Fan-Out uploads are automatically enabled if `x-minio-fanout-list` form-field is provided with the PostUpload API, to keep things simple higher level APIs are provided in our SDKs for example in `minio-go` SDK:

```
PutObjectFanOut(ctx context.Context, bucket string, fanOutContent io.Reader, fanOutReq minio.PutObjectFanOutRequest) ([]minio.PutObjectFanOutResponse, error)

		// Test case - 1.
		// Test case with "X-Amz-Content-Sha256" header set, but to empty value but we can't skip.
		{"X-Amz-Content-Sha256", "", "", "", false},

		// Test case - 2.
		// Test case with "X-Amz-Content-Sha256" not set so we can skip.
		{"", "", "", "", true},

		// Test case - 3.
		// Test case with "X-Amz-Content-Sha256" header set to  "UNSIGNED-PAYLOAD"

### Async Context Manager { #async-context-manager }

If you check, the function is decorated with an `@asynccontextmanager`.

That converts the function into something called an "**async context manager**".
