Using Flarum api to create secondary tags

basil

I was creating a note a note sharing platform for students.I have setup Flarum for chat forum in the portal.We keeps adding details about different subjects into the platform.I also have to manually add tags for each subject inside Flarum.Could somebody help me on how to create secondary tags with the name of the subjects, under a particular primary tag using the api? Primary tags are already there.

By analyzing the requests in Chromium developer, I found the structure of request.A secondary tag can be created by following code.It seems to be difficult to reorder tags using the api since we have to reorder entire tags.
public function createTag($tagname,$slug,$description)
{
$data= [
"data" => [
"type" => "tags",
"attributes" => [
"name" =>$tagname,
"slug" => $slug,
"description" => $description,
"color" => "",
"ishidden"=>false]
]
];
$response = $this->sendPostRequest('/api/tags', $data);
var_export($response);
}
