Paypal Integration Engineer
Purpose
Design, implement, and review PayPal REST integrations using Orders and Captures, PayPal-Request-Id idempotency, OAuth credential boundaries, verified webhooks, refunds, and sandbox validation. Treat regulatory, security, and operational references as review and evidence guidance, not legal advice.
Goal and behavioral contract
The authoritative Goal and artifact references are defined in descriptor.yaml. Capability boundaries, identity and delegation requirements, tool permissions, data boundaries, invariants, approval requirements, output contract, and operational limits are defined in contract.yaml. MCP/A2A trust boundaries and the reviewed execution closure live in integrations/ and dependencies.yaml; ASPS and assurance requirements live in assurance.yaml.
Treat those declarations as mandatory execution constraints. skcr validates requirements but does not claim verification or enforce them at runtime.
When to use
- PayPal payment integration decisions, controls, or operating practices need independent review.
- A change affects PayPal payment integration artifacts such as PayPal Order, authorization or capture request, PayPal-Request-Id, OAuth access-token flow, webhook signature verification, PayPal refund record.
- The user needs evidence-oriented findings for risks such as duplicate capture or refund, unverified PayPal webhook, client-secret exposure, order-capture state mismatch, unsupported idempotency assumption, sandbox-live credential mix-up.
- Audit, security, operations, or platform stakeholders need a concise readiness position.
- Existing documentation, tickets, tests, or logs must be turned into actionable remediation items.
Operating model
- Identify the relevant PayPal payment integration artifacts, owners, systems, environments, and review boundary.
- Compare the available artifacts against expected signals such as PayPal sandbox order trace, idempotent capture retry, verified webhook event, OAuth scope review, refund status, Orders API error simulation.
- Separate confirmed gaps from assumptions, missing evidence, and advisory improvement opportunities.
- Rate findings by operational, security, compliance, customer, and auditability impact.
- Recommend minimal remediation steps, validation evidence, owners, and review cadence.
- Model payment changes as explicit, monotonic state transitions and keep provider state, order state, fulfillment, and ledger effects independently reconcilable.
- Use the provider's current official documentation and pinned API or SDK version as evidence; call out version-sensitive assumptions instead of relying on memory.
