The Airbyte Python CDK is a framework for rapidly developing production-grade Airbyte connectors. The CDK currently offers helpers specific for creating Airbyte source connectors for:
HTTP APIs (REST APIs, GraphQL, etc..)
Generic Python sources (anything not covered by the above)
The CDK provides an improved developer experience by providing basic implementation structure and abstracting away low-level glue boilerplate.
This document is a general introduction to the CDK. Readers should have basic familiarity with the Airbyte Specification before proceeding.
If you have any issues with troubleshooting or want to learn more about the CDK from the Airbyte team, head to the #connector-development channel in our Slack to inquire further!
Generate an empty connector using the code generator. First clone the Airbyte repository then from the repository root run
then follow the interactive prompt. Next, find all
TODOs in the generated project directory -- they're accompanied by lots of comments explaining what you'll need to do in order to implement your connector. Upon completing all TODOs properly, you should have a functioning connector.
Additionally, you can follow this tutorial for a complete walkthrough of creating an HTTP connector using the Airbyte CDK.
If you want to learn more about the classes required to implement an Airbyte Source, head to our basic concepts doc.
If you have questions or are running into issues creating your first full refresh stream, head over to our full refresh stream doc. If you have questions about implementing a
parse_response function, this doc is for you.
Having trouble figuring out how to write a
stream_slices function or aren't sure what a
cursor_field is? Head to our incremental stream doc.
Airbyte recommends using the CDK template generator to develop with the CDK. The template generates created all the required scaffolding, with convenient TODOs, allowing developers to truly focus on implementing the API.
For tips on useful Python knowledge, see the Python Concepts page.

Setup a virtual env:
python -m venv .venvsource .venv/bin/activatepip install -e ".[dev]" # [dev] installs development-only dependencies
Iterate on the code locally
Run tests via
pytest -s unit_tests
Perform static type checks using
MyPy configuration is in
type_check_and_test.sh script bundles both type checking and testing in one convenient command. Feel free to use it!
All tests are located in the
unit_tests directory. Run
pytest --cov=airbyte_cdk unit_tests/ to run them. This also presents a test coverage report.
