Reauthenticate Visual Studio Code Access Tokens

This post has been republished via RSS; it originally appeared at: New blog articles in Microsoft Community Hub.

If you've used the Azure Logic App (Standard) extension for Visual Studio Code, you are probably well aware that it uses seven-day access tokens to authenticate with Azure API Connections. This is to make up for Visual Studio Code using your work account for authentication instead of a Managed Identity you can create an access policy for.

 

The down-side to this is that currently there is no way to reauthenticate these tokens from VS Code, you generally have to create a new connection.

 

However, there is an API you can use to manually generate new access tokens:

 

POST https://management.azure.com/subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.Web/connections/{connectionName}/listConnectionKeys?api-version=2018-07-01-preview

 

The Request Body should include the following JSON:

 

{"validityTimeSpan" : "7"}

 

If we plug this into a tool like Postman, it should generate a new token that you can use to replace the existing one in local.settings.json

Update local.settings.json:

Of course, this is still tedious to have to do but luckily it is something that can be easily scripted.

 

For example, here is how you could make this request via PowerShell:

$resourceID = "/subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.Web/connections/{connectionName}" $accessToken = (Get-AzAccessToken).Token $header = @{ "authorization" = "Bearer $accessToken" "Content-Type" = "application/json" } $body = @{"validityTimeSpan" = "7"} $json = $body | ConvertTo-Json $url = "https://management.azure.com$($resourceId)listConnectionKeys?api-version=2018-07-01-preview" (Invoke-RestMethod -Uri $url -Method "Post" -Headers $header -Body $json).connectionKey

 

When scripting, you have a couple options on how to run all your existing connections through the API.

 

  1. You can get the Resource IDs from a connections.json file

  1. Use PowerShell or Azure CLI to fetch all API Connections in a Resource Group
Get-AzResource -ResourceGroupName {resourceGroupName} -ResourceType 'Microsoft.Web/connections'

 

Once you have a list of Resource IDs, you can iterate through them, putting each through the API.

 

Disclaimer: This API is currently undocumented. While it should not cause any harm, please do not use if you are not comfortable with it being undocumented.
