Why teams connect Customer.io and Scaleway Postgres
Mirror Customer.io'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 Customer.io 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 Deliveries / Messages, Newsletters, People, Objects from Customer.io into Materialized views, Schemas, Sequences, Columns 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 Customer.io, so the tool and the database never disagree.
Common use cases
- Keep unsubscribe and subscription-preference state consistent between Customer.io and the CRM to avoid compliance gaps.
- Sync account-level objects and their person relationships for B2B messaging keyed to company attributes.
- Run a two-way sync between Scaleway Postgres and SaaS tools so edits made in either system converge on the same rows
- Replicate the application database into a warehouse for analytics without writing custom pipelines
Read Customer.io with a query
Records from Customer.io are ordinary rows in Scaleway Postgres; join them, index them, and use them in application logic without touching the vendor API.
Automate Customer.io from your codebase
Write to the synced tables in Scaleway Postgres and Stacksync propagates the change into Customer.io, replacing custom integration code.
React to changes as they happen
Updates in Customer.io arrive as row changes in Scaleway Postgres, so triggers, jobs, and services can respond in near real time.
What you can sync between Customer.io 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.
| Customer.io objects | Scaleway Postgres objects | |
|---|---|---|
| Campaigns Automated workflows whose membership and metrics can be read via the App API. | Sequences Generate primary keys; sync tooling must respect them when writing rows. | |
| Broadcasts One-off sends to segments or audiences, triggerable via API. | Columns Postgres-native types, including JSONB and arrays, are mapped to fields in the paired system. | |
| Deliveries / Messages Per-recipient message records whose lifecycle events flow out through reporting webhooks. | Tables Primary sync unit; each table maps to an object or table on the other side of the sync. | |
| Newsletters Recurring email sends with performance metrics available for reporting syncs. | Views Read-only sources for shaping data before it leaves the database. | |
| People Profiles with attributes, matched on identifiers like id or email; the main write target of data syncs. | Materialized views Precomputed result sets that can be read on a schedule for downstream syncs. | |
| Objects Non-person entities such as accounts or companies, related to people for account-level messaging. | Schemas Namespace tables so multiple applications or environments can be synced selectively. |

How the Customer.io and Scaleway Postgres connectors work
Customer.io
- Integration surface
- REST APIs split by purpose: Track API for data ingestion, App API for campaigns, people lookups, and messages
- Authentication
- Basic auth with site ID and API key for the Track API; bearer token for the App API
- Change detection
- Reporting webhooks push message and delivery events; person attribute changes are not streamed and require source-side detection
- Capabilities
- read · write · webhooks
- Rate limits
- Subject to per-API rate limits documented by Customer.io
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
Customer.io and Scaleway Postgres integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Customer.io and Scaleway Postgres: authenticate both systems, choose the objects to sync (such as Customer.io's Campaigns and Broadcasts), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
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.

Common patterns for Customer.io and Scaleway Postgres: Read Customer.io with a query; Automate Customer.io from your codebase; React to changes as they happen. Records from Customer.io are ordinary rows in Scaleway Postgres; join them, index them, and use them in application logic without touching the vendor API.
-
Customer.io: REST APIs split by purpose: Track API for data ingestion, App API for campaigns, people lookups, and messages. Authentication: Basic auth with site ID and API key for the Track API; bearer token for the App API. Scaleway Postgres: SQL wire protocol (PostgreSQL). Authentication: Database credentials (username/password over TLS). Stacksync manages authentication, retries, and rate limits on both sides.
-
Customer.io: Reporting webhooks emit granular message lifecycle events, which is the practical way to get engagement data out at scale. Scaleway Postgres: Postgres-native types such as JSONB and arrays are available, and a sync layer must map them onto flat SaaS field types. Stacksync's field mapping accounts for these differences between Customer.io and Scaleway Postgres 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 Customer.io and Scaleway Postgres records are not retained after a sync operation.
