Testing in sandbox

The sandbox is a full copy of IntaSend that moves no real money. Sign up there, copy your _test_ keys from Settings → API Keys, and use them exactly as you would live keys. See Getting started for how keys pick the environment.

When you're ready to go live, sign up on payment.intasend.com and swap in your _live_ keys. Nothing else in your integration changes.

Test cards​

Use any future expiry date and any 3-digit CVC.
