation to record successful payments or a `createSubscription` mutation to manage subscription state.

Now, you can set the webhook endpoint URL in your Dodo Payments dashboard to `https://<your-convex-deployment-url>/dodopayments-webhook`.

Environment Variable Setup:

Set up the following environment variables in your Convex dashboard if you haven't already (Settings → Environment Variables):

- `DODO_PAYMENTS_API_KEY` - Your Dodo Payments API key
- `DODO_PAYMENTS_ENVIRONMENT` - Set to `test_mode` or `live_mode`
- `DODO_PAYMENTS_WEBHOOK_SECRET` - Your webhook secret (required for webhook handling)

Usage in your component configuration:

apiKey: process.env.DODO_PAYMENTS_API_KEY
environment: process.env.DODO_PAYMENTS_ENVIRONMENT as "test_mode" | "live_mode"

Important: Never commit sensitive environment variables directly into your code. Always use Convex environment variables for all sensitive information.

If the user needs assistance setting up environment variables or deployment, ask them about their specific setup and provide guidance accordingly.

Run `npx convex dev` after setting up the component to generate the necessary types.
