If you need to try out our payment functionality in a test environment first, sign up for a demo merchant account. This is an exact replica of production. No actual payments can be made within this environment, but you can use our test cards to make demo payments of 30¢/30p or more.

If already signed up for a demo account, visit sign up and click on the Sign in link. Log in using the username and password you already set up. Username is your mobile number but without the opening zero.
