Retrieves a paginated list of all beneficiaries associated with your integrator account. Beneficiaries are the individuals or businesses that can send or receive funds through your platform. Results can be filtered by status (active, inactive, pending verification), type (individual, business), creation date range, or search by name/email. Each result includes beneficiary ID, name, type, status, KYC/KYB verification state, and creation date. Use this for beneficiary management interfaces or to search for specific users.
