Unavailable action with Floating IPs API

I’m using the v2 API to assign Floating IPs to different droplets. It’s working great in Postman, however i’m having some issues getting it to work in PHP with CURL. I’m not sure quite where i’m going wrong, any pointers would be greatly appreciated!


 [id] => not_found
 [message] => The specified action type is not available


     * Change where a Floating IP Points
     * @param string $floatingIp
     * @param int $dropletId
     * @return array
    public function assignFloatingIp($floatingIp, $dropletId)
        $data = array (
            'type' => 'assign',
            'droplet_id' => $dropletId

        $response = $this->makeQuery(''. $floatingIp .'/actions', 'POST', $data);

        if (!array_key_exists('action', $response)) {
            echo ucfirst($this->response['id']) . "<br>" . $this->response['message'];

        return $response;

    * Make query
    * @param string $url
    * @param string $method
    * @param array $data
    * @return array
    private function makeQuery($url, $method = 'GET', $data = null)
        try {
            $headers = array('Authorization: Bearer '.$this->token);

            $curl = curl_init($url);
            curl_setopt($curl, CURLOPT_CONNECTTIMEOUT, 30);
            curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
            curl_setopt($curl, CURLOPT_CUSTOMREQUEST, $method);

            if ($data) {
                $data = json_encode($data);

                curl_setopt($curl, CURLOPT_POSTFIELDS, $data);
                        'Content-Length: ' . strlen($data)

            curl_setopt($curl, CURLOPT_HTTPHEADER, $headers);

            //Data are stored in $data
            $response = json_decode(curl_exec($curl), true);

            return $response;
        } catch (Exception $e) {
            return $e->getMessage();

Looks like your request payload is correct from

I’ve always had trouble making requests using native curl. Perhaps give something like Guzzle a shot just to confirm the request is correct and work back from some examples? I always reference how Twilio does it
