Why teams connect Customer.io and SAP Hana

Mirror Customer.io's data into SAP Hana 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 SAP Hana.

Stacksync mirrors Events, Segments, Campaigns, Broadcasts from Customer.io into Schemas, Sequences, Triggers, System-versioned temporal tables in SAP Hana 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

  • 01 Push CRM segments and lead status into Customer.io so messaging respects sales stage.
  • 02 Land delivery and engagement events (sent, opened, clicked, bounced) from reporting webhooks into a warehouse for attribution analysis.
  • 03 Detect inserts, updates, and deletes on high-write tables via AFTER triggers or a last-modified column and replicate the deltas downstream near-real-time.
  • 04 Read SYS.TABLES and TABLE_COLUMNS system views to auto-discover schema and generate field mappings when new tables are added to the sync.

Common sync patterns

Automate Customer.io from your codebase

Write to the synced tables in SAP Hana 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 SAP Hana, 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 SAP Hana

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 SAP Hana objects How this pairing syncs
People Profiles with attributes, matched on identifiers like id or email; the main write target of data syncs. System-versioned temporal tables Column store tables with a history table tracking each row's validity period; used to reconstruct update and delete history for change capture. People is specific to Customer.io and System-versioned temporal tables to SAP Hana — each maps to any object or custom field on the other side.
Objects Non-person entities such as accounts or companies, related to people for account-level messaging. System views (SYS schema) Catalog and monitoring views such as SYS.TABLES and TABLE_COLUMNS; read to discover schema and auto-generate field mappings for new tables. Objects is specific to Customer.io and System views (SYS schema) to SAP Hana — each maps to any object or custom field on the other side.
Events Behavioral events sent via the Track API that trigger campaigns. Column store tables HANA's default table type, optimized for analytics; synced two-way as rows over the SQL interface with the primary key driving upserts and delete tracking. Events is specific to Customer.io and Column store tables to SAP Hana — 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. Row store tables OLTP-oriented tables held fully in memory; read and written the same way through the SAP HANA client for high-write operational tables. Segments is specific to Customer.io and Row store tables to SAP Hana — 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. Calculation views Modeled analytic views over base tables; read-only sources for pushing aggregated or joined results into a warehouse or downstream app. Campaigns is specific to Customer.io and Calculation views to SAP Hana — each maps to any object or custom field on the other side.
Broadcasts One-off sends to segments or audiences, triggerable via API. SQL views Standard database views; read-only projections synced outbound when the source data should not be exposed as raw base tables. Broadcasts is specific to Customer.io and SQL views to SAP Hana — each maps to any object or custom field on the other side.

How changes propagate between Customer.io and SAP Hana

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 SAP Hana 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 SAP Hana as a row-level write, with types converted between the two schemas.

SAP Hana Customer.io Sub-second propagation

DetectionChanges in SAP Hana are captured at the source via change data capture — no polling loop against its API. Polling on a last-modified timestamp column, or AFTER INSERT/UPDATE/DELETE triggers writing to a shadow table.

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.
  • SAP Hana: No SaaS-style request quota; throughput is bounded by connection limits, statement memory caps, and workload-class admission control (concurrency/memory limits) that share capacity with production queries.

How the Customer.io and SAP Hana 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

SAP Hana

Integration surface
SQL over the SAP HANA client (JDBC/ODBC drivers); OData/REST via XS for app-layer access
Authentication
Dedicated database user credentials over an encrypted TLS connection (password sent hashed); Kerberos, SAML, JWT, and X.509 certificate authentication are also supported. SAP HANA Cloud enforces TLS and IP allowlisting.
Change detection
Polling on a last-modified timestamp column, or AFTER INSERT/UPDATE/DELETE triggers writing to a shadow table; system-versioned temporal tables and SLT/SDI provide trigger- and log-based CDC. No native webhooks.
Capabilities

Rate limits
No SaaS-style request quota; throughput is bounded by connection limits, statement memory caps, and workload-class admission control (concurrency/memory limits) that share capacity with production queries.
