Agent Credentials
Agents sometimes need a secret to do their work — for example, an access token for an external service or a key for a third-party API. Agent credentials are how a worker asks a person for that secret, receives it in encrypted form, uses it for a bounded period, and has it withdrawn afterwards.
Customers
A Customer is the central entity in the FAR module. It represents a financial relationship with a party — the entity you invoice, collect payment from, and manage receivables for. Every customer references a party in the PRM (Party Relationship Management) module, linking the accounts-receivable record to the broader party identity.
