Slack API not accepting \n for new line when using slash commands

Question

I've built a simple slack integration (slash command) to return names from my table. The result should look like

Name1

Name2

Name3

For this i simply generate a text string like this:

foreach($names as $name) {
    $text .= $name . ' \n';
}

The integration itself is working fine, however the result looks like this

Name1 \nName2\n

Answer 1

Looks like this is an issue in slack.

Apparently it can be solved by using double quotes as such: "\n".

Your code will become:

foreach($names as $name) {
    $text .= $name . "\n";
}
