Change Slack Bot Icon from Post PHP-CodePudding

We post a message to a slack channel every time a customer does a specific task. We want to change the bot Icon based on what is being posted in the channel.

Is this possible?

public static function send_to_slack($message,$title = null){

    $body = array();
    $body['text'] = '';
    $body['icon_url'] = '';
    if(!empty($title)) $body['text'] .= "*$title*\n";
    $body['text'] .= $message;

    $iconURL = "https://img.icons8.com/emoji/96/000000/penguin--v2.png";

    $body['icon_url'] .= $iconURL;

    $json = json_encode($body);
    
    //Test Slack Channel
    $slack = "SLACKURL"

    $response = wp_remote_post( $slack, array(
        'method' => 'POST',
        'body' => $json,
        )
    );

    if ( is_wp_error( $response ) ) {
        return true;
    } else {
        return true;
    }

}

CodePudding user response：

From Slack: You cannot override the default channel (chosen by the user who installed your app), username, or icon when you're using Incoming Webhooks to post messages. Instead, these values will always inherit from the associated Slack app configuration.

Found the correct way. Make sure you enable chat:write.customize in Slack oAuth Scope.

 public static function send_to_slack($message,$title = null){

    $ch = curl_init("https://slack.com/api/chat.postMessage");
    $data = http_build_query([
        "token" => "BOT-TOKEN",
        "channel" => "CHANNELID", //"#mychannel",
        "text" => $message, //"Hello, Foo-Bar channel message.",
        "username" => "MySlackBot",
        "icon_url" => $iconURL
    ]);
    curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'POST');
    curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    $result = curl_exec($ch);
    curl_close($ch);

    return $result;
