  SAP Business One is an affordable, on-premise or cloud ERP solution designed
  for small and midsize businesses, covering finance and accounting, purchasing,
  inventory, sales, CRM, production, and analytics in a single integrated
  application. It exposes programmatic access through the Service Layer, a
  modern REST/OData v4 API for the SAP HANA edition, alongside the legacy DI
  API and DI Server for SQL Server deployments. Authentication uses
  session-based login that returns a B1SESSION cookie used for subsequent
  OData calls against company databases.
