Why teams connect Box and PostgreSQL
Keep PostgreSQL and Box in step: a row in PostgreSQL for every file in Box, with names, paths, metadata, and status staying consistent in real time, in both directions.
A database holds structured records; a storage system holds the files those records depend on, such as contracts, images, exports, uploads, and documents. The two describe the same things from opposite sides: a row in PostgreSQL says a file exists and carries its name, location, and status, while Box holds the bytes. Linked only by a hand-kept path or a one-off script, the two drift the moment a file is renamed, moved, or deleted and the record still points at where it used to be.
Stacksync syncs Columns, Primary and Unique Keys, JSONB Columns, Sequences in PostgreSQL with Folders, Metadata, Collaborations, Users in Box bi-directionally and in real time. File attributes, including name, path or object key, size, type, modified time, owner, and tags or custom properties, map field by field to columns on the matching row, and a change on either side shows up on the other within seconds. New files appear as rows, metadata edits travel in the direction you choose, and deletes stay consistent, with conflict rules you set in place of nightly reconciliation scripts.
Common use cases
- 01 Feed reporting and BI from a continuously synced Postgres replica instead of scheduled ETL scripts
- 02 Expose SaaS objects (CRM contacts, ERP invoices, support tickets) as Postgres tables that internal tools can query and join
- 03 Stream enterprise Events (admin events) into a warehouse for audit, DLP, and access-review reporting.
- 04 Two-way sync of Files and Folders between Box and an operational database so applications track document status without calling the Box API directly.
Common sync patterns
Continuous archival to file storage
Rows from PostgreSQL are written out to Box as files on a schedule or as they change, giving a durable, low-cost copy for backup, compliance, or a data lake, without a custom export job to maintain.
A queryable index of the file store
Every file or object in Box shows up as a row in PostgreSQL, with its name, folder or key, size, type, and modified date as columns, so the contents of the store can be listed, filtered, and joined like any other table.
File metadata kept in step
Tags, custom properties, owner, or status columns edited on a row in PostgreSQL write back to the matching file's metadata in Box, and metadata changed in Box updates the row, so the two never disagree about a file.
What you can sync between Box and PostgreSQL
Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.
| Box objects | PostgreSQL objects | How this pairing syncs | |
|---|---|---|---|
| Users Managed and app users in the enterprise; provisioned, updated, and deprovisioned to keep Box access aligned with an HR or identity source. | Sequences Generate surrogate keys for rows created by inbound syncs. | Users is specific to Box and Sequences to PostgreSQL — each maps to any object or custom field on the other side. | |
| Groups Named user collections used for bulk collaboration; membership synced from a directory or IdP. | Custom Types and Enums Constrain synced values to a fixed set, mirroring picklist fields. | Groups is specific to Box and Custom Types and Enums to PostgreSQL — each maps to any object or custom field on the other side. | |
| Tasks Review or approval assignments on a file with due dates and states; read for workflow reporting or written to start approvals. | Tables The primary sync target; rows map one-to-one to records in connected SaaS systems. | Tasks is specific to Box and Tables to PostgreSQL — each maps to any object or custom field on the other side. | |
| Events Enterprise admin event stream, an audit log of uploads, deletes, logins, and shares across the account; read-only, consumed for reporting or change feeds. | Views Read-side projections used to expose joined or filtered data to a sync. | Events is specific to Box and Views to PostgreSQL — each maps to any object or custom field on the other side. | |
| Files Core content object with versions, name, size, and metadata; synced two-way so files and their attributes move between Box and a database or another store. | Materialized Views Precomputed result sets synced outward on a refresh schedule. | Files is specific to Box and Materialized Views to PostgreSQL — each maps to any object or custom field on the other side. | |
| Folders Hierarchical containers whose tree, names, and parent moves are mirrored so a target system reflects Box's structure; the account root is always folder ID 0. | Schemas Namespaces that scope which tables a sync reads and writes. | Folders is specific to Box and Schemas to PostgreSQL — each maps to any object or custom field on the other side. |
How changes propagate between Box and PostgreSQL
Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.
Box PostgreSQL Sub-second propagation
DetectionBox notifies Stacksync of record changes through webhook events. V2 webhooks fire on triggers such as FILE.UPLOADED, FILE.TRASHED, and METADATA_INSTANCE.UPDATED.
DeliveryEach detected change is applied to PostgreSQL as a row-level write, with types converted between the two schemas.
PostgreSQL Box Sub-second propagation
DetectionChanges in PostgreSQL are captured at the source via change data capture — no polling loop against its API. Logical replication (wal_level = logical) for change data capture via the "Postgres" connector.
DeliveryEach detected change is written to Box through its API, with automatic retries and rate-limit backoff.
Rate-limit considerations
- Box: Per user: 1,000 API calls per minute and 240 file uploads per minute; exceeding limits returns HTTP 429 with a Retry-After header. Box Business plans also carry a licensed monthly API-call allotment per enterprise.
- PostgreSQL: No API rate limits; throughput is bounded by connection limits, instance resources, and replication slot throughput.

FAQ
Box and PostgreSQL integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Box and PostgreSQL: authenticate both systems, choose the objects to sync (such as Box's Users and Groups), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Yes. Each object mapping can be bidirectional or restricted to a single direction (both systems accept writes). Read-only mirrors, one-way pushes, and full two-way sync can be mixed in the same integration.

Stacksync manages authentication, retries, and rate limits on both sides.
-
PostgreSQL: Renaming schemas, tables, or columns will break Stacksync configuration (requires manual sync configuration update). Box: The user Events API is consumed with a stream_position and long-polling; enterprise/admin events retain roughly one year of history and can lag strict ordering for near-real-time reads. Stacksync's field mapping accounts for these differences between Box and PostgreSQL without custom code.

Stacksync is SOC 2 Type II and ISO 27001 certified with HIPAA BAA support. Data is encrypted in transit, and a zero-persistent-storage architecture means Box and PostgreSQL records are not retained after a sync operation.
