Ability to pre-fill form when linked to from a Marketo landing page?

ailsadempsey · ‎09-21-2021

Is there a way to have a Marketo form pre-fill if it's linked to from a Marketo landing page, that would be arrived at from a Marketo email (and so with mkt_tok)?

We are looking at developing a preference centre that houses a couple of email subscription options. We were also looking to have a separate unsubscribe page/form that would be a global unsubscribe, so the idea was to have copy on the unsubscribe page highlighting this and a link to manage preferences instead if preferred. However I'm not aware of a way to have the preference centre form pre-fill for a lead if they navigate there from the unsubscribe page (accessed from Marketo email) - only if they access the preference centre directly from the email. Is there a way to achieve this? Or is the only option to combine the two into one?

I tried to add a link to the landing page but I only had the option to mark it as track link, not add mkt_tok (as you do in the email editor).

Right, there’s no feature like that — understandably, as it would break the security approach of removing the mkt_tok on load.

What you can do is

add a special class only to those links you want to pass the mkt_tok
only add the mkt_tok when the link is clicked, not before, so if the link is copied it’s still secure

Use this HTML:

<a class="mktReTok" href="https://pages.example.com/unsubscribe">This link will have the original mkt_tok added</a>

And this JS:

document.addEventListener("DOMContentLoaded",function(){
  const arrayify = getSelection.call.bind([].slice);
  
  arrayify(document.querySelectorAll("a.mktReTok"))
  .forEach(function(link){
     link.addEventListener("click",function(){
       this.search += ( this.search ? "&" : "" ) + "mkt_tok=" + window.__mktTokVal;
     });
  });
});

It’s easy to make this happen if they’re both Marketo LPs. Is that the case?

Yep, both Marketo landing pages. I tried to add a link to the landing page but I only had the option to mark it as track link, not add mkt_tok (as you do in the email editor).

Hi,

where do you out that code?

SanfordWhiteman · ‎06-02-2022

You can put it in the <head> or anywhere else, doesn’t matter as it waits for the page to be ready.

Thanks so much!

Hello,

I don't know a direct way of doing this, but you can do it with the 2 following steps

~~1. Create a trigger campaign for the e-mails. If the person clicks the unsubscribe link you update the preferences field value.~~

2. In the forms you enable the pre-fill of the preferences field

You should never update data based only on a Clicked Email, as you'll be responding to mail scanners, not just humans.

I don't understand the rest of your post... how would that accomplish Pre-Fill?

LucasMachado · ‎09-21-2021

you're right, I thought forms were still using munchkin code to pre-fill but now it is only the e-mail token. Sorry!
