tw-payment-integrationIntegrate Taiwan payment service providers including credit card, ATM transfer, convenience store payment, and mobile wallets (LINE Pay, JKoPay).
Tw Payment Integration is an agent skill from asgard-ai-platform/skills. Integrate Taiwan payment service providers including credit card, ATM transfer, convenience store payment, and mobile wallets (LINE Pay, JKoPay). Use this skill when the user needs to accept payments online in Taiwan, choose a payment gateway, understand payment flows, or handle refunds — even if they say 'accept payments on our site', 'which payment provider in Taiwan', 'integrate credit card payments', or 'set up LINE Pay'.
Its SKILL.md is about 1.5k tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including reference files (for example `examples/sample_scenario.md`, `references/ecpay-api.md` and `references/pci-checklist.md`).
It sits in Backend & APIs, covering Payments and billing. The repository describes itself as: 301 open-source coding agent skills across 22 domains — methodology, judgment & gotchas packaged as Claude Agent Skills for the Asgard AI Platform. The licence is MIT.
Read from SKILL.md and the folder at commit 4e7f4f8. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown).
From the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Tw Payment Integration loads about 1.5k tokens when it runs, and up to ~8.1k if it reads all its reference files. Until then it costs about 113 tokens; SKILL.md has 483 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Taiwan consumers expect choice. Credit card alone misses ~40% of potential
buyers. The minimum viable payment mix for Taiwan e-commerce:
1. Credit card (信用卡)
2. ATM/bank transfer (ATM 虛擬帳號)
3. Convenience store payment (超商代碼/超商取貨付款)
Adding LINE Pay and Apple Pay captures another 10-15%.| Method | Market Share | User Profile | Settlement Time |
|---|---|---|---|
| Credit/Debit card | ~45% | All ages, higher spending | T+1 to T+7 |
| ATM virtual account | ~15% | Price-sensitive, no credit card | Instant to T+1 |
| Convenience store (超商代碼) | ~10% | Students, cash-preferred | T+1 to T+3 |
| LINE Pay | ~12% | LINE users (95% of Taiwan) | T+1 to T+7 |
| Apple Pay / Google Pay | ~5% | Mobile-first users | T+1 to T+7 |
| 超商取貨付款 (COD at store) | ~8% | Low trust, want to see product | Upon pickup + T+3 |
| JKoPay / 街口 | ~3% | Younger demographic | T+1 |
| PSP | Strengths | Pricing | Best For |
|---|---|---|---|
| 綠界 (ECPay) | Most comprehensive (credit card, ATM, CVS, 超取), largest market share | 2.75% credit card, NT$15/ATM txn | General e-commerce, startups |
| 藍新 (NewebPay) | Good API design, modern dashboard | 2.5-2.8% credit card | SaaS, subscription businesses |
| TapPay | Mobile-first, Apple Pay/Google Pay/LINE Pay integration | 2.5-2.8% credit card | Mobile apps, in-app purchases |
| PayNow | Easy setup, no monthly fee | 2.75% credit card | Low-volume, new businesses |
| Stripe | International, excellent API | 3.4% + NT$10 per txn | Cross-border, international focus |
1. Customer clicks "Pay" on your site
2. Your server creates an order → sends to PSP API
3. PSP returns a payment page URL (or token for inline)
4. Customer completes payment on PSP-hosted page
5. PSP sends callback (webhook) to your server with result
6. Your server verifies the callback signature
7. Update order status → show confirmation to customer| Concept | What It Is |
|---|---|
| MerchantID | Your account identifier with the PSP |
| HashKey / HashIV | Secret keys for signature verification |
| TradeNo | Your order ID (must be unique per transaction) |
| PaymentType | Credit, ATM, CVS, WebATM, etc. |
| Callback URL | Webhook endpoint PSP calls after payment |
| Return URL | Page to redirect customer after payment |
| CheckMacValue | HMAC signature to verify data integrity |
| Method | Refund Capability | Timing |
|---|---|---|
| Credit card | Full or partial refund via API | 1-7 business days |
| ATM | Cannot auto-refund — must wire transfer back | Manual, 3-7 days |
| CVS payment | Cannot auto-refund — must wire transfer back | Manual, 3-7 days |
| LINE Pay | Full refund via API | 1-3 business days |
| Requirement | What to Do |
|---|---|
| SSL/TLS | All payment pages must be HTTPS |
| 3D Secure | Enable 3DS 2.0 for credit card fraud reduction |
| PCI DSS | If handling raw card data, need PCI compliance. Using PSP-hosted payment page avoids this. |
| Tokenization | Store payment tokens, never raw card numbers |
| Webhook verification | Always verify CheckMacValue signature before processing callbacks |
| Idempotency | Handle duplicate callbacks gracefully (PSP may retry) |

SKILL.md names no scripts, command-line tools or credentials: Tw Payment Integration is instructions for the agent only.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.

Tw Payment Integration is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 1.5k tokens (SKILL.md is roughly 6.1k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 6.6k tokens, read only when the agent opens those files.
