We're trying to import information from Salesforce into our Grails3 system and don't really need to authenticate every user since we can control user access at our system login. Can we use something a bit more permanent to send API requests to our my.salesforce.com instance at a system level without having to prompt our already locally logged-in authorized users to authenticate with SF every time we want to import another record from SF to our system?
