API ETL Configuration and Adapter Extension Guide

Default Configuration Example

The following is a sample configuration (DEFAULT_CONFIG) that enables connection to an example API. This configuration is used to control authentication, data source connection, and field mappings for an adapter:

DEFAULT_CONFIG = {
    "auth_type": "basic",  # Options: noauth, basic, bearer
    "auth_basic_username": "<USERNAME>",  # Basic auth username
    "auth_basic_password": "<PASSWORD>",  # Basic auth password
    "auth_bearer_token": "",  # Bearer token for 'bearer' auth_type

    "source_http_method": "post",  # HTTP method for requests.request
    "source_url": "http://41.175.18.170:8070/api/mobile/v1/beneficiary/active/search",
    "source_headers": {
        "Content-Type": "application/x-www-form-urlencodedc",
        "Accept": "application/json"
    },
    "source_batch_size": 50,  # Number of records to fetch in one batch

    "adapter_first_name_field": "firstName",
    "adapter_last_name_field": "lastName",
    "adapter_dob_field": "dateOfBirth",

    "skip_integration_test": False  # Must be False for production deployments
}

Creating a New Adapter

To implement a new adapter, you must:

1. Extend the base Adapter class provided by the project.

   • Base Adapter class source: base.py

2. Create a new class that inherits from this base class.

   • Reference implementation: exampleIndividialAdapter.py

3. Implement the required methods and logic in your subclass based on the data structure and behavior needed.

4. Register the adapter in the appropriate place if required for discovery or configuration.

Example

from api_etl.adapters.base import BaseAdapter

class MyCustomAdapter(BaseAdapter):
    def transform(self, record):
        # Implement transformation logic here
        pass

This modular architecture allows easy customization and extension to support different data sources and APIs.
