# Koha Donation System - Stripe Setup Guide
|
||||
|
||||
**Project:** Tractatus Framework
|
||||
**Feature:** Phase 3 - Koha (Donation) System
|
||||
**Date:** 2025-10-08
|
||||
**Status:** Development
|
||||
|
||||
---
|
||||
|
||||
## Overview
|
||||
|
||||
The Koha donation system uses the existing Stripe account from `passport-consolidated` to process donations in NZD (New Zealand Dollars). This document guides you through setting up the required Stripe products and webhooks.
|
||||
|
||||
**Account:** Same Stripe test account as passport-consolidated
|
||||
**Currency:** NZD (New Zealand Dollars)
|
||||
**Payment Types:** Recurring monthly subscriptions + one-time donations
|
||||
|
||||
---
|
||||
|
||||
## 1. Stripe Products to Create
|
||||
|
||||
### Product: "Tractatus Framework Support"
|
||||
|
||||
**Description:** "Support the development and maintenance of the Tractatus AI Safety Framework. Your donation helps fund hosting, development, research, and community building."
|
||||
|
||||
**Statement Descriptor:** "TRACTATUS FRAMEWORK"
|
||||
**Category:** Charity/Non-profit
|
||||
|
||||
---
|
||||
|
||||
## 2. Price IDs to Create
|
||||
|
||||
### 2.1 Monthly Tier: $5 NZD/month
|
||||
|
||||
```
|
||||
Product: Tractatus Framework Support
|
||||
Price: $5.00 NZD
|
||||
Billing: Recurring - Monthly
|
||||
ID: price_<generated_by_stripe>
|
||||
```
|
||||
|
||||
**After creation, copy the Price ID and update .env:**
|
||||
```bash
|
||||
STRIPE_KOHA_5_PRICE_ID=price_<your_actual_price_id>
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### 2.2 Monthly Tier: $15 NZD/month
|
||||
|
||||
```
|
||||
Product: Tractatus Framework Support
|
||||
Price: $15.00 NZD
|
||||
Billing: Recurring - Monthly
|
||||
ID: price_<generated_by_stripe>
|
||||
```
|
||||
|
||||
**After creation, copy the Price ID and update .env:**
|
||||
```bash
|
||||
STRIPE_KOHA_15_PRICE_ID=price_<your_actual_price_id>
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### 2.3 Monthly Tier: $50 NZD/month
|
||||
|
||||
```
|
||||
Product: Tractatus Framework Support
|
||||
Price: $50.00 NZD
|
||||
Billing: Recurring - Monthly
|
||||
ID: price_<generated_by_stripe>
|
||||
```
|
||||
|
||||
**After creation, copy the Price ID and update .env:**
|
||||
```bash
|
||||
STRIPE_KOHA_50_PRICE_ID=price_<your_actual_price_id>
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### 2.4 One-Time Donation (Custom Amount)
|
||||
|
||||
**Note:** For one-time donations, we don't create a fixed price. Instead, the donation form sends a custom amount to Stripe Checkout. No Price ID needed for this - the code handles it dynamically.
|
||||
|
||||
---
|
||||
|
||||
## 3. Webhook Configuration
|
||||
|
||||
### Create Webhook Endpoint
|
||||
|
||||
**URL (Development):**
|
||||
```
|
||||
http://localhost:9000/api/koha/webhook
|
||||
```
|
||||
|
||||
**URL (Production):**
|
||||
```
|
||||
https://agenticgovernance.digital/api/koha/webhook
|
||||
```
|
||||
|
||||
### Events to Subscribe To
|
||||
|
||||
Select these events in Stripe Dashboard:
|
||||
|
||||
- ✅ `checkout.session.completed`
|
||||
- ✅ `payment_intent.succeeded`
|
||||
- ✅ `payment_intent.payment_failed`
|
||||
- ✅ `invoice.paid` (recurring payments)
|
||||
- ✅ `invoice.payment_failed`
|
||||
- ✅ `customer.subscription.created`
|
||||
- ✅ `customer.subscription.updated`
|
||||
- ✅ `customer.subscription.deleted`
|
||||
|
||||
### After Creating Webhook
|
||||
|
||||
Copy the **Webhook Signing Secret** and update .env:
|
||||
|
||||
```bash
|
||||
STRIPE_KOHA_WEBHOOK_SECRET=whsec_<your_webhook_secret>
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 4. Testing Configuration
|
||||
|
||||
### Stripe Test Cards
|
||||
|
||||
Use these test cards for development:
|
||||
|
||||
| Card Number | Scenario |
|
||||
|---------------------|----------------------------|
|
||||
| 4242 4242 4242 4242 | Successful payment |
|
||||
| 4000 0027 6000 3184 | 3D Secure required |
|
||||
| 4000 0000 0000 9995 | Payment declined |
|
||||
| 4000 0000 0000 0341 | Attaching card fails |
|
||||
|
||||
**Expiry:** Any future date
|
||||
**CVC:** Any 3 digits
|
||||
**ZIP:** Any valid postal code
|
||||
|
||||

|
||||
|
||||

|
||||
|
||||
## 6. Environment Variables Checklist
|
||||
|
||||
After setup, your `.env` should have:
|
||||
|
||||
```bash
|
||||
# Stripe Keys (from passport-consolidated)
|
||||
STRIPE_SECRET_KEY=sk_test_51RX67k...
|
||||
STRIPE_PUBLISHABLE_KEY=pk_test_51RX67k...
|
||||
|
||||
# Webhook Secret (from Step 4)
|
||||
STRIPE_KOHA_WEBHOOK_SECRET=whsec_...
|
||||
|
||||
# Price IDs (from Step 3)
|
||||
STRIPE_KOHA_5_PRICE_ID=price_...
|
||||
STRIPE_KOHA_15_PRICE_ID=price_...
|
||||
STRIPE_KOHA_50_PRICE_ID=price_...
|
||||
|
||||
# Frontend URL
|
||||
FRONTEND_URL=http://localhost:9000
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 7. Testing the Integration
|
||||
|
||||
### Test API Endpoint
|
||||
|
||||
```bash
|
||||
curl -X POST http://localhost:9000/api/koha/checkout \
|
||||
-H "Content-Type: application/json" \
|
||||
-d '{
|
||||
"amount": 1500,
|
||||
"frequency": "monthly",
|
||||
"tier": "15",
|
||||
"donor": {
|
||||
"name": "Test Donor",
|
||||
"email": "test@example.com"
|
||||
},
|
||||
"public_acknowledgement": false
|
||||
}'
|
||||
```
|
||||
|
||||
**Expected Response:**
|
||||
```json
|
||||
{
|
||||
"success": true,
|
||||
"data": {
|
||||
"sessionId": "cs_test_...",
|
||||
"checkoutUrl": "https://checkout.stripe.com/c/pay/cs_test_...",
|
||||
"frequency": "monthly",
|
||||
"amount": 15
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Test Webhook Locally
|
||||
|
||||
Use Stripe CLI for local webhook testing:
|
||||
|
||||
```bash
|
||||
# Install Stripe CLI
|
||||
brew install stripe/stripe-cli/stripe
|
||||
|
||||
# Forward webhooks to local server
|
||||
stripe listen --forward-to localhost:9000/api/koha/webhook
|
||||
|
||||
# Trigger test event
|
||||
stripe trigger checkout.session.completed
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 8. Production Setup
|
||||
|
||||
### Before Going Live
|
||||
|
||||
1. **Switch to Live Mode** in Stripe Dashboard
|
||||
2. **Create live webhook** endpoint:
|
||||
- URL: `https://agenticgovernance.digital/api/koha/webhook`
|
||||
- Same 8 events as development
|
||||
3. **Obtain live API keys** (starts with `sk_live_` and `pk_live_`)
|
||||
4. **Update production .env** with live keys
|
||||
5. **Test with real card** (small amount)
|
||||
6. **Verify webhook delivery** in Stripe Dashboard
|
||||
|
||||
### Production Environment Variables
|
||||
|
||||
```bash
|
||||
NODE_ENV=production
|
||||
STRIPE_SECRET_KEY=sk_live_...
|
||||
STRIPE_PUBLISHABLE_KEY=pk_live_...
|
||||
STRIPE_KOHA_WEBHOOK_SECRET=whsec_live_...
|
||||
FRONTEND_URL=https://agenticgovernance.digital
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 9. Monitoring & Troubleshooting
|
||||
|
||||
### Check Webhook Deliveries
|
||||
|
||||
1. Stripe Dashboard → **Developers** → **Webhooks**
|
||||
2. Click on your endpoint
|
||||
3. View **Recent deliveries**
|
||||
4. Check for failed deliveries (red icons)
|
||||
|
||||
### Common Issues
|
||||
|
||||
| Issue | Solution |
|
||||
|-------|----------|
|
||||
| Webhook signature verification fails | Ensure `STRIPE_KOHA_WEBHOOK_SECRET` matches Dashboard |
|
||||
| Price ID not found | Verify Price IDs in `.env` match Stripe Dashboard |
|
||||
| Redirects fail after payment | Check `FRONTEND_URL` is correct |
|
||||
| Donations not recording | Check MongoDB connection and logs |
|
||||
|
||||
### Debug Logging
|
||||
|
||||
Enable detailed Stripe logs:
|
||||
|
||||
```bash
|
||||
# In koha.service.js, logger.info statements will show:
|
||||
[KOHA] Creating checkout session: monthly donation of NZD $15.00
|
||||
[KOHA] Checkout session created: cs_test_...
|
||||
[KOHA] Processing webhook event: checkout.session.completed
|
||||
[KOHA] Donation recorded: NZD $15.00
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 10. Security Considerations
|
||||
|
||||
### Webhook Security
|
||||
|
||||
- ✅ Signature verification enabled (via `verifyWebhookSignature`)
|
||||
- ✅ Raw body parsing for Stripe webhooks
|
||||
- ✅ HTTPS required in production
|
||||
- ✅ Rate limiting on API endpoints
|
||||
|
||||
### Data Privacy
|
||||
|
||||
- ✅ Donor emails stored securely (for receipts only)
|
||||
- ✅ Anonymous donations by default
|
||||
- ✅ Opt-in public acknowledgement
|
||||
- ✅ No credit card data stored (handled by Stripe)
|
||||
|
||||
### PCI Compliance
|
||||
|
||||
- ✅ Using Stripe Checkout (PCI compliant)
|
||||
- ✅ No card data touches our servers
|
||||
- ✅ Stripe handles all payment processing
|
||||
|
||||
---
|
||||
|
||||
## 11. Next Steps
|
||||
|
||||
After completing this setup:
|
||||
|
||||
1. ✅ Test donation flow end-to-end
|
||||
2. ✅ Create frontend donation form UI
|
||||
3. ✅ Build transparency dashboard
|
||||
4. ✅ Implement receipt email generation
|
||||
5. ✅ Add donor acknowledgement system
|
||||
6. ⏳ Deploy to production
