@Hueseyin Not sure if I understood well. I think you are confusing properties with custom fields. The property ‘property’ defines which fields will be returned after the operation is executed. I guess it’s not the best name, but it’s how Hubspot calls it. I think I sent a commit that updates that name to fields.
The fields description says the following:
It is used to include specific company properties in the results.
By default, the results will only include company ID and will not include the values for any properties for your companys.
Including this parameter will include the data for the specified property in the results.
To solve this, you have to create a custom field on Hubspot like this Manage your properties, but sadly on the n8n side, there is no way yet to set custom fields. I will add this to my TODO list.
What you can do in the meantime is change the name of a property you do not use, for example, company_size to something like ‘interest_group’ and set in n8n as company_size. So within Hubspot, you will see the right label ‘interest_group’ with he value you set in n8n as company_size.
Hope that helps, if not simple get back to me.
