Why teams connect Affinity and Box
Keep the paperwork with the relationship: Affinity and Box share every customer's records and files in real time, in both directions.
Affinity holds the customer relationship as structured records; Box holds the files that belong to those relationships, from contracts and proposals to signed agreements and statements of work. The two are linked in practice and disconnected in software: someone downloads a document, renames it, and uploads it to the right folder, or exports records out to storage for retention. Done by hand, files drift away from the records they belong to and copies fall out of date.
Stacksync keeps List Entries, Persons, Organizations, Opportunities in Affinity aligned with Tasks, Events, Files, Folders in Box, in real time. A new account or deal can open its own folder in Box; a document filed in Box can surface as a link and metadata on the matching record in Affinity; and records from Affinity can be written into Box as files or objects for backup, archival, and compliance. You choose which side owns what, and Stacksync keeps the two consistent as either one changes.
Common use cases
- 01 Keep introductions and relationship data from Affinity aligned with outreach tools used by the team.
- 02 Sync notes and reminders into project or task systems used outside the deal team.
- 03 Two-way sync of Files and Folders between Box and an operational database so applications track document status without calling the Box API directly.
- 04 Mirror Metadata template instances on Files into database columns so contracts and assets are searchable and reportable alongside other business data.
Common sync patterns
Documents linked back to the record
A contract, proposal, or signed agreement filed in Box surfaces as a link on the matching record in Affinity, so the customer's paperwork sits with the relationship instead of a shared drive.
CRM records archived into storage
Records from Affinity are written into Box as files or objects on the schedule you set, giving you a durable copy for backup, retention, and compliance without an export to run by hand.
Document status on the record
Metadata kept in Box, such as document type, review state, or whether an agreement is signed, updates a field on the matching record in Affinity, so people working the account see where the paperwork stands without opening storage.
What you can sync between Affinity and Box
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.
| Affinity objects | Box objects | How this pairing syncs | |
|---|---|---|---|
| Field Values Custom field data, either global or scoped to a list, mapped field-by-field in syncs. | Collaborations Access grants linking a user or group to a file or folder with a role such as viewer, editor, or co-owner; written to manage sharing programmatically. | Field Values is specific to Affinity and Collaborations to Box — each maps to any object or custom field on the other side. | |
| Notes Meeting and call notes synced for record-keeping in other systems. | Users Managed and app users in the enterprise; provisioned, updated, and deprovisioned to keep Box access aligned with an HR or identity source. | Notes is specific to Affinity and Users to Box — each maps to any object or custom field on the other side. | |
| Interactions Automatically captured emails and meetings, read for activity reporting. | Groups Named user collections used for bulk collaboration; membership synced from a directory or IdP. | Interactions is specific to Affinity and Groups to Box — each maps to any object or custom field on the other side. | |
| Reminders Follow-up tasks associated with people and organizations. | Tasks Review or approval assignments on a file with due dates and states; read for workflow reporting or written to start approvals. | Reminders is specific to Affinity and Tasks to Box — each maps to any object or custom field on the other side. | |
| Lists Pipelines (deal flow, fundraising, portfolio) that structure most Affinity data; syncs usually target a specific list. | 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. | Lists is specific to Affinity and Events to Box — each maps to any object or custom field on the other side. | |
| List Entries The membership of a person, organization, or opportunity on a list, carrying its list-specific fields. | 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. | List Entries is specific to Affinity and Files to Box — each maps to any object or custom field on the other side. |
How changes propagate between Affinity and Box
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.
Affinity Box Sub-second propagation
DetectionAffinity notifies Stacksync of record changes through webhook events. Webhook subscriptions for record events, supplemented by polling.
DeliveryEach detected change is written to Box through its API, with automatic retries and rate-limit backoff.
Box Affinity 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 written to Affinity through its API, with automatic retries and rate-limit backoff.
Rate-limit considerations
- Affinity: Subject to the platform's published API rate limits.
- 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.
