Processor connections stay visible
Operators can inspect Stripe, PayPal, TaxJar, Avalara, test-mode routing, and integration state before checkout traffic goes live.
Security
Security at Plandalf
Checkout is one of the most sensitive surfaces in an internet business. Plandalf keeps payment data with Stripe or PayPal, while Offers, integrations, API paths, webhooks, invoices, and Automations stay inspectable.
The security review starts with the product surfaces
A useful security page should point buyers to the actual places where payment processors, API keys, webhooks, invoices, integrations, and purchase records are configured or inspected.
API and webhook paths are documented
Custom builds should use API authentication, SDK checkout, and signed webhooks instead of spreading purchase context across untracked scripts.
Invoices and records remain traceable
Purchase records, invoices, products, payment state, and customer context should remain inspectable after the charge is complete.
Automations keep the handoff inspectable
Automations, sequences, and webhooks keep purchase events tied to buyer, product, invoice, payment, coupon, and fulfillment context.
Team access is a launch control
Team members, scoped access, notifications, preview sessions, and test sessions help keep checkout launch work accountable.
Tax and invoice settings stay attached
Tax settings, Avalara, TaxJar, payment processors, PDF invoices, and invoice email behavior should stay connected to the offer and buyer record.
Implementation docs are part of the control surface
API references, SDK checkout, webhook fanout, customer identity, metadata, and custom API integrations give reviewers a path from claim to implementation.
Practical security principles for commerce workflows
These are the operating paths a builder or reviewer should check before launch: payment data, access, event verification, and system status.
Payment data belongs with the processor Card details go to Stripe or PayPal. Plandalf keeps the offer, checkout, invoice, payment state, and follow-up context around the transaction. Access should be scoped and inspectable Use team members, API authentication, revocable tokens, and documented SDK paths so internal and agent-built workflows do not depend on mystery credentials. Events should be verifiable Use webhooks, sequences, and Automations when purchase events need to update CRM, email, fulfilment, records, support, or reporting systems. Operators need a status path Security work includes knowing whether checkout, API, webhooks, integrations, Stripe, and PayPal are operational before a campaign launches. Finance context should be traceable Tax settings, invoice records, refunds, customer history, payment state, and support handoff should not require processor exports to reconstruct. Developer paths should be documented API references, SDK checkout, webhooks, customer identify, metadata, and custom API integrations should be one click from the security review.
