Use it when the operator needs the upstream workflow, support files, and repository context to stay intact while the public validator and private enhancer continue their normal downstream flow. This intake keeps the copied upstream files intact and uses the `external_source` block in `metadata.json` plus `ORIGIN.md` as the provenance anchor for review. # Stripe Integration Master Stripe payment processing integration for robust, PCI-compliant payment flows including checkout, subscriptions, webhooks, and refunds. Imported source sections that did not map cleanly to the public headings are still preserved below or in the support files. Notable imported sections: Core Concepts, Payment Implementation Patterns, Webhook Handling, Customer Management, Refund Handling, Testing. ## When to Use This Skill Use this section as the trigger filter. It should make the activation boundary explicit before the operator loads files, runs commands, or opens a pull request. - The task is unrelated to stripe integration - You need a different domain or tool outside this scope - Implementing payment processing in web/mobile applications - Setting up subscription billing systems - Handling one-time payments and recurring charges - Processing refunds and disputes ## Operating Table | Situation | Start here | Why it matters | | --- | --- | --- | | First-time use | `metadata.json` | Confirms repository, branch, commit, and imported path through the `external_source` block before touching the copied workflow | | Provenance review | `ORIGIN.md` | Gives reviewers a plain-language audit trail for the imported source | | Workflow execution | `SKILL.md` | Starts with the smallest copied file that materially changes execution | | Supporting context | `SKILL.md` | Adds the next most relevant copied source file without loading the entire package | | Handoff decision | `## Related Skills` | Helps the operator switch to a stronger native skill when the task drifts | ## Workflow This workflow is intentionally editorial and operational at the same time. It keeps the imported source useful to the operator while still satisfying the public intake standards that feed the downstream enhancer flow. 1. Clarify goals, constraints, and required inputs. 2. Apply relevant best practices and validate outcomes. 3. Provide actionable steps and verification. 4. If detailed examples are required, open resources/implementation-playbook.md. 5. Confirm the user goal, the scope of the imported workflow, and whether this skill is still the right router for the task. 6. Read the overview and provenance files before loading any copied upstream support files. 7. Load only the references, examples, prompts, or scripts that materially change the outcome for the current request. ### Imported Workflow Notes #### Imported: Instructions - Clarify goals, constraints, and required inputs. - Apply relevant best practices and validate outcomes. - Provide actionable steps and verification. - If detailed examples are required, open `resources/implementation-playbook.md`. #### Imported: Core Concepts ### 1. Payment Flows **Checkout Session (Hosted)** - Stripe-hosted payment page - Minimal PCI compliance burden - Fastest implementation - Supports one-time and recurring payments **Payment Intents (Custom UI)** - Full control over payment UI - Requires Stripe.js for PCI compliance - More complex implementation - Better customization options **Setup Intents (Save Payment Methods)** - Collect payment method without charging - Used for subscriptions and future payments - Requires customer confirmation ### 2. Webhooks **Critical Events:** - `payment_intent.succeeded`: Payment completed - `payment_intent.payment_failed`: Payment failed - `customer.subscription.updated`: Subscription changed - `customer.subscription.deleted`: Subscription canceled - `charge.refunded`: Refund processed - `invoice.payment_succeeded`: Subscription payment successful ### 3. Subscriptions **Components:** - **Product**: What you're selling - **Price**: How much and how often - **Subscription**: Customer's recurring payment - **Invoice**: Generated for each billing cycle ### 4. Customer Management - Create and manage customer records - Store multiple payment methods - Track customer metadata - Manage billing details ## Examples ### Example 1: Ask for the upstream workflow directly ```text Use @stripe-integration-v6 to handle . Start from the copied upstream workflow, load only the files that change the outcome, and keep provenance visible in the answer. ``` **Explanation:** This is the safest starting point when the operator needs the imported workflow, but not the entire repository. ### Example 2: Ask for a provenance-grounded review ```text Review @stripe-integration-v6 against metadata.json and ORIGIN.md, then explain which copied upstream files you would load first and why. ``` **Explanation:** Use this before review or troubleshooting when you need a precise, auditable explanation of origin and file selection. ### Example 3: Narrow the copied support files before execution ```text Use @stripe-integration-v6 for . Load only the copied references, examples, or scripts that change the outcome, and name the files explicitly before proceeding. ``` **Explanation:** This keeps the skill aligned with progressive disclosure instead of loading the whole copied package by default. ### Example 4: Build a reviewer packet ```text Review @stripe-integration-v6 using the copied upstream files plus provenance, then summarize any gaps before merge. ``` **Explanation:** This is useful when the PR is waiting for human review and you want a repeatable audit packet. ### Imported Usage Notes #### Imported: Quick Start ```python import stripe stripe.api_key = "sk_test_..." # Create a checkout session session = stripe.checkout.Session.create( payment_method_types=['card'], line_items=[{ 'price_data': { 'currency': 'usd', 'product_data': { 'name': 'Premium Subscription', }, 'unit_amount': 2000, # $20.00 'recurring': { 'interval': 'month', }, }, 'quantity': 1, }], mode='subscription', success_url='https://yourdomain.com/success?session_id={CHECKOUT_SESSION_ID}', cancel_url='https://yourdomain.com/cancel', ) # Redirect user to session.url print(session.url) ``` ## Best Practices Treat the generated public skill as a reviewable packaging layer around the upstream repository. The goal is to keep provenance explicit and load only the copied source material that materially improves execution. - Always Use Webhooks: Don't rely solely on client-side confirmation - Idempotency: Handle webhook events idempotently - Error Handling: Gracefully handle all Stripe errors - Test Mode: Thoroughly test with test keys before production - Metadata: Use metadata to link Stripe objects to your database - Monitoring: Track payment success rates and errors - PCI Compliance: Never handle raw card data on your server ### Imported Operating Notes #### Imported: Best Practices 1. **Always Use Webhooks**: Don't rely solely on client-side confirmation 2. **Idempotency**: Handle webhook events idempotently 3. **Error Handling**: Gracefully handle all Stripe errors 4. **Test Mode**: Thoroughly test with test keys before production 5. **Metadata**: Use metadata to link Stripe objects to your database 6. **Monitoring**: Track payment success rates and errors 7. **PCI Compliance**: Never handle raw card data on your server 8. **SCA Ready**: Implement 3D Secure for European payments ## Troubleshooting ### Problem: The operator skipped the imported context and answered too generically **Symptoms:** The result ignores the upstream workflow in `plugins/antigravity-bundle-startup-founder/skills/stripe-integration`, fails to mention provenance, or does not use any copied source files at all. **Solution:** Re-open `metadata.json`, `ORIGIN.md`, and the most relevant copied upstream files. Check the `external_source` block first, then restate the provenance before continuing. ### Problem: The imported workflow feels incomplete during review **Symptoms:** Reviewers can see the generated `SKILL.md`, but they cannot quickly tell which references, examples, or scripts matter for the current task. **Solution:** Point at the exact copied references, examples, scripts, or assets that justify the path you took. If the gap is still real, record it in the PR instead of hiding it. ### Problem: The task drifted into a different specialization **Symptoms:** The imported skill starts in the right place, but the work turns into debugging, architecture, design, security, or release orchestration that a native skill handles better. **Solution:** Use the related skills section to hand off deliberately. Keep the imported provenance visible so the next skill inherits the right context instead of starting blind. ## Related Skills - `@competitive-landscape-v3` - Use when the work is better handled by that native specialization after this imported skill establishes context. - `@competitor-alternatives-v3` - Use when the work is better handled by that native specialization after this imported skill establishes context. - `@copywriting-v3` - Use when the work is better handled by that native specialization after this imported skill establishes context. - `@cpp-pro-v3` - Use when the work is better handled by that native specialization after this imported skill establishes context. ## Additional Resources Use this support matrix and the linked files below as the operator packet for this imported skill. They should reflect real copied source material, not generic scaffolding. | Resource family | What it gives the reviewer | Example path | | --- | --- | --- | | `references` | copied reference notes, guides, or background material from upstream | `references/n/a` | | `examples` | worked examples or reusable prompts copied from upstream | `examples/n/a` | | `scripts` | upstream helper scripts that change execution or validation | `scripts/n/a` | | `agents` | routing or delegation notes that are genuinely part of the imported package | `agents/n/a` | | `assets` | supporting assets or schemas copied from the source package | `assets/n/a` | ### Imported Reference Notes #### Imported: Resources - **references/checkout-flows.md**: Detailed checkout implementation - **references/webhook-handling.md**: Webhook security and processing - **references/subscription-management.md**: Subscription lifecycle - **references/customer-management.md**: Customer and payment method handling - **references/invoice-generation.md**: Invoicing and billing - **assets/stripe-client.py**: Production-ready Stripe client wrapper - **assets/webhook-handler.py**: Complete webhook processor - **assets/checkout-config.json**: Checkout configuration templates #### Imported: Payment Implementation Patterns ### Pattern 1: One-Time Payment (Hosted Checkout) ```python def create_checkout_session(amount, currency='usd'): """Create a one-time payment checkout session.""" try: session = stripe.checkout.Session.create( payment_method_types=['card'], line_items=[{ 'price_data': { 'currency': currency, 'product_data': { 'name': 'Purchase', 'images': ['https://example.com/product.jpg'], }, 'unit_amount': amount, # Amount in cents }, 'quantity': 1, }], mode='payment', success_url='https://yourdomain.com/success?session_id={CHECKOUT_SESSION_ID}', cancel_url='https://yourdomain.com/cancel', metadata={ 'order_id': 'order_123', 'user_id': 'user_456' } ) return session except stripe.error.StripeError as e: # Handle error print(f"Stripe error: {e.user_message}") raise ``` ### Pattern 2: Custom Payment Intent Flow ```python def create_payment_intent(amount, currency='usd', customer_id=None): """Create a payment intent for custom checkout UI.""" intent = stripe.PaymentIntent.create( amount=amount, currency=currency, customer=customer_id, automatic_payment_methods={ 'enabled': True, }, metadata={ 'integration_check': 'accept_a_payment' } ) return intent.client_secret # Send to frontend # Frontend (JavaScript) """ const stripe = Stripe('pk_test_...'); const elements = stripe.elements(); const cardElement = elements.create('card'); cardElement.mount('#card-element'); const {error, paymentIntent} = await stripe.confirmCardPayment( clientSecret, { payment_method: { card: cardElement, billing_details: { name: 'Customer Name' } } } ); if (error) { // Handle error } else if (paymentIntent.status === 'succeeded') { // Payment successful } """ ``` ### Pattern 3: Subscription Creation ```python def create_subscription(customer_id, price_id): """Create a subscription for a customer.""" try: subscription = stripe.Subscription.create( customer=customer_id, items=[{'price': price_id}], payment_behavior='default_incomplete', payment_settings={'save_default_payment_method': 'on_subscription'}, expand=['latest_invoice.payment_intent'], ) return { 'subscription_id': subscription.id, 'client_secret': subscription.latest_invoice.payment_intent.client_secret } except stripe.error.StripeError as e: print(f"Subscription creation failed: {e}") raise ``` ### Pattern 4: Customer Portal ```python def create_customer_portal_session(customer_id): """Create a portal session for customers to manage subscriptions.""" session = stripe.billing_portal.Session.create( customer=customer_id, return_url='https://yourdomain.com/account', ) return session.url # Redirect customer here ``` #### Imported: Webhook Handling ### Secure Webhook Endpoint ```python from flask import Flask, request import stripe app = Flask(__name__) endpoint_secret = 'whsec_...' @app.route('/webhook', methods=['POST']) def webhook(): payload = request.data sig_header = request.headers.get('Stripe-Signature') try: event = stripe.Webhook.construct_event( payload, sig_header, endpoint_secret ) except ValueError: #

Notify customer # Update order status def handle_subscription_canceled(subscription): """Handle subscription cancellation.""" customer_id = subscription['customer'] # Update user access # Send cancellation email print(f"Subscription canceled: {subscription['id']}") ``` ### Webhook Best Practices ```python import hashlib import hmac def verify_webhook_signature(payload, signature, secret): """Manually verify webhook signature.""" expected_sig = hmac.new( secret.encode('utf-8'), payload, hashlib.sha256 ).hexdigest() return hmac.compare_digest(signature, expected_sig) def handle_webhook_idempotently(event_id, handler): """Ensure webhook is processed exactly once.""" # Check if event already processed if is_event_processed(event_id): return # Process event try: handler() mark_event_processed(event_id) except Exception as e: log_error(e) # Stripe will retry failed webhooks raise ``` #### Imported: Customer Management ```python def create_customer(email, name, payment_method_id=None): """Create a Stripe customer.""" customer = stripe.Customer.create( email=email, name=name, payment_method=payment_method_id, invoice_settings={ 'default_payment_method': payment_method_id } if payment_method_id else None, metadata={ 'user_id': '12345' } ) return customer def attach_payment_method(customer_id, payment_method_id): """Attach a payment method to a customer.""" stripe.PaymentMethod.attach( payment_method_id, customer=customer_id ) #
