# Golang Admin Client API Reference [![Slack](https://slack.min.io/slack?type=svg)](https://slack.min.io)
The MinIO Admin Golang Client SDK provides APIs to manage MinIO services.
This quickstart guide will show you how to install the MinIO Admin client SDK, connect to MinIO admin service, and provide a walkthrough of a simple file uploader.
This document assumes that you have a working [Golang setup](https://golang.org/doc/install).
## Initialize MinIO Admin Client object.
## MinIO
```go
package main
import (
"fmt"
"github.com/minio/minio/pkg/madmin"
)
func main() {
// Use a secure connection.
ssl := true
// Initialize minio client object.
mdmClnt, err := madmin.New("your-minio.example.com:9000", "YOUR-ACCESSKEYID", "YOUR-SECRETKEY", ssl)
if err != nil {
fmt.Println(err)
return
}
// Fetch service status.
st, err := mdmClnt.ServerInfo()
if err != nil {
fmt.Println(err)
return
}
for _, peerInfo := range serversInfo {
log.Printf("Node: %s, Info: %v\n", peerInfo.Addr, peerInfo.Data)
}
}
```

## 5. Heal operations
<a name="Heal"></a>
### Heal(ctx context.Context, bucket, prefix string, healOpts HealOpts, clientToken string, forceStart bool, forceStop bool) (start HealStartSuccess, status HealTaskStatus, err error)
Start a heal sequence that scans data under given (possible empty)
`bucket` and `prefix`. The `recursive` bool turns on recursive
traversal under the given path. `dryRun` does not mutate on-disk data,
but performs data validation.
Two heal sequences on overlapping paths may not be initiated.
The progress of a heal should be followed using the same API `Heal`
by providing the `clientToken` previously obtained from a `Heal`
API. The server accumulates results of the heal traversal and waits
for the client to receive and acknowledge them using the status
request by providing `clientToken`.
__Example__
``` go
opts := madmin.HealOpts{
Recursive: true,
DryRun: false,
}
forceStart := false
forceStop := false
healPath, err := madmClnt.Heal(context.Background(), "", "", opts, "", forceStart, forceStop)
if err != nil {
log.Fatalln(err)
}
log.Printf("Heal sequence started at %s", healPath)
```

| `s.ClientAddress` | _string_ | Address of the client which initiated the heal operation, the client address has the form "host:port". |
| `s.StartTime` | _time.Time_ | Time when heal was initially started. |
#### HealTaskStatus structure
| Param | Type | Description |
|-------------------|--------------------|---------------------------------------------------|
| `s.Summary` | _string_ | Short status of heal sequence |
| `s.FailureDetail` | _string_ | Error message in case of heal sequence failure |
| `s.HealSettings` | _HealOpts_ | Contains the booleans set in the `HealStart` call |
| `s.Items` | _[]HealResultItem_ | Heal records for actions performed by server |
#### HealResultItem structure
| Param | Type | Description |
|------------------------|----------------|-----------------------------------------------------------------|
| `ResultIndex` | _int64_ | Index of the heal-result record |
| `Type` | _HealItemType_ | Represents kind of heal operation in the heal record |
