description	Implement Alipay for web and mobile with signed request safety, gateway alignment, and production-ready payment operations.
changelog	Initial release with implementation, validation, launch, and incident response playbooks for Alipay.

Setup

On first use, read setup.md and confirm platform, PSP, and release target before making code changes.

When to Use

User needs Alipay in checkout, subscriptions, or cross-border wallet flows. Agent handles architecture decisions, signing strategy, gateway integration, rollout validation, and post-launch operations.

Architecture

Memory lives in ~/alipay/. See memory-template.md for setup and status fields.

~/alipay/
|-- memory.md                 # Project snapshot, risk status, and rollout state
|-- implementations.md        # Selected approach and platform notes
|-- validation-log.md         # Test evidence and environment results
`-- incidents.md              # Failed payments, root causes, and fixes

Quick Reference

Use the smallest relevant file for the current task.

Requirements

• Environment variable: ALIPAY_APP_ID
• CLI tools for diagnostics: curl, jq
• Access to Alipay merchant console and target PSP account

Never ask users to paste private keys, full signed payloads, or PSP secrets into chat.

Data Storage

Local notes stay under ~/alipay/:

• memory file for current state and integration decisions
• validation log file for test outcomes and evidence
• incidents file for failure signatures and mitigations

Core Rules

1. Confirm Business Goal Before Choosing Integration Path

Start by identifying the target outcome:

• Higher mobile checkout conversion
• Faster repeat purchases
• Lower payment friction for domestic and cross-border users
• Fewer payment failures

Then choose one primary path:

• Web or H5 checkout with Alipay gateway redirect flow
• In-app checkout with Alipay SDK handoff
• PSP-mediated integration path

Do not mix paths in one patch unless the user asks for a migration plan.

2. Require Merchant and Environment Prerequisites

Before implementation, confirm:

• Alipay app id exists for the correct account
• Gateway keys and certificates match the environment
• Notify and return URLs are configured and reachable
• Test and production credentials are separated

If prerequisites are missing, pause coding and produce a concrete prerequisite checklist.

3. Enforce Server Truth for Amounts and Currency

Amounts and currency must match across:

• Client payment request payload
• Server-side order totals
• Alipay authorization and capture calls

Never trust client totals for final charge amount.

4. Make Signing and Callback Verification Explicit

Treat signing and verification as required controls:

• Sign outgoing requests with the approved key strategy
• Verify callback signatures before changing order state
• Reject unsigned or invalid callbacks deterministically

Never mark a payment successful before signature checks pass.

5. Keep Payment Payload Handling Minimal and Auditable

Treat Alipay payloads as sensitive:

• Forward payload only to backend or PSP
• Persist metadata only (request id, status, amount, currency)
• Never store raw signed payloads in logs, notes, or screenshots

6. Build Idempotent and Recoverable Payment Steps

Require idempotency and reconciliation for all critical calls:

• Authorization request
• Capture request
• Refund or close operations

Every retried request must reuse stable idempotency keys to prevent duplicates.

7. Separate Test and Production Release Gates

Do not recommend production rollout until all gates pass:

• Test success, decline, cancellation, and timeout paths are covered
• Device and browser matrix is complete for supported audience
• Fallback card or alternative checkout works when Alipay is unavailable
• Failure observability and alerts are active

Common Traps

• Shipping test gateway config to production -> live checkout failures
• Skipping callback signature verification -> fraudulent or duplicated state transitions
• Mismatching charset or signing parameters -> request rejection at gateway
• Trusting client totals -> mismatch between authorized and captured amounts
• Missing idempotency on retries -> duplicate charges and refund overhead
• Launching without fallback checkout -> conversion loss when wallet is unavailable

External Endpoints

Endpoint	Data Sent	Purpose
https://openapi.alipay.com/gateway.do	Signed payment requests and metadata	Production Alipay gateway operations
https://openapi-sandbox.dl.alipaydev.com/gateway.do	Signed payment requests and metadata	Sandbox validation and integration testing
https://global.alipay.com	Documentation and account console traffic	Merchant setup and operational reference

No other data should be sent externally unless the selected PSP requires it.

Security & Privacy

Data that leaves your machine:

• Alipay request payloads needed for wallet flow
• Payment metadata and signed requests sent to configured PSP or backend

Data that stays local:

• Integration notes and rollout state under ~/alipay/
• Validation evidence and failure logs without raw signed payloads

This skill does NOT:

• Store raw signed request payloads in memory files
• Skip mandatory merchant and callback verification requirements
• Enable production release without explicit readiness checks

Trust

Alipay integrations depend on Alipay infrastructure and the chosen PSP. Only install and run this skill if you trust those services and your payment backend.
