We have a few contact properties that have been automatically created by HubSpot under the "Collected Form Fields" group. The problem is, these properties are set to read-only and we'd like to update them for some existing contacts as well as to create new contacts with proper values for them.
From reading around the forums, it seems that this is not doable either via the website or the API, and that only a HubSpot internal process can do so. Is this correct? I have also tried to submit a POST request to update one of these properties using its internal name and got 400 error.
If the above is correct, is our best option to create a new group with appropriate properties and to populate them instead? My only hesitation to this is that we'd end up having two separate (but duplicate) properties for each field. Wondering what the best practice for this situation would be. Any suggestions would be appreciated.
