Why teams connect Gong and Klaviyo

Sync what happens in Klaviyo with the customer records in Gong, in real time and in both directions.

The CRM is supposed to be the record of every customer relationship, but customer-relevant information also accumulates in the other tools a team runs. Whatever Klaviyo holds or produces that touches a customer, whether conversations, payments, replies, enriched data, or notes, the CRM only benefits if it arrives without someone copying it over.

Stacksync connects Metrics, Campaigns, Flows, Templates in Klaviyo to Data Privacy (Erasure), Calls, Transcripts, Users in Gong with bi-directional, real-time sync. Activity and record changes in Klaviyo update the matching contact or account in Gong, and CRM data flows the other way wherever Klaviyo can store and use it.

Common use cases

  • 01 Mirror campaign and flow engagement events into a warehouse for revenue attribution alongside order data
  • 02 Keep suppression and consent status consistent between Klaviyo and other email or SMS tools
  • 03 Sync Interaction Stats such as talk ratios and per-rep activity into a coaching database for engagement and rep-performance dashboards.
  • 04 Import externally recorded dialer or web-conference calls into Gong via POST /v2/calls so they get transcribed and analyzed like native Gong calls.

Common sync patterns

Where Klaviyo can store CRM context: fields kept current

Owner, lifecycle stage, or account details from Gong sync into Klaviyo, so people working there have the context without switching tools.

Where Klaviyo runs outreach

Prospects, sends, and replies sync into Gong, keeping lead status current without manual imports.

Where Klaviyo supplies contact or company data

Enriched fields land directly on records in Gong, and refreshes keep them from going stale.

How changes propagate between Gong and Klaviyo

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.

Gong Klaviyo Interval-based propagation

DetectionStacksync polls Gong for changes on an incremental schedule, reading only records changed since the previous pass. Polling POST /v2/calls/extensive on fromDateTime/toDateTime.

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

Klaviyo Gong Sub-second propagation

DetectionKlaviyo notifies Stacksync of record changes through webhook events. Polling on updated timestamps.

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

Rate-limit considerations

  • Gong: 3 API calls per second and 10,000 calls per day per company by default; exceeding returns HTTP 429 with a Retry-After header, and limits can be raised by contacting Gong.
  • Klaviyo: Per-endpoint burst and steady rate limits apply.
