CRM car with custom propery

[JCHABAUD]

Hi, 

In my CRM card, I added a custom property siret (=company register number)  in the list of properties sent from hubspot.

In the URL request sent by hubspot there are the city, the name ... but the siret parameter is missing . 

Is it possible to sent a the custom field ? 

P.S. :The siret porperty is  ok in the company :

Strange !!!
