I've searched here, the Products Docs, the Launchpoint PDF http://launchpoint.marketo.com/assets/Uploads/Twitter-Card-Integration2.pdf and in the wider wilds of the internet but to no availe. I keep ended up being pointed to the Launchpoint PDF which contains dead links internally to docs.marketo.com with the exact detail I probably require.
I've got a form set up in Marketo and have the hidden fields set up. I have my "index.php/leadCapture/save" with my instance address in front of it for the data but keep getting a HTTP method post error each time I try to save/test it.
Anyone who can help will get me a big thumbs up. I'm just frustrated with the lack of detail everywhere I look and then someone points me to a PDF with broken links
I have had this problem as well. I believe I re-added the fields in Twitter and tried again and it worked. I think this is a bug in Twitter.
Do I need a webhook to make my "shadow" form in Marketo pick up the leads from this? I have the same documentation and Marketo support will not help and Twitter support hasn't gotten back to me!
A webhook is outbound from Mkto, so no. The intent is for the card to cross-post to Mkto.
Happy to help you test it... it would refresh my memory as it's been awhile. I think you have my email.
Christina and I worked together to find and work around the problem.
The cause is Marketo's default SSL cert not meeting Twitter's standard for back-end integration (whether those standards are reasonable is debatable; they are not fully documented, that's for sure). By routing through another server with valid SSL, we were able to integrate Twitter Cards. I plan to blog about it, like I do everything else....
