I have integrated with Square Terminal API and need to display the contents of a receipt_url within an iframe but it’s not allowing me . I am getting the following error when I inspect under chrome.
Is there a particular attribute of an iframe that I need to set so it will display ?
I was trying to display within an iFrame control within the popup modal dialog , setting the URL of the iframe to the receipt_url. MAybe I ned to use some other control or widget within the modal dialog??
