Explanation of each setting

New checkout

Enables Zru's checkout v2. This checkout requires style templates set up in Settings ▶︎ Themes. You can learn more about Themes in this guide.

Redirect to client using an iframe from the parent

When enabled, if the payment screen is shown inside an iframe and has to send the user to the return_url or cancel_url, the redirect is performed from the top of the window (outside the iframe).

When disabled, the redirect happens inside the iframe itself.

Cancel transaction / authorization / subscription in case of failure

When enabled, if a user fails to confirm an operation, the transaction, authorization or subscription is cancelled automatically.

Expiration notification

When enabled, a notification is sent when a transaction, authorization or subscription expires.

When disabled, the operation expires but no notice is sent.

Asynchronous notifications

When enabled, once an operation is confirmed the notification is sent without waiting for your server's response: the user is redirected to the return_url straight away.

When disabled, the system waits for your server's response before redirecting the user.

Notification retries

If a notification is sent and no OK is received, the system tries again after a while. This numeric field sets the maximum number of retries.

🧐 The default value is 3. You can change it to suit your needs.
