Trouble with date field using API


#1

I’m trying to submit a date using the form api. This is being sent as a millisecond timestamp but it’s being rejected. Can you please take a look?

The form url is
https://forms.hubspot.com/uploads/form/v2/3446859/9132430f-d1f2-487d-8cf1-0941e501b5d3

And fields are
full_name=&company=Studio+Republic&companyhq=&email=chris4%40studiorepublic.com&phone=%2B448452263205&home_state_province=Hampshire&home_country=United+Kingdom&host_country=United+Kingdom&date_arrived_in_host_country=1427997766000&est_length_of_stay_in_host_country=aaa&type_of_work_visa=bb&how_did_you_hear_about_gtn_=cv&additional_info=dd&hs_context=%7B%22hutk%22%3A%2285e3fc1c6f6741195003c80cd6a86acb%22%2C%22ipAddress%22%3A%2282.24.85.71%22%2C%22pageUrl%22%3A%22https%3A%5C%2F%5C%2Fc0149.paas1.lon.modxcloud.com%5C%2F%22%2C%22pageName%22%3A%22Home%22%7D
