fivetran-connector-sdk
Build custom connectors on Fivetran platform
Decision gist · record as of 2026-08-14
Yes, if you need to ingest data from a source Fivetran doesn't support and want to avoid building and hosting a separate connector service. The SDK is actively maintained, has low install friction, carries a permissive license, and integrates directly with Fivetran's platform. Install only if you have a specific unsupported source in mind and are comfortable writing Python code to define the connector logic.AI-flagged interpretation of the facts on this page — verify before relying

What it is and what it does
The fivetran-connector-sdk is a framework for writing custom data connectors that execute within Fivetran's managed cloud infrastructure. Instead of building a standalone service or relying on unsupported third-party connectors, you write Python code using the SDK's Connector, Logging, and Operations classes, and Fivetran handles scheduling, compute, and orchestration. The SDK is designed for scenarios where Fivetran lacks a native connector—private APIs, custom applications, unsupported file formats, or data that requires filtering or anonymization before reaching your destination.
The package provides a structured way to define how data is extracted from your source, transformed if needed, and delivered to Fivetran's platform. It depends on grpcio and grpcio-tools for communication, requests for HTTP operations, and utility libraries like tqdm and prompt-toolkit. The framework abstracts away infrastructure concerns, letting you focus on the connector logic itself.
Use it for
- Extract data from a proprietary internal API that Fivetran doesn't support natively.
- Pre-process or filter sensitive data before it enters your data warehouse.
- Build a connector for a custom file format or database that requires special handling.
- Integrate a private data source without exposing it to a third-party service.
- Anonymize or transform data on ingestion to meet compliance requirements.
