Two-way sync
Changes in Gong or Lemlist instantly reflect in both systems. No stale data, no manual imports.
Keep Gong and Lemlist in sync without custom scripts. Cut weeks of integration work, eliminate silent data drift, and give your team a single, reliable source of truth.
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 Lemlist 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 Team Members, Campaigns, Leads, Activities in Lemlist to Users, Interaction Stats (Activity), Trackers & Scorecards, CRM Objects in Gong with bi-directional, real-time sync. Activity and record changes in Lemlist update the matching contact or account in Gong, and CRM data flows the other way wherever Lemlist can store and use it.
Enriched fields land directly on records in Gong, and refreshes keep them from going stale.
Owner, lifecycle stage, or account details from Gong sync into Lemlist, so people working there have the context without switching tools.
Prospects, sends, and replies sync into Gong, keeping lead status current without manual imports.
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.
| Gong objects | Lemlist objects | How this pairing syncs | |
|---|---|---|---|
| Library Call-library folders and folder content (curated calls and snippets) read via GET /v2/library/folders and /v2/library/folder-content. Read-only. | Unsubscribes Opt-out records propagate to other outreach tools and the CRM for compliance. | Library is specific to Gong and Unsubscribes to Lemlist — each maps to any object or custom field on the other side. | |
| Data Privacy (Erasure) GDPR/CCPA deletion handled by POST /v2/data-privacy/erase-data-for-email, with data-for-email lookups on the read side; a write path used for compliance deletions. | Webhooks Hook subscriptions define which activity events are pushed to external endpoints. | Data Privacy (Erasure) is specific to Gong and Webhooks to Lemlist — each maps to any object or custom field on the other side. | |
| Calls Retrieved via POST /v2/calls/extensive with participants, topics, trackers, scorecards, and media URLs, filtered by fromDateTime/toDateTime; external recordings are also imported via POST /v2/calls with media uploaded via PUT /v2/calls/{id}/media. Read and write. | Team Members Sender and seat records map outreach activity to reps in other systems. | Calls is specific to Gong and Team Members to Lemlist — each maps to any object or custom field on the other side. | |
| Transcripts Speaker-attributed, timestamped sentences retrieved via POST /v2/calls/transcript for one or more callIds; available only after asynchronous processing completes. Read-only. | Campaigns Outreach campaigns are the container leads are pushed into from CRMs and list-building workflows. | Transcripts is specific to Gong and Campaigns to Lemlist — each maps to any object or custom field on the other side. | |
| Users Gong users and team members with roles, titles, email, and settings, read via GET /v2/users to map call owners and participants to CRM and warehouse identities. Read-only. | Leads Per-campaign prospect records sync in from enrichment sources and back out with status. | Users is specific to Gong and Leads to Lemlist — each maps to any object or custom field on the other side. | |
| Interaction Stats (Activity) Aggregated talk/listen ratios, interaction stats, and day-by-day user activity retrieved via POST /v2/stats endpoints; read out for coaching and engagement reporting. Read-only. | Activities Engagement records such as opens, clicks, replies, and bounces sync to CRM timelines. | Interaction Stats (Activity) is specific to Gong and Activities to Lemlist — 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 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 Lemlist through its API, with automatic retries and rate-limit backoff.
DetectionLemlist notifies Stacksync of record changes through webhook events. Webhooks on outreach activity events, plus polling.

Real-time sync, workflow automation, event queues, EDI, and monitoring, for every Gong–Lemlist connection.
Changes in Gong or Lemlist instantly reflect in both systems. No stale data, no manual imports.
Trigger automated workflows whenever Gong or Lemlist data changes, update records, fire webhooks, or kick off sequences without brittle API scripts.
Handle millions of events per minute without losing a single Gong or Lemlist record.
Track your Gong ⇄ Lemlist sync health, view errors, and replay failed events in one click.
Transform legacy EDI complexity into simple database interactions between Gong and Lemlist.
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 Gong and Lemlist 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 Gong and Lemlist 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 Gong and Lemlist: authenticate both systems, choose the objects to sync (such as Gong's Library and Data Privacy (Erasure)), map fields visually, and changes propagate both ways in milliseconds — no code required.
Lemlist: Activity events such as replies, opens, bounces, and unsubscribes can be delivered via webhooks, enabling near real-time updates to CRM records without polling every campaign. Gong: Rate limits default to 3 API calls per second and 10,000 calls per day per company; exceeding returns HTTP 429 with a Retry-After header, and limits can be raised by contacting Gong. Stacksync's field mapping accounts for these differences between Gong and Lemlist 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 Gong and Lemlist records are not retained after a sync operation.
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Gong and Lemlist connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Gong–Lemlist integration in-house.
Yes — Stacksync ships production-grade connectors for both Gong and Lemlist. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
Change detection on Gong: Polling POST /v2/calls/extensive on fromDateTime/toDateTime; the public API exposes no outbound webhooks or CDC, though a Gong admin can configure a product-side automation Rule that POSTs matching calls to a URL. Transcripts and analysis appear only after asynchronous processing. On Lemlist: Webhooks on outreach activity events, plus polling. Each detected change propagates to the other side in milliseconds, with field-level conflict resolution and an inspectable event log.
