<# .SYNOPSIS A universal function to interact with Azure DevOps REST API endpoints. .DESCRIPTION The `Invoke-ADOApiRequest` function allows interaction with any Azure DevOps REST API endpoint. It requires the organization, a valid authentication token, and the specific API URI. The project is optional and will only be included in the URL if specified. .PARAMETER Organization The name of the Azure DevOps organization. .PARAMETER Project The name of the Azure DevOps project (optional). .PARAMETER Token The authentication token for accessing Azure DevOps. .PARAMETER ApiUri The specific Azure DevOps REST API URI to interact with (relative to the organization or project URL). .PARAMETER Method The HTTP method to use for the request (e.g., GET, POST, PUT, DELETE). Default is "GET". .PARAMETER Body The body content to include in the HTTP request (for POST/PUT requests). .PARAMETER Headers Additional headers to include in the request. .PARAMETER ApiVersion The version of the Azure DevOps REST API to use. Default is "7.1". .PARAMETER OnlyFirstPage If enabled, the function will return only the first page of results and stop if a continuation token is present. .EXAMPLE Invoke-ADOApiRequest -Organization "my-org" -ApiUri "_apis/testplan/Plans/123/suites" -Token "my-token" This example retrieves test suites from the test plan with ID 123 in the specified organization. .EXAMPLE Invoke-ADOApiRequest -Organization "my-org" -ApiUri "_apis/projects" -Token "my-token" -OnlyFirstPage This example retrieves only the first page of projects in the specified organization. .NOTES - The function uses the Azure DevOps REST API. - An authentication token is required. - Handles pagination through continuation tokens.
