With the /firmware/fetch endpoint you can avoid having to manually upload large SPS firmware ISO files before upgrading. Instead, you can install SPS firmware files by providing a URL through the SPS REST API. This also makes it easier to download and install a new firmware image on multiple SPS instances simultaneously. Download requests are processed asynchronously, as indicated by the 202 Accepted HTTP response.
URL
POST https://<IP-address-of-SPS>/api/firmware/fetch
Cookies
Cookie name | Description | Required | Values |
---|---|---|---|
session_id | Contains the authentication token of the user | Required |
The value of the session ID cookie received from the REST server in the authentication response, for example, a1f71d030e657634730b9e887cb59a5e56162860. For more information on authentication, see Authenticate to the SPS REST API. NOTE: This session ID refers to the connection between the REST client and the SPS REST API. It is not related to the sessions that SPS records (and which also have a session ID, but in a different format). |
Operations
Operations with the /firmware/fetch endpoint include:
Operation | HTTP method | URL |
Notes |
---|---|---|---|
Start downloading a SPS firmware | POST | /api/firmware/fetch |
|
Retrieve the status of SPS firmware downloads |
GET |
/api/firmware/fetch |
|
Retrieve the status of a single SPS firmware download |
GET |
/api/firmware/fetch/<key-of-the-SPS-firmware-download> |
|
Cancel a SPS firmware download |
DELETE |
/api/firmware/fetch/<key-of-the-SPS-firmware-download> |
You can safely cancel running a SPS firmware file download while the status of the download is queued or in-progress. If you cancel running a firmware download while its status is in-progress, any partially downloaded files will be removed from SPS. However, the status information remains in the queue, and can be removed by sending a second DELETE request to the same URL. NOTE: After the firmware download and verification steps are completed, it is not possible to cancel the installation of the firmware. |
Remove status information of finished, failed, and cancelled downloads |
DELETE |
/api/firmware/fetch/<key-of-the-SPS-firmware-download> |
There is no automated procedure to remove outdated firmware downloads. You must remove them manually. |
Sample request
Example: Start downloading SPS firmware files
The following command starts downloading SPS firmware files.
curl -X POST -b "${COOKIE_PATH}" --data "@-" https://<IP-address-of-SPS>/api/firmware/fetch
{ |
"url": "https://example.com/sps.iso", |
"checksum": { |
"sha256": "e6837af0b5dcb5397c6bc8b52c0fb95aa49a3fea4303e274c7501f0857cb9b80" |
} |
} |
Elements of the request message body include:

Description |
Notes |
---|---|---|---|
url |
string |
| |
checksum |
object |
When SPS downloads from a HTTPS URL, the server certificate is not validated during the SSL handshake. As a result, a checksum is required so that SPS can verify that the data was not tampered with in transit. The SPS download page for the respective version of the product provides the SHA-256 checksum of all official SPS images. |
checksum is a required parameter and can only accept a sha256 hash as a value. This parameter must be used when you are running SPS in a production environment. |
checksum.sha256 |
string |
The SHA-256 hash of the SPS ISO image. |

Elements of the response message body include:
Element |
Type |
Description |
Notes |
---|---|---|---|
key |
string |
The identifier of the SPS firmware download job that is running in the background. |
|
bytes_downloaded |
number |
The number of bytes already downloaded. |
|
bytes_total |
number |
The total number of bytes to be downloaded from the Content-Length header received from the server. |
|
error |
string |
The error message, containing details of the error. |
If no error has happened, then the value is null. |
info |
string |

Possible values:
The value of the info field can be null in two scenarios:
|
slot_id |
number |
The identifier of theSPS firmware image slot. |
Before the firmware download is finished, the value of the slot_id is null. When the status of the firmware download is finished, the slot_id indicates the location where the downloaded firmware was installed. Note that if an administrator later runs other operations on that particular firmware slot, like deleting it or uploading another firmware, then these will not be reflected in the status of the firmware download. |
start_time |
string (ISO 8601) |
The time at which the SPS firmware download job has started. |
|
status |
string |
The status of the SPS firmware fetching job. |
Possible values are:
|
url |
string(URI) |
The resource URL of the SPS firmware. |
