Why teams connect Customer.io and YugabyteDB
Mirror Customer.io's data into YugabyteDB 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 YugabyteDB.
Stacksync mirrors Objects, Events, Segments, Campaigns from Customer.io into Materialized Views, Schemas, Sequences, CDC Streams in YugabyteDB 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
- Land delivery and engagement events (sent, opened, clicked, bounced) from reporting webhooks into a warehouse for attribution analysis.
- Keep unsubscribe and subscription-preference state consistent between Customer.io and the CRM to avoid compliance gaps.
- Sync reference data such as pricing or entitlements from an ERP into YugabyteDB for globally distributed low-latency reads.
- Consolidate data from regional YugabyteDB clusters into one reporting store.
Automate Customer.io from your codebase
Write to the synced tables in YugabyteDB 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 YugabyteDB, so triggers, jobs, and services can respond in near real time.
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.
What you can sync between Customer.io and YugabyteDB
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 | YugabyteDB objects | |
|---|---|---|
| Campaigns Automated workflows whose membership and metrics can be read via the App API. | Databases and Keyspaces Top-level containers for the YSQL (Postgres-style) and YCQL (Cassandra-style) APIs respectively. | |
| Broadcasts One-off sends to segments or audiences, triggerable via API. | Tables Distributed SQL tables split into tablets; the primary read and write targets. | |
| Deliveries / Messages Per-recipient message records whose lifecycle events flow out through reporting webhooks. | Indexes Global secondary indexes maintained transactionally alongside table writes. | |
| Newsletters Recurring email sends with performance metrics available for reporting syncs. | Materialized Views Precomputed query results available in YSQL for read-side shaping. | |
| People Profiles with attributes, matched on identifiers like id or email; the main write target of data syncs. | Schemas Postgres-style namespaces in YSQL used to organize synced data. | |
| Objects Non-person entities such as accounts or companies, related to people for account-level messaging. | Sequences ID generation objects relevant when syncing writes into YSQL tables. |

How the Customer.io and YugabyteDB 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
YugabyteDB
- Integration surface
- SQL wire protocol (PostgreSQL-compatible YSQL) plus a Cassandra-compatible YCQL API
- Authentication
- Database credentials
- Change detection
- Native CDC from the write-ahead log via PostgreSQL logical replication or Debezium-compatible connectors
- Capabilities
- read · write · CDC
- Rate limits
- No API rate limits; throughput scales with cluster nodes and tablet distribution.

FAQ
Customer.io and YugabyteDB integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Customer.io and YugabyteDB: 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.
-
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Customer.io and YugabyteDB connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Customer.io–YugabyteDB integration in-house.
-
Yes — Stacksync ships production-grade connectors for both Customer.io and YugabyteDB. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
-
Change detection on Customer.io: Reporting webhooks push message and delivery events; person attribute changes are not streamed and require source-side detection. On YugabyteDB: Native CDC from the write-ahead log via PostgreSQL logical replication or Debezium-compatible connectors. Each detected change propagates to the other side in milliseconds, with field-level conflict resolution and an inspectable event log.
-
On the Customer.io side: Objects, Events, Segments, Campaigns, plus custom fields where Customer.io exposes them. On the YugabyteDB side: Materialized Views, Schemas, Sequences, CDC Streams. 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.
