Two-way sync
Changes in Affinity or Pendo instantly reflect in both systems. No stale data, no manual imports.
Keep Affinity 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; Affinity 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 Notes, Interactions, Reminders, Lists from Affinity 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 Affinity, 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.
A continuously synced copy of Affinity'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 Affinity sync into Pendo, so metrics and dashboards group by real customers, segments, and stage instead of anonymous IDs.
New records and status changes in Affinity appear in Pendo within seconds, so dashboards and cohorts track the current pipeline rather than last night's export.
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.
| Affinity objects | Pendo objects | How this pairing syncs | |
|---|---|---|---|
| Notes Meeting and call notes synced for record-keeping in other systems. | Feature Events Click/interaction events on tagged features, read-only through the Aggregation API over an event-time window and joined to the Feature definitions. | Notes is specific to Affinity and Feature Events to Pendo — each maps to any object or custom field on the other side. | |
| Interactions Automatically captured emails and meetings, read for activity reporting. | Page Events Page-view events for tagged pages; read-only via the Aggregation API, used for adoption and path analysis in a warehouse. | Interactions is specific to Affinity and Page Events to Pendo — each maps to any object or custom field on the other side. | |
| Reminders Follow-up tasks associated with people and organizations. | Guide Events Guide seen/advanced/dismissed and step events for in-app walkthroughs; read-only through the Aggregation API to measure onboarding flow adoption. | Reminders is specific to Affinity and Guide Events to Pendo — each maps to any object or custom field on the other side. | |
| Lists Pipelines (deal flow, fundraising, portfolio) that structure most Affinity data; syncs usually target a specific list. | Poll / NPS Responses Survey answers and NPS scores captured in-app (pollEvents / npsEvents); read-only via the Aggregation API as voice-of-customer data. | Lists is specific to Affinity and Poll / NPS Responses to Pendo — each maps to any object or custom field on the other side. | |
| List Entries The membership of a person, organization, or opportunity on a list, carrying its list-specific fields. | 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. | List Entries is specific to Affinity and Features / Pages / Guides (metadata) to Pendo — each maps to any object or custom field on the other side. | |
| Persons Contact records enriched with relationship intelligence, synced with CRMs and outreach tools. | 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. | Persons is specific to Affinity 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.
DetectionAffinity notifies Stacksync of record changes through webhook events. Webhook subscriptions for record events, supplemented by polling.
DeliveryEach detected change is written to Pendo through its API, with automatic retries and rate-limit backoff.
DetectionStacksync polls Pendo for changes on an incremental schedule, reading only records changed since the previous pass. Polling - reads query the Aggregation API over event-time windows.

Real-time sync, workflow automation, event queues, EDI, and monitoring, for every Affinity–Pendo connection.
Changes in Affinity or Pendo instantly reflect in both systems. No stale data, no manual imports.
Trigger automated workflows whenever Affinity 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 Affinity or Pendo record.
Track your Affinity ⇄ Pendo sync health, view errors, and replay failed events in one click.
Transform legacy EDI complexity into simple database interactions between Affinity 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 Affinity 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 Affinity 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 Affinity and Pendo: authenticate both systems, choose the objects to sync (such as Affinity's Notes and Interactions), map fields visually, and changes propagate both ways in milliseconds — no code required.
Pendo: Authentication is an integration key sent in the x-pendo-integration-key header; keys are created in Subscription Settings and can be scoped read-only or read/write, so writes require a read/write key. Affinity: Custom fields can be global or scoped to a single list, which affects how field mappings are defined per pipeline. Stacksync's field mapping accounts for these differences between Affinity and Pendo 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 Affinity and Pendo records are not retained after a sync operation.
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Affinity and Pendo connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Affinity–Pendo integration in-house.
Yes — Stacksync ships production-grade connectors for both Affinity and Pendo. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
Change detection on Affinity: Webhook subscriptions for record events, supplemented by polling. 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.
