Why teams connect Apollo.io and Freshsales

Run Apollo.io and Freshsales 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 Custom fields, Contacts, Accounts, People (database records) in Apollo.io with Accounts, Deals, Tasks, Appointments in Freshsales 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 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 Keep Freshsales accounts aligned with a billing system so plan and revenue fields stay current.
  • 04 Sync sales activities and appointments into analytics tools for rep productivity reporting.

Common sync patterns

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.

Migration with a parallel run

When one CRM is replacing the other, run both fully live until cutover, with no snapshot gap and no data freeze.

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.

How changes propagate between Apollo.io and Freshsales

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 Freshsales 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 Freshsales through its API, with automatic retries and rate-limit backoff.

Freshsales Apollo.io Sub-second propagation

DetectionFreshsales notifies Stacksync of record changes through webhook events. Polling with updated-at filters through views.

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.
  • Freshsales: Subject to per-account API rate limits that vary by Freshworks plan.
