Currently a customer of mine who uses Hubspot sets their sfdcCampaignId via the embed code at the time of form creation.
What they want to accomplish is being able to pass this id in via a URL to dynamically populate this ID on the form on page load. This way they can use this same form but have it associate with different Salesforce Campaign IDs.
I’ve been told the sfdcCampaignId is a hidden field but I’m guessing it is dynamically generated on the fly at the time of submission as I’m not able to locate it as an actual form field.
I’m trying to avoid going through the Forms API route and wondering if this is possible to do via onFormReady or onForm Submit callbacks in any way?
