We have been using custom attributes for almost 7 years via the Javascript API without issue. We have a custom attribute with the key Company Name, note the case and space.

In our javascript code we simply do this:

'Company Name': "#{current_professional.company_name}", 

and have no problems, however, when we try to use this gem and do this:

 contact = $intercom.contacts.create( email: self.account.email, name: self.full_name, phone: self.phone, role: 'lead', custom_attributes: { 'Company Name' => self.company_name } ) 

The Company Name attribute in custom attributes, it does not record the data for Company Name (its blank, everything else is fine). Every example provided shows a key in lower case with underscores, but there is no documentation that says this is required and it works perfectly fine with the javascript code.

What are we missing?
