Prefect integrations for working with Census syncs

Census is an Operational Analytics platform that enables you to sync your trusted analytics data from your hub into operational tools that your business teams use on a daily basis.

For information on how to get started with Census, refer to the Census docs.

Getting Started

Python setup

Requires an installation of Python 3.7+.

We recommend using a Python virtual environment manager such as pipenv, conda or virtualenv.

These tasks are designed to work with Prefect 2.0. For more information about how to use Prefect, please refer to the Prefect documentation.


Install prefect-census with pip:

pip install prefect-census

Then, register to view the block on Prefect Cloud:

prefect block register -m prefect_census

Note, to use the load method on Blocks, you must already have a block document saved through code or saved through the UI.

Get a Census API Key

You will need a Census API key to be able to use the integrations in this collection.

For directions for how to generate a Census API key, refer to the Getting API Access section of the Census docs.

Once you have a Census API key, you can configure a Census Credentials block in the Prefect UI for use with the integrations in this collection. For information about how to configure a block in the Prefect UI, refer to the Prefect docs.

Write and run a flow

Trigger Census sync run and wait for completion:

from prefect import flow

from prefect_census import CensusCredentials
from prefect_census.syncs import trigger_census_sync_run_and_wait_for_completion

def my_flow():
    creds = CensusCredentials(api_key="my_api_key")
    run_result = trigger_census_sync_run_and_wait_for_completion(


Get Census sync run info:

from prefect import flow

from prefect_census import CensusCredentials
from prefect_census.runs import get_census_sync_run_info

def get_sync_run_info_flow():
    credentials = CensusCredentials(api_key="my_api_key")

    return get_census_sync_run_info(


Call custom endpoint:

from prefect import flow
from prefect_census import CensusCredentials
from prefect_census.client import CensusClient

def my_flow(sync_id):
    creds_block = CensusCredentials(api_key="my_api_key")

    client = CensusClient(api_key=creds_block.api_key.get_secret_value())
    response = client.call_endpoint(http_method="GET", path=f"/syncs/{sync_id}")
    return response
