and it would expect a response from that *external API* with a JSON body like:

```JSON

/// tip

Notice how the callback URL used contains the URL received as a query parameter in `callback_url` (`https://www.external.org/events`) and also the invoice `id` from inside of the JSON body (`2expen51ve`).

### Add the callback router

	MinIOTargetReplicationReady = "X-Minio-Replication-Ready"
