Submit data to a form (with attachment?)


I used the submit to a form API documentation and was able to post from an external site to a HubSpot form.

I’m not seeing any documentation on how to also include an attachment with the form. Is there a C# example somewhere?


@Kizmar file upload properties can only store the URL pointing to a file, they can’t store the file itself, so if you’re submitting data to a form with a file upload field, you’d need to upload the file to some other storage location, then include the URL for the file in the form data.
