Scheduling a Azure DevOps release using Powershell - powershell

Question

I am able to trigger a Azure DevOps release using Rest API call. But when i tried to do it by adding the scheduling it is not working. The code i used is given below:
$PATtoken= 'PAT'
$token = [System.Convert]::ToBase64String([System.Text.Encoding]::ASCII.GetBytes(":$($PATtoken)"))
$header=#{authorization= "Basic $token" }
$defurl = "https://vsrm.dev.azure.com/Orgnization/Project/_apis/release/definitions/13?api-version=5.1"
$definition = Invoke-RestMethod -Uri $defurl -Method Get -Headers $header
$triggers = '
[{
"schedule": {
"timeZoneId": "India Standard Time",
"startHours": 20,
"startMinutes": 40,
"daysToRelease": 31
}
}]'
$definition | Add-Member -NotePropertyName "triggers" -NotePropertyValue (Convertfrom-Json $triggers) -Force
$json = #($definition) | ConvertTo-Json -Depth 99
$updatedef = Invoke-RestMethod -Uri $defurl -Method Put -Body $json -ContentType "application/json" -Headers $header
Write-Host ($updatedef.triggers | ConvertTo-Json -Depth 99)
But unfortunately the scheduling or triggering is not happening.

Answer 1

You can do it in this way:
...
$definition = Invoke-RestMethod -Uri $defurl -Method Get -Headers $header
$hash = #(
#{ triggerType="schedule";
schedule = #{"daysToRelease"="31";"timeZoneId"="India Standard Time";"startHours"="20";"startMinutes"="40"}
}
)
$definition.triggers = $hash
$json = $definition | ConvertTo-Json -Depth 99
Invoke-RestMethod -Uri $defurl -Method Put -Body $json -ContnetType application/json -Headers $header

Answer 2

You should not add schedule into triggers to configure the release pipeline schedule execute.
You can use Postman as test. See below pic:
Even I have configure the schedule script in request body, the response body still has no content in the trigger.
To set the schedule, you need apply above schedule script to schedules which is nested under environment. Also, you could using Fiddler to capture the records to confirm this by configuring the schedule release from UI.
