This example assumes you have exported the access token to the variable $TOKEN.

Retrieve the LST template.
The template of a configuration element is a data structure containing all required sub-elements and supported attributes with their default values, along with any specified optional sub-elements.
```
curl -X GET -o response.xml \
    --header "Accept: application/xml" \
    --header "Authorization: Bearer $TOKEN" \
    "https://10.0.0.2/rest/v1.1/configuration/lst/lstfile"
```
The response is saved to the file response.xml.
Copy the content between the opening and closing <LSTFile> tags to a new file called lst-file.xml.
If you are on a Linux system with xmllint installed, you may optionally format the XML before writing it to the file system.
```
sed -n '/<LSTFile>/,/<\/LSTFile>/p' response.xml | xmllint --format - > lst-file.xml
```
Set the filename, realm, encryption, and secret parameters to their desired values.
The following shows an example of the contents of lst-file.xml:
```
<?xml version="1.0"?>
<LSTFile>
  <filename/>
  <realm/>
  <encryption/>
  <secret/>
</LSTFile>
```

Acquire the configuration lock.

curl -X POST \
    --header "Accept: application/xml" \
    --header "Authorization: Bearer $TOKEN" \
    "https://10.0.0.2/rest/v1.1/configuration/lock"

Add the LST XML file to the Communications Broker.

curl -X POST \
    -d@lst-file.xml \
    --header "Accept: application/xml" \
    --header "Authorization: Bearer $TOKEN" \
    "https://10.0.0.2/rest/v1.1/configuration/lst/lstfile"

Release the configuration lock.

curl -X POST \
    --header "Accept: application/xml" \
    --header "Authorization: Bearer $TOKEN" \
    "https://10.0.0.2/rest/v1.1/configuration/unlock"
