Two-way sync
Changes in Apollo.io or Pendo instantly reflect in both systems. No stale data, no manual imports.
Keep Apollo.io and Pendo in sync without custom scripts. Cut weeks of integration work, eliminate silent data drift, and give your team a single, reliable source of truth.
Pendo turns data into dashboards, cohorts, and metrics; Apollo.io is where customers, contacts, deals, and activity actually live and change. The two meet wherever a number is really about a specific account, segment, or stage — yet most teams feed the CRM into analytics as a nightly extract or a hand-maintained connector, so the reporting lags the business and can't be sliced by the customers and segments that matter.
Stacksync syncs Tasks and calls, Custom fields, Contacts, Accounts from Apollo.io into Pendo field by field and within seconds, so every dashboard and cohort runs on current records instead of a stale copy. Because the connection runs both ways, the cohorts, scores, and metrics computed in Pendo write back to fields in Apollo.io, landing where the people working accounts can see them. You decide which system owns which fields; Stacksync keeps every copy consistent and resolves conflicts by rules you set.
The same account or person is keyed consistently in both systems, so a profile or row in Pendo lines up with the contact or account in Apollo.io.
A continuously synced copy of Apollo.io's records and activity in Pendo keeps a queryable history even as records change or age out of the CRM.
Accounts, contacts, deals, and activity from Apollo.io sync into Pendo, so metrics and dashboards group by real customers, segments, and stage instead of anonymous IDs.
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 | Pendo objects | How this pairing syncs | |
|---|---|---|---|
| Accounts Company records with firmographic attributes, matched to CRM accounts during sync. | Accounts Company/workspace records that roll visitors up to an account dimension; readable via Aggregation and a write target for custom fields (plan, ARR, health) via the Metadata API. | 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. | |
| Custom fields Account- and contact-level custom attributes mapped field-by-field in a sync. | Page Events Page-view events for tagged pages; read-only via the Aggregation API, used for adoption and path analysis in a warehouse. | Custom fields is specific to Apollo.io and Page Events to Pendo — 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. | Guide Events Guide seen/advanced/dismissed and step events for in-app walkthroughs; read-only through the Aggregation API to measure onboarding flow adoption. | Contacts is specific to Apollo.io and Guide Events to Pendo — 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. | Poll / NPS Responses Survey answers and NPS scores captured in-app (pollEvents / npsEvents); read-only via the Aggregation API as voice-of-customer data. | People (database records) is specific to Apollo.io and Poll / NPS Responses to Pendo — 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. | Features / Pages / Guides (metadata) Definitions of tagged UI elements listed through the entity endpoints; read-only reference used to label and join the event streams. | Sequences is specific to Apollo.io and Features / Pages / Guides (metadata) to Pendo — 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. | Visitors End-user records with agent-collected and custom fields; queried through the Aggregation API and enriched with custom fields written back via the Metadata API. | Deals (Opportunities) is specific to Apollo.io and Visitors to Pendo — each maps to any object or custom field on the other side. |
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.
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 Pendo through its API, with automatic retries and rate-limit backoff.

Real-time sync, workflow automation, event queues, EDI, and monitoring, for every Apollo.io–Pendo connection.
Changes in Apollo.io or Pendo instantly reflect in both systems. No stale data, no manual imports.
Trigger automated workflows whenever Apollo.io or Pendo data changes, update records, fire webhooks, or kick off sequences without brittle API scripts.
Handle millions of events per minute without losing a single Apollo.io or Pendo record.
Track your Apollo.io ⇄ Pendo sync health, view errors, and replay failed events in one click.
Transform legacy EDI complexity into simple database interactions between Apollo.io and Pendo.
Configure and sync within minutes, no code. Whether you sync 50k or 100M+ records, Stacksync handles the queues, infra, and plumbing. Integrations are non-invasive and need zero setup on your systems.
Authenticate Apollo.io and Pendo with each platform's native method — OAuth, API keys, or service accounts — plus secure options like SSH tunneling, IP whitelisting, and VPC peering.
Pick the Apollo.io and Pendo objects to sync — Stacksync auto-detects both schemas, including custom fields where the platform exposes them. Sync to existing tables, or let Stacksync create new ones with ideal data types.
Fields map automatically even when names and types differ. Stacksync handles transformation and type casting for you, zero configuration required.
Yes. Stacksync provides a managed, real-time two-way integration between Apollo.io and Pendo: authenticate both systems, choose the objects to sync (such as Apollo.io's Accounts and Custom fields), map fields visually, and changes propagate both ways in milliseconds — no code required.
Yes — Stacksync ships production-grade connectors for both Apollo.io and Pendo. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
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 Pendo: Polling - reads query the Aggregation API over event-time windows; no change-data-capture feed and no data-change webhooks. Writes go through the Metadata API on demand. Each detected change propagates to the other side in milliseconds, with field-level conflict resolution and an inspectable event log.
On the Pendo side: Feature Events, Page Events, Guide Events, Poll / NPS Responses, plus custom fields where Pendo 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.
Common patterns for Apollo.io and Pendo: One customer across analytics and CRM; A record that outlives edits in the CRM; Customer context in Pendo. The same account or person is keyed consistently in both systems, so a profile or row in Pendo lines up with the contact or account in Apollo.io.
