Users see this error “API call error:Bad Request” whenever they submit a form, however hubspot still collects their contact information and they still land on the thank you page but it sometimes leads to the submissions not landing in our email.

Here’s what we can see in the call log for the api key:

HTTP 400 post /contactslistseg/v1/lists/1/add

@PGeorgia,

It looks like the contacts you are trying to add via the API do not meet the list criteria. Perhaps some obligatory fields are missing?

What do you exactly mean by list criteria? Bcause we didn’t set up any. Is it the filters that are set upf for the lists? Because we only have this one: "Form submission ;has filled out **Any form submission** on **Any page**"

Hello @PGeorgia,

Dynamic lists won’t let you manually add contacts, but any new or updated contacts would automatically get added to the list if they meet the criteria. Please check if the contact you were trying to add match the list criteria?

Regards,
