Use querystring in Change Data Value flow step

The query string is not natively available as a token.

You can use this method (with the limitations noted) to pass the query string as part of the {{trigger.web page}} token. But this still isn't parsing the query string (i.e. you will not see the utm_content value alone).

For parsing on the server side, you need a webhook -- this is something we do a lot, like when an outside agency sets up rather opaque UTM params and we want to translate them into friendly names back on the lead.

But parsing is only necessary when you want to post data without a form. As you are using a form, I'm not convinced you can't do this using standard hidden UTM fields and spare yourself the complexity of server-side parsing. Why not add the field to the form, but just empty the value (using Forms JS) if it isn't "Promo1" (or any other interesting value):

MktoForms2.whenReady(function(form){
  // list your interesting values for certain fields 
  // non-interesting values will be removed 
  var interestingValues = { 
      "utm_content" : ["Promo1","another value"] 
  }; 
  /* --- NO NEED TO EDIT BELOW THIS LINE! --- */ 
  
  form.onSubmit(function(form){ 
    var currentValues = form.getValues(); 
  
    Object
    .keys(interestingValues)
    .filter(function(field){ 
      return !interestingValues[field].some(function(value){ 
        return value === currentValues[field]; 
      }); 
    })
    .forEach(function(field){
       var mktoFormData = {}; 
       mktoFormData[field] = ""; 
       form.setValues(mktoFormData); 
     });
  }); 
});

Hi @@Natali,

In the flow step tab can you not just add a wait step of a few minutes at the very start to give the system time to update the utm_content field and then do a check of that field.

Change data value

if UTM_Content = promo1

Thanks,

Gerard

Thanks for the help. As I mentioned, I can't put the field as a hidden field on the form as I only want this to be populated for nett new leads, and not everyone who submits the form. Gerard Donnelly​ - UTM Content isn't a field in Marketo, so you cannot use it in the flow step as suggested.

My biggest issue is the web page activity doesn't include anything past the base URL within the URL name, and instead passes it to the query string section, which is only a constraint on the filter/trigger and not available in a flow step. It looks like the workaround to pass the query string as part of the web page trigger might work, as essentially what I'm trying to do is have a flow step that says "If web page contains utm_content=Promo1, then update Field with Promo1. I'll give it a go and see what happens.

Thanks again!
