Sending JSON to Slack in a HTTP POST request

Question

I\'m trying to send a message using Slack\'s chat.postMessage API call. I have no problems encoding my test messages within HTTP GET, but I\'m trying to achieve the same res

Answer 1

I did this in powershell and it works like a charm.

$url="https://slack.com/api/chat.postMessage"
    $messageContent= # your message here
    $token = # your token here
    $channel = # channel name
    $opt_username= # optional user name

    $body = @{token=$token;channel=$channel;username=$opt_username;text=$messageContent;pretty=1}

    try
    {
        Invoke-WebRequest -Uri $url -Method POST -Body $body
    }
    catch
    {
        Write-Host "StatusCode:" $_.Exception.Response.StatusCode.value__ 
        Write-Host "StatusDescription:" $_.Exception.Response.StatusDescription        
    }
