Why teams connect Couchbase and Lemlist

Mirror Lemlist's data into Couchbase so your own code can read and write it like any other table, with changes flowing both ways in seconds.

Engineers integrate with tools like Lemlist through APIs, which means auth, pagination, rate limits, webhooks, and retry logic, all maintained forever and all different for every tool. Meanwhile the data would be trivial to use if it simply lived in Couchbase.

Stacksync mirrors Unsubscribes, Webhooks, Team Members, Campaigns from Lemlist into Buckets, Scopes, Collections, JSON Documents in Couchbase and keeps both sides in sync in real time. Your services query the database directly, and inserts or updates your code makes flow back into Lemlist, so the tool and the database never disagree.

Common use cases

  • Propagate unsubscribes and bounces back to the CRM and other outreach tools for suppression compliance
  • Stop or pause sequences automatically when a reply converts to a deal in the CRM
  • Stream document mutations via DCP into downstream systems so caches, search indexes, or warehouses stay current.
  • Two-way sync between Couchbase (serving application data) and a CRM so support and sales teams see live application state.

One integration pattern for the whole stack

Every synced tool looks the same from the database, so each new integration is configuration, not a new codebase.

Read Lemlist with a query

Records from Lemlist are ordinary rows in Couchbase; join them, index them, and use them in application logic without touching the vendor API.

Automate Lemlist from your codebase

Write to the synced tables in Couchbase and Stacksync propagates the change into Lemlist, replacing custom integration code.

What you can sync between Couchbase and Lemlist

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.

Couchbase objects Lemlist objects
Scopes Namespaces inside a bucket used to group collections, similar to schemas. Unsubscribes Opt-out records propagate to other outreach tools and the CRM for compliance.
Collections Table-like groupings of documents that syncs typically map one-to-one to destination tables. Webhooks Hook subscriptions define which activity events are pushed to external endpoints.
JSON Documents The core records; schemaless JSON keyed by document id, flattened or mapped to relational rows in syncs. Team Members Sender and seat records map outreach activity to reps in other systems.
Global Secondary Indexes Indexes that make SQL++ query-based extraction efficient. Campaigns Outreach campaigns are the container leads are pushed into from CRMs and list-building workflows.
XDCR replications Cluster-to-cluster replication streams, useful context when choosing a sync source cluster. Leads Per-campaign prospect records sync in from enrichment sources and back out with status.
Full-text search indexes Search indexes over documents, relevant when syncing searchable content. Activities Engagement records such as opens, clicks, replies, and bounces sync to CRM timelines.
