Preview & Production

There are two environments for your web funnel:

• Preview. In preview build you can test the whole flow including payments without incurring a real charge. Specify sandbox products for the Preview environment in the checkout settings. All web funnels use the same domain in the Preview - https://preview.fnlfx.com/
  Preview builds are triggered upon clicking the ‘Prevew’ button
• Production. The production version of a funnel with real payments. Specify production products for the Production environment in the checkout settings. A web funnel will be set up with a subdomain that you specify in the project settings .fnlfx.com
  Release builds are triggered upon clicking the ‘Publish’ button
