Create reviewers for environments in github repository

The below powershell works and helps create environment test_mont under repo variables

# Define the owner, repository, environment, token, and reviewer variables
$owner = "knowyrtech" # The name of the owner of the repository
$repo = "variables" # The name of the repository
$envName = "test_mont" # The name of the environment
$token = "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" # The authentication token for accessing the GitHub API

$uri = "https://api.github.com/repos/$owner/$repo/environments/$envName"
$header = @{"Authorization" = "token $token"}

Invoke-WebRequest -Method PUT -Header $header -ContentType $contentType -Uri $uri 

Next, Below powershell adds reviewers into the created environment which fails.

# Define the owner, repository, environment, token, and reviewer variables
$owner = "knowyrtech" # The name of the owner of the repository
$repo = "variables" # The name of the repository
$envName = "test_mont" # The name of the environment
$token = "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" # The authentication token for accessing the GitHub API

# Define the required reviewers (GitHub usernames) you want to add
$requiredReviewers = @("knowyrtech")
#$requiredReviewers = @("mybank/are-devops")

# Convert the list of reviewers to JSON format
$reviewersJson = $requiredReviewers | ForEach-Object {
    @{
        reviewer = $_
    }
} | ConvertTo-Json


# GitHub API URL for updating environment protection rules
$uri = https://api.github.com/repos/$owner/$repo/environments/$envName/reviewers

# Set headers with the authentication token
$headers = @{
    "Authorization" = "token $token"
    "Accept" = "application/vnd.github.v3+json"
}

# Send a POST request to add the required reviewers to the environment
$response = Invoke-WebRequest -Uri $uri -Method PUT -Headers $headers -Body $reviewersJson -ContentType "application/json" 

# Check the response
if ($response.StatusCode -eq 200) {
    Write-Host "Required reviewers added to the environment."
} else {
    Write-Host "Failed to add required reviewers."
}

OUTPUT:

Invoke-WebRequest : {"message":"Not Found","documentation_url":https://docs.github.com/rest}
At line:26 char:13
+ $response = Invoke-WebRequest -Uri $uri -Method PUT -Headers $headers ...

Failed to add required reviewers.

I also tried:

# Convert the list of reviewers to JSON format

$reviewersJson = $requiredReviewers | ForEach-Object {
    @{
        "reviewers" = [
            @{
                "type" = "User"
                "id" = $_
            }
        ]
    }
} | ConvertTo-Json

But getting an error:

At line:12 char:24 + "reviewers" = [ + ~ Missing type name after '['. At line:16 char:14 + } + ~ Missing '=' operator after key in hash literal. At line:10 char:54 + $reviewersJson = $requiredReviewers | ForEach-Object { + ~ Missing closing '}' in statement block or type definition. + CategoryInfo : ParserError: (:) [], ParentContainsErrorRecordException + FullyQualifiedErrorId : MissingTypename

Finally, I tried replacing "reviewers" = [ with "reviewers" : [ but that too did not work.

I also tried changing the uri to $uri = "https://api.github.com/repos/$owner/$repo/environments/$envName/protection-rules"

The environment is visible and accessible as below:

https://api.github.com/repos/knowyrtech/variables/environments/test_mont

Kindly suggest adding multiple reviewers to the environment using API calls.

Update: tried solutions by @050 but getting a series of errors:

To get the proper format you need to do something like this:

# adding multiple users
# $requiredReviewers = @{reviewers = @(@{type="User";id=111655092},@{type="User";id=123456})}

#single user
$requiredReviewers = @{reviewers = @(@{type="User";id=111655092})}

# to add a team: 'type=User' needs to be 'type=Team' and you need to 
# use the teamid
#{type="Team";id=123456}

# Convert the list of reviewers to JSON format
$reviewersJson =  ConvertTo-Json $requiredReviewers

The id is your user id so it'll be a number. I put the user id for the username that you have listed in your example. You can get the user id by replacing "usernamehere" with your username. https://api.github.com/users/usernamehere

There is also a restriction on the number of users/teams you can add "You can list up to six users or teams as reviewers"(reference).

Also the url needs to be in quotes and was wrong:

$uri = https://api.github.com/repos/$owner/$repo/environments/$envName/reviewers

Remove "/reviewers" at the end of the url and add quotes:

$uri = "https://api.github.com/repos/$owner/$repo/environments/$envName"

After making those changes I was able to successfully run the script.

Adding Teams

It's essentially the same as adding a user, except you change type="User" to type="Team". You will also need to obtain the teamid. You can do this via api call. Bellow will output your teamid. Your token will have to have correct permissions. (Reference)

$headers = @{Authorization = "token yourtoken"}
# org name
$myorg = "mybank"
# team name
$team = "are-devops"

$content = Invoke-WebRequest -Headers $headers -URI https://api.github.com/orgs/$myorg/teams/$team
$items = $content.Content | ConvertFrom-Json 

Write-Output $items.id

Alternatively, you could just go to your team page right click the avatar image and copy the address. The team id will be in the link.
