Why teams connect Apollo.io and Box

Keep the paperwork with the relationship: Apollo.io and Box share every customer's records and files in real time, in both directions.

Apollo.io 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 Done by hand, files drift away from the records they belong to and copies fall out of date.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 Accounts, People (database records), Sequences, Deals (Opportunities) in Apollo.io aligned with Users, Groups, Tasks, Events 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 Apollo.io; and records from Apollo.io 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 Land sequence enrollment status and outcomes in a warehouse for outbound performance reporting.
  • 02 Deduplicate contacts across Apollo and the CRM by syncing on email as the match key.
  • 03 Provision and deprovision Users, Groups, and Collaborations from an HR system or IdP so Box access follows onboarding and offboarding.
  • 04 Push generated documents from an ERP or contract system into Box Folders with the right Collaborations applied for the deal team.

Common sync patterns

One place for a customer's files

Attachments that accumulate against a record in Apollo.io collect in that customer's folder in Box, so the full document history lives in one place and is reachable by anyone who needs it.

A folder per account or deal

When an account or deal is created in Apollo.io, a matching folder or container opens in Box, named and organized the same way, so files have a home the moment they are needed.

Documents linked back to the record

A contract, proposal, or signed agreement filed in Box surfaces as a link on the matching record in Apollo.io, so the customer's paperwork sits with the relationship instead of a shared drive.

What you can sync between Apollo.io 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.

Apollo.io objects Box objects How this pairing syncs
People (database records) Prospects from Apollo's global database, pulled into downstream systems once enriched or saved. 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. People (database records) is specific to Apollo.io and Events to Box — each maps to any object or custom field on the other side.
Sequences Outreach cadences (emailer campaigns in the API); enrollment status is read to track which contacts are being worked. 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. Sequences is specific to Apollo.io and Files to Box — each maps to any object or custom field on the other side.
Deals (Opportunities) Pipeline records that can be read and written to keep Apollo aligned with the CRM of record. 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. Deals (Opportunities) is specific to Apollo.io and Folders to Box — each maps to any object or custom field on the other side.
Tasks and calls Rep activity records synced for activity reporting and coaching workflows. Metadata Structured key-value instances attached to files and folders via metadata templates; synced two-way with database columns for classification and search. Tasks and calls is specific to Apollo.io and Metadata to Box — each maps to any object or custom field on the other side.
Custom fields Account- and contact-level custom attributes mapped field-by-field in a sync. 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. Custom fields is specific to Apollo.io and Collaborations to Box — each maps to any object or custom field on the other side.
Contacts People saved to your Apollo account, synced with emails, phone numbers, and enrichment fields. Users Managed and app users in the enterprise; provisioned, updated, and deprovisioned to keep Box access aligned with an HR or identity source. Contacts is specific to Apollo.io and Users to Box — each maps to any object or custom field on the other side.

How changes propagate between Apollo.io 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.

Apollo.io Box Interval-based propagation

DetectionStacksync polls Apollo.io for changes on an incremental schedule, reading only records changed since the previous pass. Polling on updated-at timestamps.

DeliveryEach detected change is written to Box through its API, with automatic retries and rate-limit backoff.

Box Apollo.io 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 Apollo.io through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • Apollo.io: Rate limits and enrichment credits vary by plan; bulk endpoints are throttled separately from single-record calls.
  • 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.
