Zammad API: Create ticket with tag - php

Question

For those who don't want to read the whole question:
I'm looking for the index in the API-Request (Zammad) to set a tag while creating a ticket.
Details:
I'm using PHP to make an API-Request to my server where Zammad is installed. The following shows the data i sent via curl:
json_encode([
"title" => $title,
"group_id" => 2,
"priority_id" => 2,
"category" => 'Some Category',
"state_id" => 1,
"type" => "Some Type",
"customer" => $userID,
"article" => [
"body" => $htmlBody,
"type" => "note",
"content_type" => "text/html",
],
"tag_list" => [ // <-- The question is about this segment
"The tag i want to add",
],
]);
After converting the data to JSON, im sending it via POST to http://<myServerIP>/api/v1/tickets
What I've tried so far:
I tried guessing the index of the tag at which i failed.
The first full example is shown above.
Secondly:
...
"tag_id" => 9, // I've check its the actual ID of the tag i want to add
And Finally:
...
"tag" => "The tag i want to add",
Needless to say that i didn't succeed. Sometimes i get an error id (im assuming its because the index doesn't exist [who would have thought that? :)]), sometimes i get nothing and Zammad just creates the ticket without the tag. What do i mean when i say sometimes? I refer my tries specified above.
What I've also tried:
Searching for some answer on the web. The thing that comes close to what i want is this. But i would rather create the ticket with the tag instead of making another request just to add the tag.

Answer 1

I've looked inside the code, its written in ruby. The index is 'tags' and needs to be sperated by ,.
Basicly:
json_encode([
"title" => $title,
"group_id" => 2,
"priority_id" => 2,
"category" => 'Some Category',
"state_id" => 1,
"type" => "Some Type",
"customer" => $userID,
"article" => [
"body" => $htmlBody,
"type" => "note",
"content_type" => "text/html",
],
"tags" => "tag1,tag2,tag3", // or simply "tags" => "tag1"
]);
