How to Connect to Constant Contact Signup Page with HTML/JSP

[RandyK7454]

I'm currently working on building website templates, and one of the issues I have is trying to embed the Contact Contact signup form, aka https://go.constantcontact.com/signup.jsp. Whenever I try to do so using <iframe> or <embed>, there would always be an error on my website page where "go.constantcontact.com refused to connect." (same goes for the Constant Contact home page)

(The line of code that results in this problem.)

<iframe src="https://go.constantcontact.com/signup.jsp"></iframe>

However, it would connect with Constant Contact's newsletter signup:
<iframe width="420" height="345" src="https://lp.constantcontactpages.com/su/7ntQ0lw">

(likely because the link has a different address)

I searched up threads in Developer Support, but only found questions related to connecting to signup forms made with this website, but not the ones from the website. I was wondering why embedding seems to be disabled for specifically Constant Contact, and if there is a way to do so, then I'd love to know. Is it for security or copyright reasons that embedding is disabled, or is there's a way to connect that I am unaware of?

Thank you for the help.

Hello Randy,

Thank you for reaching out to Constant Contact API Developer Support, my name is Courtney. My team is here to assist outside software developers with questions about building into Constant Contact's API.

While your question does not directly relate to Constant Contact’s API or Developer Portal, I did some additional research to ensure we could get you the best answer to your inquiry.

Some web pages may not display within iFrames due to security headers set within the page. These are used by the server to tell the browser whether or not the URL being requested can be used inside of an iFrame. In this case, sharing that page is most likely restricted due to our Terms of Use.
