Run an Azure Pipeline through API - powershell

Question

I have done something to queue/build my pipelines in Azure through API. Now I am in need to run my pipelines through API. Hereby I attached my code for building/queuing pipeline.
$body = '
{
"definition": {
"id": 1
}
}
'
write-host "`n"
$bodyJson=$body
write-host $bodyJson -ForegroundColor Cyan
Write-Output $bodyJson | ConvertFrom-JSON
write-output $bodyJson
$bodyString=$bodyJson | ConvertTo-Json
write-host $bodyString -foregroundcolor green
$user="name"
$personalToken = "token"
$base64AuthInfo = [Convert]::ToBase64String([Text.Encoding]::ASCII.GetBytes(":$($personaltoken)"))
$Uri = "https://dev.azure.com/demoworldDemoworld/talentstogether/_apis/build/builds?api-version=5.1"
$buildresponse = Invoke-RestMethod -Method Post -UseDefaultCredentials -ContentType application/json -Uri $Uri -Body $bodyJson -Headers #{Authorization=("Basic {0}" -f $base64AuthInfo)}
write-host $buildresponse
Kindly help me to run my pipelines through API in a similar way.

Please try the following script:
Param(
[string]$orgurl = "https://dev.azure.com/{organization}",
[string]$projectName = "0508-t",
[string]$BuildDefinitionId = "166",
[string]$user = "",
[string]$token = "PAT"
)
# Base64-encodes the Personal Access Token (PAT) appropriately
$base64AuthInfo = [Convert]::ToBase64String([Text.Encoding]::ASCII.GetBytes(("{0}:{1}" -f $user,$token)))
function CreateJsonBody
{
$value = #"
{
"definition": {
"id": $BuildDefinitionId
}
}
"#
return $value
}
$json = CreateJsonBody
$uri = "$($orgurl)/$($projectName)/_apis/build/builds?api-version=5.1"
$buildresponse = Invoke-RestMethod -Uri $uri -Method Post -Body $json -ContentType "application/json" -Headers #{Authorization=("Basic {0}" -f $base64AuthInfo)}
Write-Host $buildresponse
