The Voltn API: integrate your applications with a sovereign cloud
Voltn (formerly NetExplorer) provides a complete, documented REST API. Your business software can directly control your file platform: data stays in France, and data flows remain under your control.
Documented REST API
OAuth2
Why integrate your cloud with your IT system?
A high-performing IT system relies on tools that communicate with each other. As long as your file management remains isolated, your teams will have to compensate manually.
Document silos
The ERP has its attachments, the CRM has its own, and so does the HRIS. The same document exists in three versions, and none of them is the source of truth.
Hours lost to manual tasks
Creating an account, uploading a file, setting permissions: every manual action takes time and eventually leads to errors.
Data flows outside the IT system
Without an official integration, teams resort to makeshift third-party tools. Your files then transit through servers you don't control.
Fragile proprietary connectors
Developed for a specific need, but never maintained. Everything breaks at the first update.

The Voltn API: what are the use cases?
ERP, CRM, and business software
Your client files live in the ERP, while their documents reside in Voltn. The API synchronizes both, ensuring every supporting document is filed in the right place at the right stage, with no manual data entry.
HRIS and HR processes
When a new employee joins, their Voltn account is created with the appropriate permissions. They can view their payslips and contracts in a secure space, with every access logged.
+ compliance
Archiving and compliance
At the end of a file or upon reaching a regulatory deadline, your documents are automatically filed and archived in the designated folder structure. Audit logs track every movement.
never up to date
via API
Business workflows
When a validation occurs or a status changes, the document is automatically filed, shared, or archived. Your document processes keep pace with your business events.
