Form submitted successfully via API, but doesn't appear in Hubspot
I'm using the API to add contacts / update activities via form submissions.
For most forms, it works perfectly, but for a new form I created yesterday it just doesn't work. I made a log, and I'm seeing a success message from Hubspot:
{"inlineMessage":"Thanks for submitting the form."}
But I don't see the activity represented in Hubspot. New contacts aren't added and don't appear in the account. Existing contacts still appear with their last "conversion" from previous form submissions, and not this one.
