Missing form submissions with 204 response




I’ve been handed an old project that is an iOS App that displays forms downloaded from hubspot, captures the data entered and uploads each submission to hubspot.

We are submitting form data and receiving a 204 status code in the response.

However there are zero submissions appearing in the Form dashboard.

To the best of my knowledge we have followed the form submission guide.

Here is an example of the data being sent:


Is there any restrictions on the hubspot side (e.g. limited number of contacts) that would prevent successfully sent submissions from appearing?

Any information would be appreciated.

Let me know if you require any further information.



Hi @MrAPolk,

Can you direct message me with a link to the form (in HubSpot) that you’re submitting to? Are you unable to see the submissions if you visit the submission page of that form directly?



The submissions were found attached to the form but were not showing up in the Form dashboards submission count.

I’m assuming this is due to the submissions containing test values that didn’t link a submission to a valid contact.

Thank you for your time,
