## Welcome!

This collection contains Prefect integrations for working with Census.

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.

Some things you can do with this collection out-of-the-box include:
- Trigger a Census sync run and wait for it to finish [(see how)](#use-a-censussync-job-block-to-run-a-sync-and-wait-for-completion)
- Call a custom endpoint with a `CensusClient` using your `CensusCredentials` [(see how)](#call-a-custom-endpoint)


For information on how to get started with Census, refer to the [Census docs](https://docs.getcensus.com/).

## 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](https://orion-docs.prefect.io/).

### Installation

Install `prefect-census` with `pip`:

```bash
pip install prefect-census
```

A list of available blocks in `prefect-census` and their setup instructions can be found [here](https://PrefectHQ.github.io/prefect-census/#blocks-catalog).

### 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](https://docs.getcensus.com/basics/api#getting-api-access) section of the Census docs.

Once you have a Census API key, you can configure a `CensusCredentials` 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](https://orion-docs.prefect.io/ui/blocks/).

### 💡  **NOTE**
> All [Census Syncs are incremental](https://docs.getcensus.com/basics/core-concept#sync-behaviors), which means they only capture records that are new or changed data since the previous sync.


### Write and run a flow


#### Use a `CensusSync` job block to run a sync and wait for completion

```python
from prefect import flow
from prefect_census import (
    CensusCredentials, CensusSync, run_census_sync
)

census_sync = CensusSync(
    credentials=CensusCredentials(api_key="my_api_key"),
    sync_id=42
)

@flow
def my_census_flow():
    # do some setup
    
    run_census_sync(census_sync)
    
    # do some cleanup

```

#### **Get Census sync run info**:
```python
from prefect import flow

from prefect_census import CensusCredentials
from prefect_census.runs import get_census_sync_run_info

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

    return get_census_sync_run_info(
        credentials=credentials,
        run_id=42
    )

get_sync_run_info_flow()
```

#### **Call a custom endpoint**:
```python
from prefect import flow
from prefect_census import CensusCredentials
from prefect_census.client import CensusClient

@flow
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

my_flow(42)
```
