Exploring the API

Explore the Visma Net’s APIs using the documentations.

Visma Net’s APIs span several independent services, each documented separately. The core service, Visma Net ERP API (the monolith), covers most of the ERP, including customers, suppliers, invoices, inventory, and the general ledger. SalesOrder and JournalTransactions are separate services alongside it, while DataMart provides access to Visma Net data through a GraphQL API.
