Why teams connect DuckDB and Stripe

Work with Stripe's financial data straight from DuckDB: read it with ordinary queries, write to it from your own code, and let Stacksync keep both sides consistent.

Engineers need finance data more often than finance systems make it easy to get: for internal tools, reporting services, or logic that reacts to invoices and payments. Working through the vendor API means rate limits, pagination, and glue code that has to be maintained forever.

Stacksync mirrors Prices, Refunds, Disputes, Payouts from Stripe into Database files, Schemas, Tables, Views in DuckDB and keeps the two in sync bi-directionally and in real time. Your services read finance records with normal queries against DuckDB, and rows your code writes or updates flow back into Stripe with validation, so the finance system stays the system of record.

Common use cases

  • Keep the product and price catalog aligned between Stripe and an internal database that other systems read
  • Trigger provisioning or deprovisioning in internal systems when subscription status changes
  • Sync SaaS data to Parquet on object storage and query it with DuckDB without standing up a warehouse.
  • Push aggregates computed in DuckDB out to a CRM or business tools so analysis results reach operational systems.

React to financial events

Changes in Stripe appear in DuckDB as row changes, so you can trigger downstream logic with the database tooling you already use.

Query finance data like any other data

Customers, invoices, and payments from Stripe live in DuckDB as regular tables or collections your team can join, index, and query.

Internal tools without API plumbing

Build dashboards and back-office tools directly on DuckDB; Stacksync handles the API calls, rate limits, and retries against Stripe.

What you can sync between DuckDB and Stripe

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.

DuckDB objects Stripe objects
Schemas Namespaces within a database used to organize tables in sync outputs. Invoices Billing documents with line items, synced to ERPs and accounting systems.
Tables Columnar tables created via SQL; the destination for materialized sync data. Subscriptions Recurring billing state that drives provisioning and CRM lifecycle stages.
Views SQL views used to shape or filter data for downstream consumers. Products Catalog entries kept aligned with internal product databases.
External files (Parquet/CSV/JSON) Files DuckDB queries in place without loading, common as a sync interchange format. Prices Amounts and billing intervals attached to products.
Attached databases Additional database files or external systems attached into one session for cross-source queries. Refunds Reversals synced into finance systems for accurate revenue reporting.
Database files Single-file .duckdb databases that jobs read and write directly on disk or object storage. Disputes Chargebacks that support and finance teams track in their own tools.

How the DuckDB and Stripe connectors work

DuckDB

Integration surface
In-process SQL engine via client libraries (Python, Node.js, JDBC, CLI); no server or network API by default
Authentication
None built in; access control is file-system level (MotherDuck adds token auth for its hosted service)
Change detection
Polling or full re-reads; no change feed or transaction log API
Capabilities
read · write
Rate limits
No API rate limits; throughput is bounded by local compute and I/O

Stripe

Integration surface
REST API
Authentication
API keys (secret and restricted keys); OAuth 2.0 for Stripe Connect platforms
Change detection
Webhooks backed by the Events API; /v1/events supports replay and backfill
Capabilities
read · write · webhooks
Rate limits
Subject to documented per-mode request rate limits; idempotency keys make retries safe
