Development

Test the whole flow before real money

Build and validate your integration with test keys — without a cent moving.

Test mode lets you build and exercise the entire payment journey with your zynd_test_* test keys before going live. No real money moves: you code, you break things, you retry with full peace of mind. There's no separate host or URL to manage — it's the same API, you simply switch by the key you use.

What you gain

The full flow, zero real money

Create payments, trigger events, receive your webhooks, handle edge cases — end to end. Because no real money moves, you can test the scenarios that scare you with zero financial risk.

One API, no separate host

There's no separately hosted sandbox and no different URL to configure. You use the same API: the zynd_test_* key activates test mode, the live key switches to production. Your code doesn't change when you go live.

Go to production with confidence

Once your integration holds with test keys, you swap in your live keys and you're off. What you validated in test is exactly what runs in production — no nasty surprises at launch.

How it works

Grab your test keys

Generate your zynd_test_* keys from your dashboard to enable test mode.

Build and validate

Run the whole journey — payments, webhooks, edge cases — on the same API, with no real money moving.

Switch to live

Swap in your live keys when you're ready: same integration, now in production.

Who it’s for

For any developer integrating ZyndPay who wants to test calmly before touching real money. Useful from the first line of code and at every change to your integration.
