How to send messages/sms without Twilio phone number

Question

I tried to send a message without a Twilio phone number because we has no intent to get any messages from users. I followed this tutorial written in Ruby https://www.twilio.com/blog/send-sms-without-phone-number-ruby. I search for any similar tutorial written in PHP but to no avail.

Code:

public function sendSms(string $message, string $phone)
    {
        $sid = env("TWILIO_ACCOUNT_SID");
        $token = env("TWILIO_AUTH_TOKEN");
        $messagingSid = env("MESSAGING_SERVICE_SID");
        $twilio = new Client($sid, $token);

        $message = $twilio->messages->create(
            $phone,
            [
                "body" => $message,
                "messaging_service_sid" => $messagingSid,
            ]
        );

        return $message->sid;
    }

When this code run, an error occurred saying [HTTP 400] Unable to create record: A 'From' phone number is required I just send messages without expecting them to reply back. How can I do it? Or Do I need to buy one for it to work?

Answer 1

It seems to me that you supply an unknown parameter to the function call. According to this docs page, it should be messagingServiceSid instead of messaging_service_sid.

So you could should be:

public function sendSms(string $message, string $phone)
    {
        $sid = env("TWILIO_ACCOUNT_SID");
        $token = env("TWILIO_AUTH_TOKEN");
        $messagingSid = env("MESSAGING_SERVICE_SID");
        $twilio = new Client($sid, $token);

        $message = $twilio->messages->create(
            $phone,
            [
                "body" => $message,
                "messagingServiceSid" => $messagingSid,
            ]
        )


        return $message->sid;
    }
