ECPay Technology lance AI Skill ! Les développeurs peuvent utiliser l'IA pour intégrer les paiements, prenant en charge des outils comme Codex, Gemini, etc.

Taiwan Green World Technology releases ECPay API Skill documents on GitHub. Developers can use AI tools like ChatGPT to access payment integration knowledge, directly generate code, and troubleshoot errors, effectively lowering the barriers to system integration.

Taiwanese payment service provider Green World Technology (ECPay) recently published the ECPay API Skill on GitHub, consolidating knowledge on API integration for payment, logistics, electronic invoices, and ECTicket into Skill documents readable by AI development tools. This allows developers to directly assist in ECPay API integration within environments such as OpenAI Codex CLI, Google Gemini CLI, ChatGPT GPTs, Claude Code, Cursor, GitHub Copilot CLI, and others.

According to the ECPay GitHub documentation, the current version of ECPay API Skill is V3.2. The installation guide supports three main entry points: ChatGPT GPTs uses SKILL_OPENAI.md as the entry file; OpenAI Codex CLI uses AGENTS.md; Google Gemini CLI uses GEMINI.md.

Developers only need to add the Skill to their project to enable AI tools to access the Green World API knowledge base, assisting in code generation, error troubleshooting, parameter verification, and switching between test and production environments.

From "Reading Documentation" to "Asking AI": Lowering the Barrier to ECPay API Integration

In the past, developers integrating payment services often had to repeatedly consult API documentation, handling CheckMacValue validation, payment parameters, Webhook, error codes, invoice issuance, logistics integration, and other details. While these processes are familiar to experienced payment engineers, teams new to integration might still encounter issues with environment setup, field formats, encryption signatures, or test MerchantID.

The core concept of ECPay API Skill is to convert these documents into a knowledge base that AI can understand and reference. Official documents even provide validation examples, allowing developers to directly ask Codex or Gemini: "What is the test MerchantID for Green World AIO payment?" The expected answer would be 3002607.

Support for Payment, Logistics, Electronic Invoices, and ECTicket

ECPay API Skill covers a comprehensive range of topics. The core Knowledge Files listed in the ChatGPT GPTs build guide include AIO payment, on-site payment 2.0, backend authorization/number retrieval, B2C electronic invoices, CheckMacValue, AES encryption, error codes, Webhook, HTTP protocols, and multilingual integration.

Additional documents include beginner guides, B2B invoices, domestic logistics, comprehensive logistics, ECTicket, and cross-service scenarios. The official recommendation for GPT creation is to name it "ECPay Green World Technology Integration Assistant," positioned as "Green World Technology's official API integration consultant," supporting payment, logistics, electronic invoices, and ECTicket, and available in 12 languages.

This also positions ECPay API Skill not just as "document organization," but as an AI API advisor that developers can build, deploy, and update themselves.

Can be integrated into Codex, Gemini, or self-built ChatGPT GPTs

For Codex CLI and Gemini CLI, the official provides three methods: project-level installation, global installation, and Git Submodule. The project-level installation is recommended, where developers clone the GitHub repo into the project directory as .ecpay-skill, then reference the entry files in Codex's AGENTS.md or Gemini's GEMINI.md.

To create ChatGPT GPTs, SKILL_OPENAI.md, SKILL.md, and multiple guides need to be uploaded to Knowledge Files. The documentation emphasizes that SKILL_OPENAI.md is a simplified entry point for GPT, and because it exceeds the token limit in the Instructions field, it is recommended to upload it directly to Knowledge. If there is a conflict with the full decision tree SKILL.md, SKILL_OPENAI.md takes precedence.

ECPay also recommends enabling Web Search for GPTs to facilitate real-time access to the latest official specifications on developers.ecpay.com.tw.
