Connect Your Shop to EPaySe With an AI Coding Assistant

Yes, an AI coding assistant such as Claude Code can write most of the code that connects your shop to EPaySe. You describe what your shop needs, it writes the code, and you review it and test it in a sandbox. The assistant does the typing. You stay responsible for checking the result before any real customer pays.

• What it does: writes the code that creates a payment and handles the answer.
• What you do: review the code and test it with fake payments.
• What helps: EPaySe publishes a written guide made for coding assistants.

What is an AI coding assistant?

It is a tool you talk to in plain language, and it writes or changes code in your project. Claude Code is one example. Others exist, such as Cursor and Windsurf. You do not need to be a developer to see what it produces, but someone who can read code should review it before you accept a payment.

Why is payment code hard for an assistant?

Payment code has strict rules. A small mistake can make every payment fail, or worse, work in testing and break with real money. Typical mistakes are sending the amount in the wrong unit, or building the security check in the wrong way. An assistant working from memory can get these wrong, because every gateway has its own rules.

How does EPaySe help?

EPaySe publishes a written integration guide made for coding assistants. It explains how to talk to EPaySe, how to check the confirmation messages EPaySe sends back, how to handle refunds, and which mistakes to avoid. It also includes example code in PHP, Node.js, Python and Go. When the assistant reads this guide, it follows EPaySe's real rules instead of guessing. The next article, give Claude Code the EPaySe guide, shows how to set it up.

What should you still check yourself?

• The amount. Make sure the code sends dollars with decimals, such as 10.50, and not cents.
• The secret key. Make sure it is stored in your server settings, never in the code or in a chat. See keep your EPaySe secret key away from your AI assistant.
• The paid status. Make sure an order is marked paid only after EPaySe confirms it. See mark orders paid only after EPaySe confirms.
• Testing. Run the sandbox tests before going live. See test your EPaySe integration in the sandbox.

What does a good first request look like?

Keep it small and specific. For example: "Add EPaySe checkout to my order page. Use the sandbox. Create the payment, send the customer to the checkout page, and mark the order paid only after EPaySe confirms it." A narrow request is easier to review than a big one.

EPaySe is an early-stage payment gateway, still in development, so treat everything as a sandbox exercise first. Read the documentation for details.

Key takeaways

• An AI coding assistant can write most of the integration code.
• You review the code and test it in the sandbox before any real payment.
• EPaySe's written guide helps the assistant follow the right rules.
• This is general education, not legal or financial advice.

You do not need to write code, but someone who can read it should review the code before you accept real payments.

Is it safe to let an AI assistant write payment code?

It can be, if you give it the right guide, keep secret keys away from it, and review and test everything before going live.

Which AI coding tools can use EPaySe's guide?

The guide is made for Claude Code, and it is plain Markdown, so other tools such as Cursor or Windsurf can use it through their own context files.

Does EPaySe write the code for me?

No. EPaySe provides the documentation and a guide for assistants. The assistant writes the code and you check it.
