Why aren't stickers sent?

Question

PHP

Stickers are not sent by the message.sent method.
Code:
$user_att = $data->object->attachments[0]->type;
if ($user_att == "sticker") {
$sticker_id = $data->object->attachments[0]->$user_att->id;
$request_params = array(
'message' => "gg" ,
'user_id' => 6738827,
'sticker_id' => $sticker_id,
'access_token' => token here,
'v' => '5.65'
);
$get_params = http_build_query($request_params);
file_get_contents(' https://api.vk.com/method/messages.send? '. $get_params);
}
There are no errors, the method succeeds, an ellipsis (...) is sent instead of a sticker. What's
the problem ?
Thanks in advance!

Answer 1

On behalf of the group? They were not bought from the creator of the token, so they do not send them.
You can buy the necessary stickers on the page of the administrator who created the token.
