SAP Business One API: what you can do and how to use it with AI agents
SAP Business One exposes its data and documents through the Service Layer, a REST API based on OData, in addition to the older DI API. Mid-size companies and SAP partners who connect e-commerce, CRM and logistics to the ERP use it. Access is through a Business One user and a session opened on the Service Layer of the company's installation.

Questions about the SAP Business One API
Is the SAP Business One API free?
The Service Layer is part of SAP Business One. The use of users and licenses follows the contract with your SAP partner.
Do I need to code to use the SAP Business One API with iTeam?
Not necessarily. The deployment team sets it up with your SAP partner, and iTeam uses the Service Layer documentation.
Service Layer or DI API?
The Service Layer is REST and better suited to modern integrations. The DI API is older and runs locally.
