Nexa API: connecting external systems

The Nexa API was announced as an interface for connecting external systems. Its focus was data exchange between the ERP and other applications.
The announcement directed questions about individual connections to the sales team. Scope, permissions and required data flows need to be agreed for each project; an API does not mean an integration is configured automatically.
