Box ↔ ProStream synchronization
Bridge Box — the enterprise content cloud used company-wide — and ProStream, the Dutch construction industry's primary contracts-and-submittals DMS. DMS Sync Manager keeps documents and metadata in step automatically, so no one copies between the general document store and the ProStream zaaknummer structure by hand.
How it works
Three steps to keep Box and ProStream in sync.
Connect Box and ProStream
Box authenticates with OAuth 2.0 against your Box enterprise. ProStream connects via an API key issued by your ProStream tenant administrator. Both connections are project-scoped and stored encrypted at rest.
Map Box folders to ProStream document sets
Pick a Box folder as the source (or destination) and a ProStream document set (or section) on the other side. Box metadata templates map to ProStream metadata — zaaknummer, doc type, fase — with direction set per sync task.
Filter by ProStream state and schedule
Sync only documents in the ProStream states that matter (Concept, Issued, Approved). Rules also filter by file type, label, or last-modified. Schedule hourly, daily, or on demand. Every run is logged file by file.
What customers do with it
A few real-world scenarios.
- Push ProStream-approved contract submittals into Box for company-wide access and external client sharing.
- Pull Box-managed correspondence and reference documents into the ProStream zaaknummer structure for the contracts record.
- Maintain a Box archive of every ProStream-issued submittal for retention, with revision history preserved as Box versions.
"Projects rarely fail in design — they fail when teams can't trust they're looking at the latest version."
Frequently asked questions
Are ProStream metadata fields (zaaknummer, doc type, fase) mapped to Box?
Yes. Each sync task lets you map ProStream metadata fields to Box metadata template fields and vice-versa, so both platforms stay searchable on the same identifiers.
Does ProStream's document state machine work with the sync?
Yes. Rules let you sync only documents in a chosen ProStream state (e.g. only Issued + Approved, never Concept). State changes can also trigger a sync run.
Is Box version history preserved?
Yes. Each new revision arrives as a new version in the destination, preserving Box's native version history. The ProStream revision identifier is written into a configurable Box metadata field.
Does this require a ProStream API license?
You need ProStream Connect API access enabled on your tenant — your ProStream administrator can confirm. DMS Sync handles all the rate limiting and reconnect logic.
Where is the data stored?
Sync workers run in eu-west-1 (Ireland). Files transit through the workers but are not retained; only metadata and audit logs are stored. For Box itself, EU data residency is available via Box Zones.
