Collecting IP address once form is completed

[Anonymous]

Hi,

Is there any way to collect a recipient's IP address once they have completed a Marketo form?

Thanks,
Nicole

Marketo silently collects the IP address when a lead fills out a form.

That information is accessible through the Activity Log.

Assuming the IP is relevant for GeoLocation or user-defined activities, you can either use SOAP API to retrieve that information of add a JavaScript to save the IP and GeoLocation to custom fields.

The SOAP API call would be getLead or getMultipleLeads

http://developers.marketo.com/documentation/soap/getlead/

http://developers.marketo.com/documentation/soap/getmultipleleads/

getLeadActivity is also a good fit

http://developers.marketo.com/documentation/soap/getleadactivity/

You can then use syncLead or syncMultipleLeads to find the IP and location to custom fields

http://developers.marketo.com/documentation/soap/synclead/

http://developers.marketo.com/documentation/soap/syncmultipleleads/

A small JavaScript allows to read and save that information in one go when the form is saved:

function myIP() {

    if (window.XMLHttpRequest) xmlhttp = new XMLHttpRequest();

    else xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");

    xmlhttp.open("GET","http://api.hostip.info/get_html.php",false);

    xmlhttp.send();

    hostipInfo = xmlhttp.responseText.split("\n");

    for (i=0; hostipInfo.length >= i; i++) {

        ipAddress = hostipInfo[i].split(":");

        if ( ipAddress[0] == "IP" ) return ipAddress[1];

    }

    return false;

}

Good approach but the JS example won't work in every browser, plus the ActiveX requirement will fail on restricted machines. But, it shows a common way of getting IP from external provider and using it in a form.

Georgi, I totally agree with your reamrks. I am originally Unix user, happy to ambrace Linux and Mac OS X.  

The example is agnostic

$(document).ready(function () {

  $.get('http://jsonip.com', function (res) {

  // assign the IP to a hidden field using res.ip

  });

});

I need to save IP Address to a field in Salesforce for CASL compliance. How can we do this? I dont know Javascript or know where to put this and dont have developer resource or budget to hire Marketo.

We have the same need for a legal requirement in Germany. Where would I put the JS code and how would that populate the hidden field?

Thanks!

You would place the code either in a snippet, html, or rich text on the landing page. Place <script type="text/javascript"> at the start and </script> at the end so that it is hidden, Like: 

<script type="text/javascript">
MktoForms2.whenReady(function(form){
form.onSuccess(function(values, followUpUrl){
fetch('https://api.ipify.org?format=json')
.then(response => response.json())
.then(data => {
var ipAddress = data.ip;
// Update the custom field with the IP address
form.addHiddenFields({
"{{YOUR FIELD NAME}}": ipAddress
});
})
.catch(error => console.error('Error fetching IP:', error));
});
});
</script>

In your form add the field {{YOUR FIELD NAME}} to the bottom of your form, field type=hidden. 

Save and approve form, approve LP, and test by filling out form.

1. This post is 10 years old. Please open a new thread if you have a similar question.
2. The code you posted will not work at all. It’s clearly not tested; at no time are you saving the IP address to Marketo.
3. People don’t just post from a single IP address, so even in the case where you do save the IP addresses to Marketo, it needs to support multiple IPs per person.
4. The Client IP Address is automatically a property of every Filled Out Form activity.
