Fake Transaction ID Generator
Payment flows are tedious to test without realistic transaction IDs. Real providers like Stripe issue IDs such as txn_3Qk7... or pi_abc... — a short prefix identifying the object type, an underscore, then a long alphanumeric string. If your fixtures use generic placeholder strings, your UI and log code may never see the format edge cases that matter. This tool generates fake transaction IDs using the same pattern: a random prefix from txn, pay, ch, pi, or ref, followed by an underscore and 24 random lowercase alphanumeric characters. Choose how many you need, up to 20, and copy them into fixture files, mock API responses, or seed scripts. Because each ID is entirely random and references nothing, they are safe to commit to a test repo or paste into a code review. When you move to integration testing, your real payment provider supplies the genuine IDs.

FAQ
are these real transaction IDs
No — they are fictional identifiers that mimic the format of real payment systems. They reference no actual transactions and carry no payment data. Use them only in test and development environments, never as real references.
what prefixes does this tool use
The generator picks randomly from txn, pay, ch, pi, and ref — prefixes that mirror common payment-provider conventions. Each prefix is followed by an underscore and 24 random lowercase alphanumeric characters, matching the general shape of IDs issued by providers like Stripe.
can I use these in production
No — they are for testing only. In production, transaction IDs come from your real payment provider. Using fake IDs in production would break reconciliation and could mislead users; keep them confined to test fixtures and mocks.
