Why teams connect Apollo.io and Smartsheet
Sync what happens in Smartsheet with the customer records in Apollo.io, in real time and in both directions.
The CRM is supposed to be the record of every customer relationship, but customer-relevant information also accumulates in the other tools a team runs. Whatever Smartsheet holds or produces that touches a customer, whether conversations, payments, replies, enriched data, or notes, the CRM only benefits if it arrives without someone copying it over.
Stacksync connects Discussions and Comments, Users and Groups, Sheets, Rows in Smartsheet to Tasks and calls, Custom fields, Contacts, Accounts in Apollo.io with bi-directional, real-time sync. Activity and record changes in Smartsheet update the matching contact or account in Apollo.io, and CRM data flows the other way wherever Smartsheet can store and use it.
Common use cases
- 01 Trigger downstream actions in an operational database when a Row's status Cell changes, using sheet webhooks for near-real-time updates.
- 02 Two-way sync a project-tracker Sheet's Rows with a Postgres table so engineering works in SQL while project managers stay in Smartsheet.
- 03 Land sequence enrollment status and outcomes in a warehouse for outbound performance reporting.
- 04 Deduplicate contacts across Apollo and the CRM by syncing on email as the match key.
Common sync patterns
Where Smartsheet can store CRM context: fields kept current
Owner, lifecycle stage, or account details from Apollo.io sync into Smartsheet, so people working there have the context without switching tools.
Where Smartsheet supplies contact or company data
Enriched fields land directly on records in Apollo.io, and refreshes keep them from going stale.
What you can sync between Apollo.io and Smartsheet
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 | Smartsheet objects | How this pairing syncs | |
|---|---|---|---|
| Deals (Opportunities) Pipeline records that can be read and written to keep Apollo aligned with the CRM of record. | Rows Records inside a sheet, each with createdAt/modifiedAt and cells keyed by columnId; the primary unit synced to and from external tables. | Deals (Opportunities) is specific to Apollo.io and Rows to Smartsheet — 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. | Columns Define sheet schema and cell type (TEXT_NUMBER, DATE, CONTACT_LIST, PICKLIST, CHECKBOX); read via the API so field mappings can be generated. | Tasks and calls is specific to Apollo.io and Columns to Smartsheet — 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. | Cells Row-by-column values; writes must match the column type and no single cell can exceed 4,000 characters. | Custom fields is specific to Apollo.io and Cells to Smartsheet — 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. | Reports Read-only roll-ups spanning multiple sheets; pulled into a warehouse for cross-sheet reporting, capped at 50,000 rows. | Contacts is specific to Apollo.io and Reports to Smartsheet — each maps to any object or custom field on the other side. | |
| Accounts Company records with firmographic attributes, matched to CRM accounts during sync. | Attachments Files linked to rows or sheets; posting one carries a 10x rate cost, so bulk file sync is throttled to 30 per minute. | Accounts is specific to Apollo.io and Attachments to Smartsheet — each maps to any object or custom field on the other side. | |
| People (database records) Prospects from Apollo's global database, pulled into downstream systems once enriched or saved. | Discussions and Comments Threaded comments on rows and sheets; read out to sync collaboration history or activity into another system. | People (database records) is specific to Apollo.io and Discussions and Comments to Smartsheet — each maps to any object or custom field on the other side. |
How changes propagate between Apollo.io and Smartsheet
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 Smartsheet 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 Smartsheet through its API, with automatic retries and rate-limit backoff.
Smartsheet Apollo.io Sub-second propagation
DetectionSmartsheet notifies Stacksync of record changes through webhook events. Sheet-scoped webhooks subscribed to *.* events notify on row and cell changes.
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.
- Smartsheet: 300 requests per minute per access token; heavy calls like posting attachments cost 10x (30/min). A 429 returns errorCode 4003, back off ~60s.

-
Change detection on Apollo.io: Polling on updated-at timestamps; webhook callbacks exist only for delivering asynchronous enrichment results, not as a general change-event stream. On Smartsheet: Sheet-scoped webhooks subscribed to *.* events notify on row and cell changes; otherwise polling on sheet and row modifiedAt timestamps. Each detected change propagates to the other side in milliseconds, with field-level conflict resolution and an inspectable event log.
-
On the Smartsheet side: Discussions and Comments, Users and Groups, Sheets, Rows, plus custom fields where Smartsheet exposes them. On the Apollo.io side: Tasks and calls, Custom fields, Contacts, Accounts. Stacksync auto-detects both schemas and converts types between the two systems.
-
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.
