Why teams connect OpenSearch and Pendo

Give Pendo the users, events, and records that live in OpenSearch in real time, and sync the cohorts and scores Pendo computes back into OpenSearch where your applications read them.

A database holds the rows your business runs on: the users, events, orders, and records that every service reads and writes. Pendo is where people make sense of them, as dashboards, funnels, cohorts, and metrics. Moving the data from OpenSearch into Pendo usually means a hand-built extract or a change-data-capture pipeline that breaks the moment a column is renamed, and reporting that always trails last night's load.

Stacksync syncs Index templates, Ingest pipelines, Data streams, Snapshots in OpenSearch with Page Events, Guide Events, Poll / NPS Responses, Features / Pages / Guides (metadata) in Pendo in real time and in both directions. Operational rows flow into Pendo as they change, so dashboards read current data with no pipeline to maintain, and the segments, cohorts, or scores Pendo computes flow back into OpenSearch, where the applications and services that read from it get them at normal query latency. Field-level mapping, schema and type translation, and conflict resolution are handled for you.

Common use cases

  • 01 Sync Pendo Visitors and Accounts into a data model to score product-qualified accounts alongside behavioral event data.
  • 02 Load guide-engagement events into a reporting database to measure onboarding-flow adoption against retention and expansion.
  • 03 Stream CRM records such as accounts, contacts, and tickets into OpenSearch to power internal search across customer data.
  • 04 Sync product catalogs from an ERP or database into the indexes that back storefront search.

Common sync patterns

Analytics on live operational data, minus the pipeline

The users, events, orders, and records stored in OpenSearch land in Pendo as they change, so dashboards, funnels, and metrics run on current data instead of last night's extract.

One version of each user or account

A user, account, or record corrected in either system updates the other, so the identity your reports group by matches the identity your database stores.

Filter and grouping dimensions kept fresh

Attributes teams slice by, such as plan, region, or account owner, stay current in Pendo because they sync from OpenSearch as they change, instead of going stale after a one-time import.

What you can sync between OpenSearch and Pendo

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.

OpenSearch objects Pendo objects How this pairing syncs
Index aliases Stable names over rotating indexes, used for zero-downtime reindex during backfills 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. Index aliases is specific to OpenSearch and Accounts to Pendo — each maps to any object or custom field on the other side.
Index templates Mapping and settings presets applied to new indexes a sync creates 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. Index templates is specific to OpenSearch and Feature Events to Pendo — each maps to any object or custom field on the other side.
Ingest pipelines Server-side processors that transform documents as they are written Page Events Page-view events for tagged pages; read-only via the Aggregation API, used for adoption and path analysis in a warehouse. Ingest pipelines is specific to OpenSearch and Page Events to Pendo — each maps to any object or custom field on the other side.
Data streams Append-oriented time-series storage for logs and events pushed from source systems Guide Events Guide seen/advanced/dismissed and step events for in-app walkthroughs; read-only through the Aggregation API to measure onboarding flow adoption. Data streams is specific to OpenSearch and Guide Events to Pendo — each maps to any object or custom field on the other side.
Snapshots Backup artifacts, relevant when reseeding an index from a repository Poll / NPS Responses Survey answers and NPS scores captured in-app (pollEvents / npsEvents); read-only via the Aggregation API as voice-of-customer data. Snapshots is specific to OpenSearch and Poll / NPS Responses to Pendo — each maps to any object or custom field on the other side.
Indexes The core container; synced records land in indexes with defined mappings 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. Indexes is specific to OpenSearch and Features / Pages / Guides (metadata) to Pendo — each maps to any object or custom field on the other side.

How changes propagate between OpenSearch and Pendo

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.

OpenSearch Pendo Interval-based propagation

DetectionStacksync polls OpenSearch for changes on an incremental schedule, reading only records changed since the previous pass. No native change feed.

DeliveryEach detected change is written to Pendo through its API, with automatic retries and rate-limit backoff.

Pendo OpenSearch Interval-based propagation

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.

DeliveryEach detected change is written to OpenSearch through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • OpenSearch: Throughput bounded by cluster sizing rather than fixed API quotas.
  • Pendo: Pendo does not publish fixed numeric limits; it throttles heavy Aggregation queries with 429s and caps/paginates large responses, so wide exports are paced and time-windowed.

How the OpenSearch and Pendo connectors work

OpenSearch

Integration surface
REST API over HTTP(S) with JSON payloads
Authentication
basic authentication with the security plugin, or AWS IAM request signing on Amazon OpenSearch Service
Change detection
no native change feed; reads rely on queries with scroll or point-in-time polling
Capabilities
read · write
Rate limits
throughput bounded by cluster sizing rather than fixed API quotas

Pendo

Integration surface
Pendo Engage API (REST) on app.pendo.io (US) / app.eu.pendo.io (EU), base path /api/v1/ - Aggregation API for reads and the Metadata API for writes
Authentication
Integration key sent in the x-pendo-integration-key header, generated in Subscription Settings; keys are scoped read-only or read/write, so writes require a read/write key
Change detection
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.
Capabilities

Rate limits
Pendo does not publish fixed numeric limits; it throttles heavy Aggregation queries with 429s and caps/paginates large responses, so wide exports are paced and time-windowed.
