How to undelete a deleted release definition?

We (Garima Srivastava) have recently added a feature in the product with which you can undelete a release definitions yourself using our rest APIs. This undelete can be done within 4 weeks of deletion and after which the definition is deleted permanently. Here is a sample power-shell script which uses our rest APIs to find the deleted definitions and then undeletes one of them.

param ( [Parameter(Mandatory=$true)] [ValidateNotNullOrEmpty()] [string] $token ) ## Construct a basic auth head using PAT function BasicAuthHeader() { param([string]$authtoken) $ba = (":{0}" -f $authtoken) $ba = [System.Text.Encoding]::UTF8.GetBytes($ba) $ba = [System.Convert]::ToBase64String($ba) $h = @{Authorization=("Basic{0}" -f $ba);ContentType="application/json"} return $h } # Fill in your account name/project name/definition name $accountName = "aseemb" $projectName = "dockerConf" $definitionNameToRecover = "New Release Definition" # Find the Id of release definition that got deleted $deletedReleaseDefinitionsUri = "https://$$projectName/_apis/Release/definitions?api-version=4.0-preview.3&isDeleted=true&searchText=$definitionNameToRecover" $h = BasicAuthHeader $token $deletedDefinitions = Invoke-RestMethod -Uri $deletedReleaseDefinitionsUri -Headers $h -ContentType “application/json" -Method Get $deletedDefinitionJSON = $deletedDefinitions | ConvertTo-Json -Depth 100 write-host "Found the deleted definitions : $deletedDefinitions" $deletedReleaseDefinitionId = $deletedDefinitions.Value[0].id write-host "Found the deleted id : $deletedReleaseDefinitionId " # Recover the deleted release definition $undeleteReason = '{ "Comment" : "Deleted by mistake" }' $undeleteReleaseDefinitionUri = "https://$$projectName/_apis/Release/definitions/$deletedReleaseDefinitionId`?api-version=4.0-preview.3" $undeletedDefinition = Invoke-RestMethod -Uri $undeleteReleaseDefinitionUri -Headers $h -ContentType “application/json" -Method Patch -Body $undeleteReason $name = $ write-host "$name recovered successfully"
