    description: >-
      CSG Forte provides full-stack REST APIs for payment processing within a
      PCI-compliant architecture. The API enables merchants and partners to
      create and update credit card, echeck, and scheduled transactions,
      securely manage customer and payment data, and query settlement
      information. Authentication uses HTTP Basic with organization ID,
      location ID, and API key.
