 # Magento 2 Eventbridge Notifier
+
 This repository adds an [aligent/async-events](https://github.com/aligent/magento-async-events) compatible notifier for submitting events to [Amazon EventBridge](https://aws.amazon.com/eventbridge/).
 
-## How to use
-This module only provides an implementation of the `EventBridgeNotifier`. The `NotifierFactoryInterface` does not know anything about it yet. Therefore, it must be hooked up to the factory depending on the implementation of the `NotifierFactory`.
+## Getting Started
 
-1. Hook the notifier to the notifier factory
-   * This depends on how your factory is setup, if you're using the reference implementation for `NotifierFactoryInterface`, then you have to add the following lines
-to a `di.xml`
+### Configure AWS Credentials
+An IAM role with the `events:PutEvents` action is required so that the notifier can relay events into Amazon EventBridge.
 
-```xml
-<type name="Aligent\AsyncEvents\Service\AsyncEvent\NotifierFactory">
-    <arguments>
-        <argument name="notifierClasses" xsi:type="array">
-            <item name="event_bridge" xsi:type="object">Aligent\EventBridge\Service\EventBridgeNotifier</item>
-        </argument>
-    </arguments>
-</type>
-```
-2. Run `bin/magento cache:clear`
-3. Create subscribers which use the new notifier using the `metadata` field.
+Under `Stores -> Services -> Amazon EventBridge` set the `Access Key ID` and the `Secret Access Key` and the `Region`. You
+can configure the source of the event and the event bus if necessary.

+
+### Create Subscription
 
-Example
-```sh
+```shell
 curl --location --request POST 'https://m2.dev.aligent.consulting:44356/rest/V1/async_event' \
 --header 'Authorization: Bearer TOKEN' \
 --header 'Content-Type: application/json' \
 --data-raw '{
     "asyncEvent": {
-        "event_name": "my.custom.hook",
+        "event_name": "example.event",
         "recipient_url": "Amazon Event Bridge ARN",
         "verification_token": "supersecret",
         "metadata": "event_bridge"
     }
 }'
 ```
