How do I automate the addition of service connection to Azure DevOps using powershell

Question

I want to add SPN to Azure DevOps Service Connection through Powershell automation

Answer 1

You can add a service connection using the powershell script that uses the REST API 'Endpoints - Create' to create service connection.

# Parameters for the script
Param(
   [string]$AZP_URL = "https://dev.azure.com/your-organization",
   [string]$AZP_PROJECT = "your-project",
   [string]$AZP_TOKEN = "your-PAT-token",
   [string]$AZP_CONNECTION = "your-service-connection-name",
   [string]$AZP_SUBSCRIPTION_ID = "your-subscription-id",
   [string]$AZP_SUBSCRIPTION_NAME = "your-subscription-name",
   [string]$AZP_TENANT_ID = "your-tenant-id",
   [string]$AZP_SP_ID = "your-service-principal-id",
   [string]$AZP_SP_KEY = "your-service-principal-secret"
)

# Base64-encode the Personal Access Token (PAT)
$base64AuthInfo = [Convert]::ToBase64String([Text.Encoding]::ASCII.GetBytes(":$AZP_TOKEN"))

# Construct the JSON body for the Azure DevOps service connection
$jsonBody = @"
{
  "data": {
    "SubscriptionId": "$AZP_SUBSCRIPTION_ID",
    "SubscriptionName": "$AZP_SUBSCRIPTION_NAME"
  },
  "name": "$AZP_CONNECTION",
  "type": "azurerm",
  "authorization": {
    "parameters": {
      "tenantid": "$AZP_TENANT_ID",
      "serviceprincipalid": "$AZP_SP_ID",
      "serviceprincipalkey": "$AZP_SP_KEY"
    },
    "scheme": "ServicePrincipal"
  },
  "isReady": true
}
"@

# Azure DevOps REST API URL for creating a service connection
$azureDevOpsServiceConnectionUrl = "$AZP_URL/$AZP_PROJECT/_apis/serviceendpoint/endpoints?api-version=5.1-preview.2"

# Make the REST API call to create the service connection in Azure DevOps
Invoke-RestMethod -Uri $azureDevOpsServiceConnectionUrl -Method POST -Body $jsonBody -ContentType "application/json" -Headers @{Authorization=("Basic {0}" -f $base64AuthInfo)}
