Configure Stripe Dashboard and deployment environments.
Sets up products, prices, webhooks, and environment variables.

Stripe Configure

Set up Stripe Dashboard and deployment environment variables.

Objective

Configure everything outside the codebase: Stripe Dashboard settings, environment variables across all deployments, webhook endpoints.

Process

1. Stripe Dashboard Setup

Guide the user through (or use Stripe CLI where possible):

Products & Prices
- Create product (name matches app)
- Create price(s): monthly, annual if applicable
- Note the price IDs for env vars

Webhook Endpoint
- Create endpoint pointing to production URL
- Use canonical domain (www if that's where app lives — Stripe doesn't follow redirects)
- Enable required events (from design)
- Copy webhook signing secret

Customer Portal (if using)
- Configure allowed actions
- Set branding

2. Environment Variables

Set variables on ALL deployment targets. This is where incidents happen.

Local Development

# .env.local
STRIPE_SECRET_KEY=sk_test_...
STRIPE_WEBHOOK_SECRET=whsec_...
NEXT_PUBLIC_STRIPE_PUBLISHABLE_KEY=pk_test_...
NEXT_PUBLIC_STRIPE_PRICE_ID=price_...

Convex (both dev and prod)

# Dev
npx convex env set STRIPE_SECRET_KEY "sk_test_..."
npx convex env set STRIPE_WEBHOOK_SECRET "whsec_..."

# Prod (DON'T FORGET THIS)
npx convex env set --prod STRIPE_SECRET_KEY "sk_live_..."
npx convex env set --prod STRIPE_WEBHOOK_SECRET "whsec_..."

Vercel

vercel env add STRIPE_SECRET_KEY production
vercel env add STRIPE_WEBHOOK_SECRET production
# ... etc

3. Verify Parity

Check that all deployments have matching configuration:
- Local has test keys
- Convex dev has test keys
- Convex prod has live keys
- Vercel prod has live keys

Use verify-env-parity.sh if available, or manually compare.

4. Webhook URL Verification

CRITICAL: Verify webhook URL doesn't redirect.

curl -s -o /dev/null -w "%{http_code}" -I -X POST "https://your-domain.com/api/stripe/webhook"

Must return 4xx or 5xx, NOT 3xx. If it redirects, fix the URL in Stripe Dashboard.

Common Mistakes

• Setting env vars on dev but forgetting prod
• Using wrong domain (non-www when app is www)
• Trailing whitespace in secrets (use printf '%s' not echo)
• Test keys in production, live keys in development
