Develop an Endpoint in the Holded API that returns a “key/value” with all Holded Countries.

This is a requirement that we have detected to limit the user to only the countries that you have in Holded.

What this country call would do would be to upload all the Holded countries to a custom property of the integration in HubSpot and, in this way, the user could only select, as a drop-down, the countries loaded via API.
