You'll want to create a custom setting in Salesforce to store API keys, portal IDs and product__c mappings.

The settings should be named SendToHubSpot (SendToHubSpot__c) and have the following fields:
API Key 1 (API_Key_1__c), text(50)
API Key 2 (API_Key_2__c), text(50)
Portal ID 1 (Portal_ID_1__c), text(10)
Portal ID 2 (Portal_ID_2__c), text(10)
Portal 1 Product Values (Portal_1_Product_Values__c), text(255)
Portal 2 Product Values (Portal_2_Product_Values__c), text(255)
