# Minio Golang Library for Amazon S3 Compatible Cloud Storage [](https://gitter.im/Minio/minio?utm_source=badge&utm_medium=badge&utm_campaign=pr-badge&utm_content=badge)
|
||||
The Minio Golang Client SDK provides simple APIs to access any Amazon S3 compatible object storage server.
|
||||
|
||||
**List of supported cloud storage providers.**
|
||||
**Supported cloud storage providers:**
|
||||
|
||||
- AWS Signature Version 4
|
||||
- Amazon S3
|
||||
- Minio
|
||||
|
||||
|
||||
- AWS Signature Version 2
|
||||
- Google Cloud Storage (Compatibility Mode)
|
||||
- Openstack Swift + Swift3 middleware
|
||||
- Ceph Object Gateway
|
||||
- Riak CS
|
||||
|
||||
This quickstart guide will show you how to install the client SDK and execute an example Golang program. For a complete list of APIs and examples, please take a look at the [Golang Client API Reference](https://docs.minio.io/docs/golang-client-api-reference) documentation.

|

|

ListenBucketNotification API receives bucket notification events through the

notification channel. The returned notification channel has two fields
|
||||
'Records' and 'Err'.
|
||||
|
||||
- 'Records' holds the notifications received from the server.
|
||||
- 'Err' indicates any error while processing the received notifications.
|
||||
|
||||
NOTE: Notification channel is closed at the first occurrence of an error.
