Why teams connect Apollo.io and Salesforce
Run Apollo.io and Salesforce side by side with the same accounts and contacts in both, whether they serve different teams or one is replacing the other.
Two CRMs in one company is more common than anyone plans for: an acquisition brings its own system, regions or business units standardize differently, or a migration is under way and both are live. In every case, some of the same companies and people exist in both systems, and every day of manual double entry pushes the copies further apart.
Stacksync syncs Deals (Opportunities), Tasks and calls, Custom fields, Contacts in Apollo.io with Tasks and Events, Products and Price Books, Custom Objects, Accounts in Salesforce in real time and in both directions, with field-level mapping and matching on identifiers you choose. Update a record in either CRM and the other reflects it within seconds.
Common use cases
- 01 Deduplicate contacts across Apollo and the CRM by syncing on email as the match key.
- 02 Push CRM opportunity stages back into Apollo so reps see pipeline context while sequencing.
- 03 Write product usage metrics computed in a warehouse onto Account and Contact fields so reps see adoption signals on the record.
- 04 Trigger provisioning or billing changes in an operational database when an Opportunity moves to closed-won.
Common sync patterns
Divisional or regional split
Where each CRM serves a different team or region, sync just the shared accounts and contacts so handoffs and cross-sell work.
Where both track pipeline: deal visibility across systems
Deal stage and value on shared accounts stay visible from either CRM.
Post-acquisition consolidation
Keep both CRMs accurate while the merged team decides on a target system, instead of freezing one and losing months of updates.
What you can sync between Apollo.io and Salesforce
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 | Salesforce objects | How this pairing syncs | |
|---|---|---|---|
| Contacts People saved to your Apollo account, synced with emails, phone numbers, and enrichment fields. | Contacts People linked to Accounts; synced two-way with marketing, support, and warehouse person records. | Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions. | |
| Accounts Company records with firmographic attributes, matched to CRM accounts during sync. | Accounts Company records that anchor most syncs; typically mapped to customer tables in a database or ERP. | Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions. Custom fields on either side are included in the mapping. | |
| Deals (Opportunities) Pipeline records that can be read and written to keep Apollo aligned with the CRM of record. | Cases Support records; synced with help desk tools or internal databases for escalation workflows. | Deals (Opportunities) is specific to Apollo.io and Cases to Salesforce — 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. | Campaigns Marketing membership data; read out for attribution analysis in the warehouse. | Tasks and calls is specific to Apollo.io and Campaigns to Salesforce — 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. | Tasks and Events Activity records; usually read-only in syncs to feed activity reporting. | Custom fields is specific to Apollo.io and Tasks and Events to Salesforce — 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. | Products and Price Books Catalog and pricing data; commonly mastered in an ERP and written into Salesforce. | People (database records) is specific to Apollo.io and Products and Price Books to Salesforce — each maps to any object or custom field on the other side. |
How changes propagate between Apollo.io and Salesforce
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 Salesforce 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 Salesforce through its API, with automatic retries and rate-limit backoff.
Salesforce Apollo.io Sub-second propagation
DetectionChanges in Salesforce are captured at the source via change data capture — no polling loop against its API. Apex triggers are used whenever possible (Salesforce actively notifies Stacksync via an Apex trigger + callout class + remote site setting).
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.
- Salesforce: Daily API request allocations vary by edition and license count.

FAQ
Apollo.io and Salesforce integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Apollo.io and Salesforce: authenticate both systems, choose the objects to sync (such as Apollo.io's Contacts and Accounts), 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.
-
Common patterns for Apollo.io and Salesforce: Divisional or regional split; Where both track pipeline: deal visibility across systems; Post-acquisition consolidation. Where each CRM serves a different team or region, sync just the shared accounts and contacts so handoffs and cross-sell work.
-
Apollo.io: REST API. Authentication: API key (passed in request headers); master keys unlock account-wide endpoints. Salesforce: REST, SOAP, and Bulk APIs. Authentication: OAuth login via a Salesforce user (browser-based authorization flow); requires "API Enabled" permission for polling mode, plus "Author Apex" and "Customize Application" OR "Modify All Data" for trigger mode. Stacksync manages authentication, retries, and rate limits on both sides.
-
Apollo.io: The API exposes both prospecting search endpoints and CRM-style CRUD endpoints for contacts, accounts, and deals. Salesforce: Records are queried with SOQL, and every standard and custom object carries a SystemModstamp field that sync engines use to order incremental changes. Stacksync's field mapping accounts for these differences between Apollo.io and Salesforce 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 Apollo.io and Salesforce records are not retained after a sync operation.
