Fix · Payments

Test cards or test numbers do not work on the live gateway

Not checked against the vendor's current screens

What you may see

I try the test card on the live site and it is declined

Most likely cause

Test cards only work in the test mode; the live mode talks to real banks.

Check first (about two minutes)

Check which mode the site is in.

Prompt language

You are a very careful senior engineer who knows online payments (including payment gateways used in Kuwait) and explains them to people who are not developers. I am not a developer, so explain every step in plain words and tell me exactly which button, menu or command you mean. If you are not sure about something, say so; do not guess.

Menu and button names change over time. If you cannot find a button or page I mention, say so and tell me what to look for instead of guessing.

THE PROBLEM
Test cards or test numbers do not work on the live gateway

THE EXACT ERROR OR WHAT I SEE

WHAT I DID BEFORE IT HAPPENED
[write in a few words what you did before it happened]

MOST LIKELY CAUSE
Test cards only work in the test mode; the live mode talks to real banks.

DO THESE STEPS, IN THIS ORDER
1. Explain how to test in test mode first and how to test live safely with one small real payment of my own followed by a refund.
2. Confirm the mode shown in admin matches the keys in use.
Stop and tell me if what you see does not match a step. Do not skip ahead.

CHECK THAT IT WORKED
- The test works in test mode, and live payments are real and refunded when I test.
Tell me exactly what I should see on the screen when it works.

DO NOT CHANGE
- Do not use other people's cards.
- Anything I did not ask about: the design, the text, other pages, other settings or the data.
- Do not delete files, data or branches, do not reset or force-push, and do not rewrite history, unless you first show me exactly what would be lost and I say yes.
- Do not paste, print or ask me to paste a password or secret key into this chat. If one is needed, tell me which settings page of the right service to store it in.

WHEN YOU FINISH
Explain in simple words what you changed (file by file or setting by setting), why you changed it, and how I can undo it.

Paste it into Claude, ChatGPT, Gemini or Cursor, then follow what it says.

After you tried it, did it work?

Steps

Do not do this

Do not leave test mode on after launch.

Fix it Test keys versus live keys (nothing works after going live)
