iFrame embedded Landing page - How can I hand over the follow-up parameters from LP to iFrame

[daniela_arndt]

We have setup a SAP Marketing Landing page with a follow-up page. This landing page is inserted into an iFrame.
We now have the problem that the follow-up page can't be opend in the iFrame. In my opinion the information of the follow-up page should be handed over from the landing page to the iFrame. Unfortunatly this case is not in the setup documentation and we got now stuck. I hope somebody already have managed this successfully and could help us.

As an alternative it would be also ok to open the follow-up page in new tab. But this possibility is not foreseen in the Content studio. I just can enter an URL address. But maybe there could be also a trick.

We have an on-prem installation.

Hi Daniela,

If you use a follow-up page for your landing page which is embedded in an iFrame, this will only let the iFrame navigate to the follow-up page. Your surrounding website will stay but only the iFrame will display the follow-up page. Note: If the server of your follow-up page sets content security policy headers, the browser might deny the display of the follow-up page in the iFrame (you can check your browser console for an appropriate error message). In general, this works as designed.

Instead of letting the iFrame navigate, the surrounding website would need to navigate to the follow-up page. This could be implemented by using the postMessage API (see https://developer.mozilla.org/en-US/docs/Web/API/Window/postMessage). Using this API, the iFrame could inform the surrounding website to perform navigation. The surrounding website would listen to such messages and react accordingly.

Currently, the standard landing page JavaScript does not make use of the postMessage API. Instead, you could opt to change the standard JavaScript to send the required messages instead of navigating to the follow-up page. Please note that this would mean that you need to change the standard JavaScript every time you update it after an upgrade of SAP Marketing Cloud.

To request this feature as part of the standard, please open an idea in the SAP Customer Influence tool: https://influence.sap.com/sap/ino/#/campaign/38

Kind regards
Steffen

Hi daniela.arndt,

How did you insert the Landing Page in an iFrame on your website?

When I try that, I get the following error: https://answers.sap.com/questions/13193032/landing-page-in-iframe.html

Thanks,
