Integrations — Once®

CAD Integrations

Connects drawings and engineering data

Once® integrates directly with CAD authoring tools. Check files in and out, generate PDFs automatically and keep document revisions in sync without leaving your design environment.

→ AutoCAD add-in for check-in and check-out directly from the design environment
→ Drawing automation with the Once® add-in - generate and update drawings directly from project data
→ Inventor add-in for managing BOM structures and keeping assembly data in sync with Once®
→ Automatic PDF generation on file save - no manual export step
→ Drawing revisions locked in Once® as soon as files are checked in
→ Tag, Item and document data accessible from within CAD

ERP Integrations

Engineering and procurement, always aligned

Keep your ERP and Once® in sync, without manual re-entry. BOM structures, item register and project data flow between systems so procurement always works from the same data your engineers defined.

→ Bi-directional BOM and item master synchronisation
→ Project and purchase order data exchange
→ Configurable field mapping per ERP system
→ Procurement aligned with engineering scope without manual handoff
→ Currently supports SAP, BC and Visma - additional ERP systems in progress

API & Data Exchange

Built for integration and automation

The Once® REST API gives you structured access to all your project data like tags, documents, BOMs, engineering registers and more. Build custom integrations, trigger workflows from external systems or export data for analysis, reporting and third-party tooling.

→ REST API with token-based authentication
→ Structured JSON access to tags, documents, BOMs and registers
→ Webhook support for event-driven integrations
→ Export and import for migration, reporting and data exchange
→ Enables custom integrations to third-party systems
