I have programmed several slash commands that show a response in public channels without any problems, but they don't show any response in private channels or direct messages.
As shown below, I am using the in_channel response type. Is there any other response type I can use or a workaround so that it works everywhere?
$data = array(
"username" => "My_user",
"channel" => $channel_id,
"response_type" => "in_channel",
"text" => $text,
"mrkdwn" => true,
"icon_url" => $icon_url
);
$json_string = json_encode($data);
$slack_call = curl_init($slack_webhook_url);
curl_setopt($slack_call, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($slack_call, CURLOPT_POSTFIELDS, $json_string);
curl_setopt($slack_call, CURLOPT_CRLF, true);
curl_setopt($slack_call, CURLOPT_RETURNTRANSFER, true);
curl_setopt($slack_call, CURLOPT_HTTPHEADER, array(
"Content-Type: application/json",
"Content-Length: " . strlen($json_string))
);
$result = curl_exec($slack_call);
curl_close($slack_call);
Thanks in advance!
