Quickstart

Start with a synthetic payment problem.

PaymentKits is most useful when you can describe the exact input, expected result, and whether a tool should ever see the data.

  1. Pick a small, local task

    For example: validate a test IBAN, decode an EMV TLV fixture, or compare two webhook JSON samples.

  2. Use only test or synthetic values

    Do not paste production payloads, private keys, card data, CVV values, live tokens or real bank-account details.

  3. Capture the finding as a test

    Once the expected output is clear, add a sanitized fixture to your repository so the issue cannot return unnoticed.
