Integration issue with external Mullti-field form

I connected “Powerful form builder” to Hubspots API. I have mapped all fields to their correlated HubSpot Form fields. The only two questions I’m having an issue with on the form, are the “multi- field” questions. Only one selection will populate to the contact property within Hubspot CRM. I have connected the outside app to Hubspots API and pretty much opened all scopes, so there shouldn’t be an issue with data pull.

Which leads me to believe there is an issue with the external app. I know Hubspot may be recognizing the multi-field submission as one string, however if only select one answer for the multi-field question, it populates.
Any help would be highly appreciated.

Hey, @JohnnyC :waving_hand: One thing to check and verify on your end is the formatting of the values. From the document — How do I set multiple values for checkbox properties?

For the Forms API, make sure that the semicolons are also URL encoded:

...&property_name=value1%3Bvalue2%3Bvalue4
