Why teams connect Customer.io and Tinybird
Get the data locked inside Customer.io into Tinybird as live tables, and send results back where Customer.io can use them, without writing a pipeline.
Whatever Customer.io is used for, it accumulates data the rest of the company wants to analyze, and that data usually sits behind an API rather than in the warehouse. Building and babysitting an extraction pipeline is the tax most teams pay for it.
Stacksync syncs Deliveries / Messages, Newsletters, People, Objects from Customer.io into tables in Tinybird continuously, handling schema, rate limits, and retries. Because the sync is bi-directional, results computed in Tinybird can also be written back into fields in Customer.io where the tool can use them.
Common use cases
- 01 Land delivery and engagement events (sent, opened, clicked, bounced) from reporting webhooks into a warehouse for attribution analysis.
- 02 Keep unsubscribe and subscription-preference state consistent between Customer.io and the CRM to avoid compliance gaps.
- 03 Compute aggregates in Tinybird and write the results back to CRM fields for scoring and routing.
- 04 Stream CRM activity such as deals and tickets into Tinybird Data Sources to power customer-facing dashboards.
Common sync patterns
Analytics on Customer.io's data
Records and events from Customer.io land in Tinybird as queryable tables, current within seconds and ready to join with the rest of the warehouse.
Cross-tool reporting
Combine Customer.io's data with data from every other synced system to answer questions no single tool can.
Where Customer.io accepts updates: operational write-back
Segments, scores, or reference values computed in Tinybird sync back onto records in Customer.io, putting analysis where the work happens.
What you can sync between Customer.io and Tinybird
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 | Tinybird objects | How this pairing syncs | |
|---|---|---|---|
| Events Behavioral events sent via the Track API that trigger campaigns. | Tokens Scoped credentials that control read and append rights per resource. | Events is specific to Customer.io and Tokens to Tinybird — each maps to any object or custom field on the other side. | |
| Segments Attribute- or event-based groups; data syncs feed the attributes segments evaluate. | Data Sources ClickHouse-backed tables that receive ingested rows; the write target for syncs into Tinybird. | Segments is specific to Customer.io and Data Sources to Tinybird — each maps to any object or custom field on the other side. | |
| Campaigns Automated workflows whose membership and metrics can be read via the App API. | Pipes Chained SQL nodes that transform Data Sources into query-ready results. | Campaigns is specific to Customer.io and Pipes to Tinybird — each maps to any object or custom field on the other side. | |
| Broadcasts One-off sends to segments or audiences, triggerable via API. | API Endpoints Published Pipe outputs exposed as parameterized HTTP queries; the main read surface. | Broadcasts is specific to Customer.io and API Endpoints to Tinybird — each maps to any object or custom field on the other side. | |
| Deliveries / Messages Per-recipient message records whose lifecycle events flow out through reporting webhooks. | Materialized Views Pipes materialized into new Data Sources for pre-aggregation at ingest time. | Deliveries / Messages is specific to Customer.io and Materialized Views to Tinybird — each maps to any object or custom field on the other side. | |
| Newsletters Recurring email sends with performance metrics available for reporting syncs. | Workspaces Project boundary that scopes Data Sources, Pipes, and tokens for a sync. | Newsletters is specific to Customer.io and Workspaces to Tinybird — each maps to any object or custom field on the other side. |
How changes propagate between Customer.io and Tinybird
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.
Customer.io Tinybird Sub-second propagation
DetectionCustomer.io notifies Stacksync of record changes through webhook events. Reporting webhooks push message and delivery events.
DeliveryEach detected change is applied to Tinybird as a row-level write, with types converted between the two schemas.
Tinybird Customer.io Interval-based propagation
DetectionStacksync polls Tinybird for changes on an incremental schedule, reading only records changed since the previous pass. Append-oriented ingestion.
DeliveryEach detected change is written to Customer.io through its API, with automatic retries and rate-limit backoff.
Rate-limit considerations
- Customer.io: Subject to per-API rate limits documented by Customer.io.
- Tinybird: Subject to the platform's ingestion and query rate limits; batch appends where possible.

FAQ
Customer.io and Tinybird integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Customer.io and Tinybird: authenticate both systems, choose the objects to sync (such as Customer.io's Events and Segments), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Change detection on Customer.io: Reporting webhooks push message and delivery events; person attribute changes are not streamed and require source-side detection. On Tinybird: Append-oriented ingestion; reads are pulled by querying published endpoints, no outbound CDC. 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: Deliveries / Messages, Newsletters, People, Objects, plus custom fields where Customer.io exposes them. On the Tinybird side: Tokens, Data Sources, Pipes, API Endpoints. 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.
-
Common patterns for Customer.io and Tinybird: Analytics on Customer.io's data; Cross-tool reporting; Where Customer.io accepts updates: operational write-back.
