💳Integrated Payments with Stripe and Paddle: Inside EasyLaunchpad’s Payment Module

When building a SaaS app, one of the first questions you’ll face is:

How will we charge users?

From recurring subscriptions to one-time payments and license plans, payment infrastructure is mission-critical. But implementing a secure, production-grade system can be time-consuming, tricky, and expensive.

That’s why EasyLaunchpad includes a fully integrated payment module with support for Stripe and Paddle — out of the box.

In this article, we’ll walk you through how EasyLaunchpad handles payments, how it simplifies integration with major processors, and how it helps you monetize your product from day one.

💡 The Problem: Payment Integration Is Hard

On paper, adding Stripe or Paddle looks easy. In reality, it involves:

• API authentication
• Checkout flows
• Webhook validation
• Error handling
• Subscription plan logic
• Admin-side controls
• Syncing with your front-end or product logic

That’s a lot to build before you ever collect your first dollar.

EasyLaunchpad solves this by offering a turnkey payment solution that integrates Stripe and Paddle seamlessly into backend logic and your admin panel.

⚙️ What’s Included in the Payment Module?

The EasyLaunchpad payment module covers everything a SaaS app needs to start selling:

Feature and Description:

✅ Stripe & Paddle APIs- Integrated SDKs with secure API keys managed via config

✅ Plan Management- Define your product plans via admin panel

✅ License/Package Linking- Link Stripe/Paddle plans to system logic (e.g., access control)

✅ Webhook Support- Process events like successful payments, cancellations, renewals

✅ Email Triggers- Send receipts and billing notifications automatically

✅ Logging & Retry Logic- Serilog + Hangfire for reliability and transparency

💳 Stripe Integration in .NET Core (Prebuilt)

Stripe is the most popular payment solution for modern SaaS businesses. EasyLaunchpad comes with:

Stripe.NET SDK is configured and ready to use

Test & production API key support via appsettings.json

Built-in handlers for:

Checkout Session Creation

Payment Success

Subscription Renewal

Customer Cancellations

No need to write custom middleware or webhook processors. It’s all wired up.

🔁 How the Flow Works (Stripe)

The user selects a plan on your website

The checkout session is created via Stripe API

Stripe redirects the user to a secure payment page

Upon success, EasyLaunchpad receives a webhook event

User’s plan is activated + confirmation email is sent

Logs are stored for reporting and debugging

🧾 Paddle Integration for Global Sellers

Paddle is often a better fit than Stripe for developers targeting international customers or needing EU/GST compliance.

EasyLaunchpad supports Paddle’s:

Inline Checkout and Overlay Widgets

Subscription Plans and One-Time Payments

Webhook Events (license provisioning, payment success, cancellations)

VAT/GST compliance without custom work

All integration is handled via modular service classes. You can switch or run both providers side-by-side.

🔧 Configuration Example

In appsettings.json, you simply configure:

“Payments”: {

“Provider”: “Stripe”, // or “Paddle”

“Stripe”: {

“SecretKey”: “sk_test_…”,

“PublishableKey”: “pk_test_…”

},

“Paddle”: {

“VendorId”: “123456”,

“APIKey”: “your-api-key”

}

}

The correct payment provider is loaded automatically using dependency injection via Autofac.

🧩 Admin Panel: Manage Plans Without Touching Code

EasyLaunchpad’s admin panel includes:

A visual interface to create/edit plans

Fields for price, duration, description, external plan ID (Stripe/Paddle)

Activation/deactivation toggle

Access scope definition (used to unlock features via roles or usage limits)

You can:

Add a Pro Plan for $29/month

Add a Lifetime Deal with a one-time Paddle payment

Deactivate free trial access — all without writing new logic

🧪 Webhook Events Handled Securely

Stripe and Paddle send webhook events for:

• New subscriptions
• Payment failures
• Plan cancellations
• Upgrades/downgrades

EasyLaunchpad includes secure webhook controllers to:

• Verify authenticity
• Parse payloads
• Trigger internal actions (e.g., assign new role, update access rights)
• Log and retry failed handlers using Hangfire

You get reliable, observable payment handling with no guesswork.

📬 Email Notifications

After a successful payment, EasyLaunchpad:

• Sends a confirmation email using DotLiquid templates
• Updates user records
• Logs the transaction with Serilog

The email system can be extended to send:

• Trial expiration reminders
• Invoice summaries
• Cancellation win-back campaigns

📈 Logging & Monitoring

Every payment-related action is logged with Serilog:

{

“Timestamp”: “2024–07–15T12:45:23Z”,

“Level”: “Information”,

“Message”: “User subscribed to Pro Plan via Stripe”,

“UserId”: “abc123”,

“Amount”: “29.00”

}

Hangfire queues and retries any failed webhook calls, so you never miss a critical event.
