如何使用 ultramsg 和 PHP 将 whatsapp 消息发送到多个号码

Question

I am trying to send WhatsApp message to multiple numbers by using Ultramsg.com using PHP

by reference: https://docs.ultramsg.com/api/post/messages/chat

the code is like this:

 <?php $curl = curl_init(); curl_setopt_array($curl, array( CURLOPT_URL => "https://api.ultramsg.com/instance1xxx/messages/chat", CURLOPT_RETURNTRANSFER => true, CURLOPT_ENCODING => "", CURLOPT_MAXREDIRS => 10, CURLOPT_TIMEOUT => 30, CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1, CURLOPT_CUSTOMREQUEST => "POST", CURLOPT_POSTFIELDS => "token=exxxxxxxx&to=1408XXXXXX1 @c.us,1408XXXXXX2 @c.us&body=WhatsApp API on UltraMsg.com works good&priority=10", CURLOPT_HTTPHEADER => array( "content-type: application/x-www-form-urlencoded" ), )); $response = curl_exec($curl); $err = curl_error($curl); curl_close($curl); if ($err) { echo "cURL Error #:". $err; } else { echo $response; }

but I am getting this error

"to": "Wrong 'to' format for element (1408xxxxxxx @c.us,1408xxxxxxx @c.us). 'to' format: 14155552671@c.us or 14155552671-441234567890@g.us"

I am not understanding this.

Answer 1

I think should try to remove space before @c.us
