I've tried many variations of this but cannot seem to be able to add existing tags to an existing product via the api.
I'm currently trying:
$myTagPut = ['tags' => ['id' => 216], ['id' => 222]];
$woocommerce->put('products/'.$prod->id, $myTagPut);
There are no errors of any kind when this runs, but it also isn't adding the tags to the product.
Any help would be much appreciated.
I've also tried just a comma separated list of tag ids, adding all of the tag information (i.e. name, etc.) in the call and nothing seems to work.
