  Hello Team,
  
  I want to develop a WordPress plugin that uses an iframe to load content from an external site. I have a few questions:

  1. Are there any limits on the type of content that can be displayed inside an iframe?
  2. Is it allowed to handle workflows like checkout or payments inside an iframe?
  3. Are there any restrictions on billing, payments, or monetization, including whether transactions must use WordPress’s native billing system even when an iframe is used?

  @staartmees Thank you for your reply. I understand the security concerns you mentioned. I’d like to confirm whether WordPress permits the use of an iframe that contains a checkout or payment page.
