The ERP API lets you read and manipulate data in JTL-Wawi: orders, products, customers, invoices, inventory, and more. It is available as a REST API (all versions) and, starting with v2.0, as a GraphQL API.

OpenAPI Spec

Download the spec for any supported version. Import into Postman, Insomnia, or generate a client. Each API version ships with a specific JTL-Wawi release, and a single JTL-Wawi release usually ships more than one API version. The table groups the available API versions by the JTL-Wawi version they ship with. The version selector shows the same JTL-Wawi version next to each API version.
