<a id="s3-api-compatibility"></a>

This page documents S3 APIs supported by MinIO Object Storage. For reference documentation on any given API, see the corresponding documentation for Amazon S3.

> [!WARNING]

> MinIO strongly recommends using an [S3-Compatible SDK](/developers/minio-drivers/#minio-drivers) for performing object storage operations.

### MinIO alternatives for unsupported Bucket resources {#minio-alternatives-for-unsupported-bucket-resources}

- For calls to `BucketACL` or `ObjectACL` operations, use [Policies](/administration/identity-access-management/policy-based-access-control/#minio-policy).
- Calls to `BucketCORS` operations are not needed because CORS is enabled by default on all buckets for all HTTP verbs.
- For calls to `BucketWebsite` operations, use `caddy` or `nginx`.
- For calls to `BucketAnalytics`, `BucketMetrics`, or `BucketLogging` operations, use [Bucket Notifications](/administration/monitoring/bucket-notifications/#minio-bucket-notifications).
