Official merchant\u002Fdeveloper integration docs (versioned if possible).\n2. Environment base URLs (sandbox and production).\n3. Auth\u002Fsignature method and exact verification steps.\n4. Webhook\u002Fevent payload examples and retry semantics.\n5. Settlement and payout timing docs.\n6. Merchant contract constraints (supported payment methods, limits, recurring support, refunds).\nIf any of these are missing, respond with:\n`UNSPECIFIED: Missing or unverified dependency`\nDo not fabricate field names, signatures, or API routes.\n## Verified Context (Public, High-Level)\n- **JazzCash Online Payment Gateway** publicly states hosted checkout, multiple methods (cards\u002Fmobile account\u002Fvoucher\u002Fdirect debit), integration support, and merchant portal for transaction monitoring\u002Freconciliation.\n- **Easypay Integration Guides** publicly expose multiple payment method categories (for example OTC\u002FMA\u002FCC\u002FIB\u002FQR\u002FTill\u002FDD).\n- **SBP PSO\u002FPSP framework** governs payment operators\u002Fproviders under Pakistan?s payment systems regime.\n- **SBP Raast DFS pages** describe interoperable QR-based P2P and P2M rails and the countrywide standard.\nUse these as landscape context only. Use provider-issued merchant docs for implementation details.\n## When to Use This Skill\nUse this skill when:\n- Building PKR-first SaaS\u002FB2B billing for Pakistan.\n- Adding JazzCash\u002FEasypaisa\u002Fbank-PSP rails to an existing product.\n- Implementing payment reliability controls (webhooks, retries, idempotency, reconciliation).\n- Designing auditable billing operations (finance\u002Fsupport-grade reporting).\n## Do Not Use This Skill When\nDo not use this skill when:\n- The task is only global card processing (use Stripe\u002Fglobal gateway skills).\n- No Pakistan market\u002Fpayment scope exists.\n- The request is purely pricing strategy with no payment infrastructure work.\n- The user asks for legal\u002Ftax advice (provide risk flags and recommend local counsel).\n## Architecture Boundary (Required)\nImplement a payment boundary instead of scattering provider logic across UI\u002Froutes.\nCore components:\n- `ClientApp` (checkout\u002Fbilling UI)\n- `BackendAPI` (server routes)\n- `PaymentsService` (provider abstraction)\n- `WebhookIngest` (provider callbacks)\n- `BillingDB` (source of record)\n- `ReconciliationJob` (daily settlement verification)\nHigh-level flow:\n```mermaid\nflowchart LR\n  client[ClientApp] --> api[BackendAPI]\n  api --> svc[PaymentsService]\n  svc --> jazz[JazzCash Adapter]\n  svc --> easy[Easypaisa Adapter]\n  svc --> bank[Bank\u002FPSP Adapter]\n  svc --> raast[Raast\u002FQR Adapter Optional]\n  jazz --> hook[WebhookIngest]\n  easy --> hook\n  bank --> hook\n  raast --> hook\n  hook --> db[BillingDB]\n  db --> recon[ReconciliationJob] ``` \n\nData Model Requirements\nUse smallest currency unit (Rupee) as integer.\n\nMinimum entities:\n- customers\n- subscriptions (if applicable)\n- invoices\n- payments\n- payment_events (immutable event log)\n- refunds \u002F adjustments\n- reconciliation_runs\n- reconciliation_items\npayments must include:\n- tenant_id\n- provider\n- provider_payment_id\n- amount_rupee\n- currency = PKR\n- status (pending|succeeded|failed|refunded|canceled)\n- idempotency_key\n- provider_raw (JSON)\n- created_at, updated_at\nProvider Abstraction Contract (Example)\nexport type ProviderName = \"jazzcash\" | \"easypaisa\" | \"bank-gateway\" | \"raast\";\nexport interface CreatePaymentParams {\n  provider: ProviderName;\n  amountPaisa: number; \u002F\u002F PKR in rupee\n  currency: \"PKR\";\n  customerId: string;\n  invoiceId?: string;\n  successUrl: string;\n  failureUrl: string;\n  metadata?: Record\u003Cstring, string>;\n}\nexport interface CreatePaymentResult {\n  paymentId: string;        \u002F\u002F internal id\n  redirectUrl?: string;     \u002F\u002F hosted flow\n  deepLinkUrl?: string;     \u002F\u002F app flow\n  qrPayload?: string;       \u002F\u002F optional\n}\nexport interface PaymentsService {\n  createPayment(params: CreatePaymentParams): Promise\u003CCreatePaymentResult>;\n  verifyAndHandleWebhook(rawBody: string, headers: Record\u003Cstring, string>): Promise\u003Cvoid>;\n}\nWebhook Handling Rules (Non-Negotiable)\n1. Verify signature from raw body.\n2. Resolve stable provider_payment_id.\n3. Enforce idempotency with DB guard (unique index on provider event id where available).\n4. Update payment\u002Finvoice state inside a transaction.\n5. Emit domain event after committed state transition.\n6. Return provider-expected HTTP response quickly; defer heavy work to queue.\nNever mark succeeded from client redirect alone.\nReconciliation and Finance Controls\nRun daily reconciliation per provider:\n- Pull transaction data via provider API\u002Fexport\u002Fportal method.\n- Match by provider_payment_id, amount, and date window.\n- Classify mismatches:\n  - provider success + local pending\n  - local success + provider missing\u002Freversed\n  - amount mismatch\n- Persist run artifacts and unresolved items.\n- Generate per-tenant and per-provider summaries.\nRecurring Billing Caveat\nDo not assume wallet\u002Fdirect-debit recurring capability is universally available.\nFor subscriptions:\n- Prefer invoice + pay-link workflow unless provider docs and merchant contract explicitly confirm recurring\u002Fautopay support.\n- If recurring is supported, implement mandate lifecycle and failure handling per documented provider rules.\nSecurity and Operations Checklist\n- Separate sandbox\u002Flive credentials.\n- Rotate keys and store in secure secret manager.\n- Add request correlation IDs.\n- Keep immutable payment event logs.\n- Alert on webhook signature failures and reconciliation deltas.\n- Implement retry policy with bounded exponential backoff.\n- Maintain runbooks for payment support and incident response.\nCompliance Note\nThis skill provides engineering guidance, not legal advice.\nAlways include this line in production recommendations:\n?Validate this implementation with qualified legal\u002Faccounting advisors in Pakistan and ensure alignment with current SBP and contractual provider requirements before go-live.?\nOutput Format for User Requests\nFor implementation requests, respond with:\n1. Assumptions explicitly marked as verified\u002Funverified.\n2. Required missing inputs (merchant docs, signatures, webhook schema).\n3. Proposed architecture and schema deltas.\n4. Minimal implementation plan (ordered, testable).\n5. Idempotency + reconciliation strategy.\n6. Go-live checklist and rollback plan.\nIf required provider facts are missing, stop and return:\nUNSPECIFIED: Missing or unverified dependency\n\nRelated Skills\n- @stripe-integration\n- @analytics-tracking\n- @pricing-strategy\n- @senior-fullstack\n\n**Suggested references to keep in your skill docs (for provenance)**\n- JazzCash OPG: `https:\u002F\u002Fwww.jazzcash.com.pk\u002Fcorporate\u002Fonline-payment-gateway\u002F`\n- Easypay integration guides: `https:\u002F\u002Feasypay.easypaisa.com.pk\u002Feasypay-merchant\u002Ffaces\u002Fpg\u002Fsite\u002FIntegrationGuides.jsf`\n- SBP PSO\u002FPSP: `https:\u002F\u002Fwww.sbp.org.pk\u002FPS\u002FPSOSP.htm`\n- SBP Raast P2M\u002FP2P: `https:\u002F\u002Fwww.sbp.org.pk\u002Fdfs\u002FRaast-P2M.html`\n\n## Limitations\n- Use this skill only when the task clearly matches the scope described above.\n- Do not treat the output as a substitute for environment-specific validation, testing, or expert review.\n- Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.\n","","imported","https:\u002F\u002Fgithub.com\u002Fsickn33\u002Fantigravity-awesome-skills","user_system_seed","SkillOPIC",true,92,512,"2026-05-16 13:33:20",{"id":8,"name":21,"slug":22,"icon":23,"description":24,"sort":25,"createdAt":26},"其他","other","mdi-page-next-outline","其他类型Skill",5,"2026-05-16 12:53:40",{"id":7,"name":28,"slug":29,"icon":30,"description":31,"moduleId":8,"sort":32,"skillCount":33,"createdAt":26},"职场发展","career","mdi-briefcase-outline","面试准备、简历优化、职业规划",4,575,[35],{"id":36,"skillId":4,"version":37,"fileName":38,"fileSize":39,"filePath":40,"fileHash":41,"manifest":42,"createdAt":19},"4979c1b9-b932-4168-b6eb-fdcba0e2fdd5","1.0.0","pakistan-payments-stack.zip",3781,"uploads\u002Fskills\u002F674266d5-df11-4153-92bd-0d186003c015\u002Fpakistan-payments-stack.zip","9df737df967dbcc76f5fcb38630d761f84c3ab8262cf6f1d05d35b236b34d98b","[{\"path\":\"SKILL.md\",\"isDirectory\":false,\"size\":8077}]",{"code":44,"message":45,"data":46},200,"success",{"items":47,"stats":48,"page":51},[],{"averageRating":49,"totalRatings":49,"ratingCounts":50},0,[49,49,49,49,49],{"limit":52,"offset":49,"hasMore":53,"nextOffset":52,"ratedOnly":16},15,false]
