Create your account and get your first test key

A test key lets you try every product with simulated results, free and with no limit. Real money and real checks only start when you go live.

1. Go to Create account and sign up with your email address or your Google account.
2. Open the email we send you and tap the link to confirm your address. Check your spam folder if it does not arrive within a few minutes.
3. In your dashboard open Developers, then API Keys.
4. Press Create key. Leave 'Live key' unticked, so you get a test key that starts with io_test_.
5. Copy the key straight away. For safety we show it only once. If you lose it, create another and delete the old one.
6. Make your first call (see 'Your first API call' in this Help Center).

Nothing you do with a test key is billed, and nothing is sent to a bank, a network or any other company. Every reply says it is a test.
