You will need to make sure you have added the tracking code and then are collecting the hubspotutk cookie value. Then, when sending your form data, you would add this object to the JSON:
"context": {
"hutk": ":hutk", // include this parameter and set it to the hubspotutk cookie value to enable cookie tracking on your submission
"pageUri": "www.example.com/page",
"pageName": "Example page"
}
Form submission didn't include IP Address — How to add cookie to link submissions to contacts
We are still experiencing the issue here. Can we get some help?
Additionally, we recently got a new submission with the "didn't include an IP address" message, as well as a message saying "Submission from excluded IP address".
Is the API call + cookie retaining the IP address or not? Can't tell.
