## Publish MinIO events via AMQP

Install RabbitMQ from [here](https://www.rabbitmq.com/).

### Step 1: Add AMQP endpoint to MinIO

The AMQP configuration is located under the sub-system `notify_amqp` top-level key. Create a configuration key-value pair here for your AMQP instance. The key is a name for your AMQP endpoint, and the value is a collection of key-value parameters described in the table below.

```
