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 .NET Core Boilerplate includes a fully integrated payment module with support for Stripe and Paddle — out of the box.
In this blog, we’ll walk you through how EasyLaunchpad .NET Core Boilerplate 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 appears to be 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 .NET Core boilerplate solves this by offering a turnkey payment solution that integrates Stripe and Paddle seamlessly into the backend logic and your admin panel.
⚙️ What’s Included in the Payment Module?
The EasyLaunchpad .NET Core boilerplate 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 .NET Core boilerplate 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 the 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 .NET Core boilerplate 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 .NET Core boilerplate’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 .NET Core boilerplate 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 .NET Core boilerplate:
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.
