# Python Script Data Source Template

## Overview

The Python Script data source template is a generic base template for any data source accessible through Python. It provides the foundation for connecting Validatar to REST APIs, custom databases, cloud services, and any other platform with a Python library.

This template is intentionally minimal — it provides the framework and expects customization for each specific use case.

**Platform:** Any (Python-accessible) **Connection Category:** Script **Template Category:** Built-in / Marketplace

## What's Included

### Connection Configuration

- Connection type: Python Script
- Parameters-driven configuration (no traditional connection string)

### Default Parameters

| Parameter | Type | Description |
| --- | --- | --- |
| `connection_string` | String | Generic connection string or URL |
| `api_key` | Secret | Authentication credential |

> **Note:** These are starting parameters. Customize them for your specific data source.

### Data Type Mappings

Includes mappings for common Python/JSON data types:

- `string` → String
- `integer`, `int` → Integer
- `number`, `float`, `double` → Decimal
- `boolean`, `bool` → Boolean
- `date` → Date
- `datetime` → DateTime
- `object`, `array` → Other

## Metadata Ingestion

Provides a template Python ingestion script that returns empty DataFrames with the expected structure. Customize this script for your specific data source.

## Profiling

Provides a template Python profiling script. Customize to calculate relevant metrics for your data source.

## Installation

If not already available, import from the Validatar Marketplace or create from scratch using the Script connection category.

## Customization

This template is designed to be customized. Key areas:

1. **Parameters** — Add parameters specific to your data source (URLs, credentials, configuration options)
2. **Ingestion script** — Write the Python script that discovers your data source's structure
3. **Profiling script** — Write the Python script that calculates data quality metrics
4. **Data types** — Map your data source's types to Validatar's internal types

See [Metadata Ingestion Scripts — Python Templates](/docs/metadata-ingestion-scripts-python-templates) and [Profiling Configuration — Python Templates](/docs/profiling-configuration-python-templates) for detailed guidance.
