# Magento 2 Product Attribute Subscriber

> Configuration-based replacement for the prototype product-attribute-subscriber in the Legacy Magento 2 Connector.

## Overview

The **Product Attribute Subscriber** is a configuration-based subscriber that listens for product attribute data from a Magento 2 source system. It replaces the deprecated prototype-based `magento-2-roduct-attribute-subscriber` previously used in the Legacy Magento 2 Connector.

> [!NOTE]
>
> This component has been migrated from a prototype-based implementation to a configuration-based setup as part of the Legacy Magento 2 Connector replacement project.

## Prototype vs Configuration-based

> [!WARNING]
>
> This is an important behavioral difference to understand before setting up this component.

| | Prototype-based | Configuration-based |
| - | - | - |
| **Reusability** | Can be reused across different flows by changing a few fields | Not reusable across different purposes or payloads |
| **Flexibility** | One prototype can serve multiple use cases | (Not always) Each use case requires its own dedicated configuration |
| **How to reuse** | Modify fields directly | Duplicate the configuration and adjust as needed |

If you need to handle a different payload structure or use case, you must **duplicate** this Subscriber and adjust the configuration accordingly. Do not modify an existing configuration as another Route already uses it.

## Type

**Subscriber**

## Purpose

This Subscriber listens to Incoming product attribute data from Magento 2 and triggers the appropriate Route for further processing. It is used in flows where product attribute information needs to be synced or transformed to a target system.

## Configuration

| Parameter | Description | Required |
| - | - | - |
| `store_code` | The Magento 2 Store Code | Yes |
| `http-client` | The HTTP Client Authentication method used to connect to Magento 2 | Yes |
| `entity-schema` | The specific schema for the entity | No |

## Usage

1. Navigate to **Subscribers** in your Alumio environment.
2. Search for  **Magento 2 Product Attribute Subscriber**.
3. Configure the required parameters as described above.
4. Attach this Subscriber to the relevant route as the Incoming configuration.

## Notes

* Replaces the prototype: `magento-2-product-attribute-subscriber`
* Unlike the prototype-based implementation, this configuration-based Subscriber is **not reusable across different purposes or payloads**. If you need to handle a different payload structure or use case, you must duplicate this Subscriber and adjust the configuration accordingly.
* This Subscriber is typically used in product attribute sync flows.
