    List parameter versions

    This page describes how to retrieve a list of all the parameter versions associated with a parameter within a specified Google Cloud project and location.

    Versions represent the specific setting or configuration value that the parameter holds at a given point in time. By looking at the list of versions, you can see how a parameter has changed over time and who made the change. This helps with auditing and troubleshooting. For example, if you're experiencing issues with your current configuration, examining disabled versions can help you understand what settings were previously used and potentially identify if a recent change caused the problem.

    Required roles

    To get the permissions that you need to list parameter versions, ask your administrator to grant you the Parameter Manager Parameter Viewer ( roles/parametermanager.parameterViewer ) IAM role on the parameter, project, folder, or organization. For more information about granting roles, see Manage access to projects, folders, and organizations .

    You might also be able to get the required permissions through custom roles or other predefined roles .

    List all parameters versions

    To list all the parameter versions associated with a parameter, use one of the following methods:

    Global parameters

    Console

    1. In the Google Cloud console, go to the Secret Manager page.

      Go to Secret Manager

    2. Click Parameter Manager to go to the Parameter Manager page. You'll see the list of parameters for that project.

    3. Click the parameter name to view its versions.

      The parameter details page opens with the Versions tab in focus where you can see all the versions of the selected parameter.

    gcloud

    Before using any of the command data below, make the following replacements:

    • PARAMETER_ID : the name of the parameter

    Execute the following command:

    Linux, macOS, or Cloud Shell

    gcloud  
parametermanager  
parameters  
versions  
list  
--parameter = 
 PARAMETER_ID 
  
--location = 
global

    Windows (PowerShell)

    gcloud  
parametermanager  
parameters  
versions  
list  
--parameter = 
 PARAMETER_ID 
  
--location =

    Windows (cmd.exe)

    gcloud  
parametermanager  
parameters  
versions  
list  
--parameter = 
 PARAMETER_ID 
  
--location =

    You should receive a response similar to the following:

    REST

    Before using any of the request data, make the following replacements:

    • PROJECT_ID : the Google Cloud project ID
    • PARAMETER_ID : the name of the parameter

    HTTP method and URL:

    GET https://parametermanager.googleapis.com/v1/projects/ PROJECT_ID 
/locations/global/parameters/ PARAMETER_ID 
/versions

    Request JSON body:

    {}

    To send your request, choose one of these options:

    curl

    Save the request body in a file named request.json , and execute the following command:

    curl -X GET \
    -H "Authorization: Bearer $(gcloud auth print-access-token)" \
    -H "Content-Type: application/json; charset=utf-8" \
    -d @request.json \
    "https://parametermanager.googleapis.com/v1/projects/ PROJECT_ID 
/locations/global/parameters/ PARAMETER_ID

    PowerShell

    Save the request body in a file named request.json , and execute the following command:

    $cred = gcloud auth print-access-token
    $headers = @{ "Authorization" = "Bearer $cred" }

    Invoke-WebRequest `
    -Method GET `
