Test Payment

It is possible to perform a test payment via Sisow as a merchant. To do this, log in to Sisow. The Dashboard in Sisow is only in Dutch. In the dashboard, go to Profiel / Geavanceerd and activate the option 'Testen met behulp van simulator (toestaan)'.

Go to Content / Pages in the back office. Select 'preview' via the arrow behind the page to go to your webshop. You can then place a test order.


Each payment method - such as iDEAL or Visa - must be requested separately from Sisow. Please note this if you decide to offer more than one payment method. Always activate payment methods first at Sisow and only then in the management environment of your shop.
