Why teams connect Customer.io and InfluxDB

Mirror Customer.io's data into InfluxDB 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 InfluxDB.

Stacksync mirrors Broadcasts, Deliveries / Messages, Newsletters, People from Customer.io into Measurements, Points, Tags, Fields in InfluxDB 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.
  • Feed alert-relevant thresholds and asset metadata from business systems into InfluxDB tags for richer queries.
  • Sync device and telemetry rollups from InfluxDB into a CRM or ERP so account teams see product usage and fleet health.

Read Customer.io with a query

Records from Customer.io are ordinary rows in InfluxDB; 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 InfluxDB 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 InfluxDB, so triggers, jobs, and services can respond in near real time.

What you can sync between Customer.io and InfluxDB

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 InfluxDB objects
People Profiles with attributes, matched on identifiers like id or email; the main write target of data syncs. Measurements The table-like grouping for points, typically mapped to a synced dataset.
Objects Non-person entities such as accounts or companies, related to people for account-level messaging. Points Individual time-stamped records, the unit of write via line protocol.
Events Behavioral events sent via the Track API that trigger campaigns. Tags Indexed key-value metadata used for filtering and as sync partition keys.
Segments Attribute- or event-based groups; data syncs feed the attributes segments evaluate. Fields The unindexed numeric or string values carried by each point.
Campaigns Automated workflows whose membership and metrics can be read via the App API. Retention policies Automatic expiry rules that determine how long synced history remains queryable.
Broadcasts One-off sends to segments or audiences, triggerable via API. Organizations Tenancy scope for tokens and buckets in multi-tenant deployments.

Trading partners

EDI

Transform legacy EDI complexity into simple database interactions between Customer.io and InfluxDB.

How the Customer.io and InfluxDB 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

InfluxDB

Integration surface
REST API with line-protocol writes; queries via InfluxQL, Flux, or SQL depending on version
Authentication
API token
Change detection
Polling with time-range queries; data is timestamped, so incremental reads use time cursors
Capabilities
read · write
Rate limits
Subject to the platform's API rate limits on cloud plans; self-hosted deployments are bounded by hardware.
