Before you can use Realex’s Realauth Redirect, you must first provide Realex with the URL of your callback page. This should be:
(this is URL-mapped to the Callback.aspx file by Kartris)
The response URL is to be mailed to firstname.lastname@example.org. You can also have an HTML template uploaded to the Realex Payment servers so that the redirection should resemble the rest of the shopping experience (or else it will use Realex’s default template). You can send your template to them via same email address. For further info, check the Realex developer's guide.
In case Realauth is unable to contact your callback page, you can set a static success/failure message. This can be done at Realex's administration web site (Realex will have supplied you with access details).
Ensure your page has the following code pasted near the bottom, before the closing 'body' tag.
Copy this code and place it where you want the help icon to appear in your page.
Your help link will appear as the icon below. Click it to verify how the help content will look.
Place a QR code on your product or machinery to let a user easily retrieve the user guide documentation for it.
