# Use `InitiateJob` with an AWS SDK or CLI
<a name="glacier_example_glacier_InitiateJob_section"></a>

The following code examples show how to use `InitiateJob`.

Action examples are code excerpts from larger programs and must be run in context. You can see this action in context in the following code example:

Retrieve an archive from a vault. This example uses the ArchiveTransferManager class. For API details see [ArchiveTransferManager](https://docs.aws.amazon.com/sdkfornet/v3/apidocs/items/Glacier/TArchiveTransferManager).

#### [ CLI ]

**AWS CLI**  
The following command initiates a job to get an inventory of the vault `my-vault`:  

```
aws glacier initiate-job --account-id - --vault-name my-vault --job-parameters '{"Type": "inventory-retrieval"}'
```
Output:  

```
{
    "location": "/0123456789012/vaults/my-vault/jobs/zbxcm3Z_3z5UkoroF7SuZKrxgGoDc3RloGduS7Eg-RO47Yc6FxsdGBgf_Q2DK5Ejh18CnTS5XW4_XqlNHS61dsO4CnMW",
    "jobId": "zbxcm3Z_3z5UkoroF7SuZKrxgGoDc3RloGduS7Eg-RO47Yc6FxsdGBgf_Q2DK5Ejh18CnTS5XW4_XqlNHS61dsO4CnMW"
}
```
Amazon Glacier requires an account ID argument when performing operations, but you can use a hyphen to specify the in-use account.  
The following command initiates a job to retrieve an archive from the vault `my-vault`:  

```
aws glacier initiate-job --account-id - --vault-name my-vault --job-parameters file://job-archive-retrieval.json
```
`job-archive-retrieval.json` is a JSON file in the local folder that specifies the type of job, archive ID, and some optional parameters:  

```
{
  "Type": "archive-retrieval",
  "ArchiveId": "kKB7ymWJVpPSwhGP6ycSOAekp9ZYe_--zM_mw6k76ZFGEIWQX-ybtRDvc2VkPSDtfKmQrj0IRQLSGsNuDp-AJVlu2ccmDSyDUmZwKbwbpAdGATGDiB3hHO0bjbGehXTcApVud_wyDw",
  "Description": "Retrieve archive on 2015-07-17",
  "SNSTopic": "arn:aws:sns:us-west-2:0123456789012:my-topic"
}
```
Archive IDs are available in the output of `aws glacier upload-archive` and `aws glacier get-job-output`.  
Output:  

```
{
    "location": "/011685312445/vaults/mwunderl/jobs/l7IL5-EkXyEY9Ws95fClzIbk2O5uLYaFdAYOi-azsX_Z8V6NH4yERHzars8wTKYQMX6nBDI9cMNHzyZJO59-8N9aHWav",

}
```
