Why teams connect Klaviyo and Scaleway Postgres
Mirror Klaviyo's data into Scaleway Postgres 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 Klaviyo 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 Scaleway Postgres.
Stacksync mirrors Metrics, Campaigns, Flows, Templates from Klaviyo into Views, Materialized views, Schemas, Sequences in Scaleway Postgres 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 Klaviyo, so the tool and the database never disagree.
Common use cases
- Mirror campaign and flow engagement events into a warehouse for revenue attribution alongside order data
- Keep suppression and consent status consistent between Klaviyo and other email or SMS tools
- Back internal tools with the same Postgres instance while Stacksync keeps it consistent with external systems
- Keep an EU-hosted Postgres as the system of record while distributing data to US-hosted SaaS applications
Read Klaviyo with a query
Records from Klaviyo are ordinary rows in Scaleway Postgres; join them, index them, and use them in application logic without touching the vendor API.
Automate Klaviyo from your codebase
Write to the synced tables in Scaleway Postgres and Stacksync propagates the change into Klaviyo, replacing custom integration code.
React to changes as they happen
Updates in Klaviyo arrive as row changes in Scaleway Postgres, so triggers, jobs, and services can respond in near real time.
What you can sync between Klaviyo and Scaleway Postgres
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.
| Klaviyo objects | Scaleway Postgres objects | |
|---|---|---|
| Profiles Person records with arbitrary custom properties are the target for CRM and warehouse-sourced attributes. | Tables Primary sync unit; each table maps to an object or table on the other side of the sync. | |
| Lists Static audience memberships sync in from CRMs and forms for targeting. | Views Read-only sources for shaping data before it leaves the database. | |
| Segments Dynamic audiences are readable so other tools can mirror who qualifies. | Materialized views Precomputed result sets that can be read on a schedule for downstream syncs. | |
| Events Timestamped behavioral records tied to metrics; external order and product events are pushed in to trigger flows. | Schemas Namespace tables so multiple applications or environments can be synced selectively. | |
| Metrics Event type definitions organize the activity stream used in segmentation and attribution. | Sequences Generate primary keys; sync tooling must respect them when writing rows. | |
| Campaigns Email and SMS sends expose performance data for warehouse-based reporting. | Columns Postgres-native types, including JSONB and arrays, are mapped to fields in the paired system. |

How the Klaviyo and Scaleway Postgres connectors work
Klaviyo
- Integration surface
- REST API compliant with the JSON:API specification
- Authentication
- OAuth 2.0 for apps or private API keys
- Change detection
- Polling on updated timestamps; outbound webhooks exist for event topics (availability depends on plan or app-partner status) and as flow webhook actions
- Capabilities
- read · write · webhooks
- Rate limits
- Per-endpoint burst and steady rate limits apply
Scaleway Postgres
- Integration surface
- SQL wire protocol (PostgreSQL)
- Authentication
- Database credentials (username/password over TLS)
- Change detection
- Log-based CDC via PostgreSQL logical replication where the managed instance permits it; otherwise timestamp or query-based polling
- Capabilities
- read · write · CDC
- Rate limits
- Throughput is bounded by instance size and connection limits rather than API quotas

FAQ
Klaviyo and Scaleway Postgres integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Klaviyo and Scaleway Postgres: authenticate both systems, choose the objects to sync (such as Klaviyo's Profiles and Lists), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Klaviyo and Scaleway Postgres connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Klaviyo–Scaleway Postgres integration in-house.
-
Yes — Stacksync ships production-grade connectors for both Klaviyo and Scaleway Postgres. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
-
Change detection on Klaviyo: Polling on updated timestamps; outbound webhooks exist for event topics (availability depends on plan or app-partner status) and as flow webhook actions. On Scaleway Postgres: Log-based CDC via PostgreSQL logical replication where the managed instance permits it; otherwise timestamp or query-based polling. Each detected change propagates to the other side in milliseconds, with field-level conflict resolution and an inspectable event log.
-
On the Klaviyo side: Metrics, Campaigns, Flows, Templates, plus custom fields where Klaviyo exposes them. On the Scaleway Postgres side: Views, Materialized views, Schemas, Sequences. Stacksync auto-detects both schemas and converts types between the two systems.
-
Yes. Each object mapping can be bidirectional or restricted to a single direction (both systems accept writes). Read-only mirrors, one-way pushes, and full two-way sync can be mixed in the same integration.
