Viva Wallet makes trying out integrations easy with a demo (sandbox) environment which is an exact replica of production. Or you can dive straight in with a live account. Find further information below on the two options available.
The demo work environment can be used for all your development/demonstration requirements. No actual payments are made from this environment.
A successful transaction can be simulated (in the demo environment only), with the demo card number 4111111111111111 with any future expiration date and 111 for the CVV2. All other card numbers will result in a failed transaction. You can create demo accounts from here, all that is required is a mobile phone number. The minimum transaction amount is 30p.
Actual transactions are executed in the live environment. The minimum transaction amount is the same as for the demo environment.
