I'm having trouble in creating a WhatsApp Message template, using the WhatsApp Business API.

I already can send messages, delete template, etc.

Creating the message template is the only API implementation where I'm having some dificulties. This is the code that I'm using to create a template:

public static function CreateTemplate($templateName, $templateCat, $language, $components){     $businessaccountid = .....;     $token = ....;     $ch = curl_init();     $url = 'https://graph.facebook.com/v16.0/' . $businessaccountid . '/message_templates?allow_category_change=true&name=' . $templateName . '&category=' . $templateCat . '&language=' . $language . '&components=' . $components;     //echo($url);     //curl_setopt($ch, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_1_1);     //curl_setopt($ch, CURLOPT_VERBOSE , TRUE);     curl_setopt($ch, CURLOPT_URL, $url);     curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);     curl_setopt($ch, CURLOPT_POST, 1);     $headers = array();          $headers[] = 'Authorization: Bearer ' . $token ;     curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);               $result = curl_exec($ch);          if ($result === false) {         $result = curl_error($ch) . " - ".curl_errno($ch);              }else{         $resultDecode = json_decode($result);         if($resultDecode!=null){             $result = $resultDecode;         }         return($result);     }     curl_close($ch);      }

And this is the content of the $url variable that is being used:

"https://graph.facebook.com/v16.0/....../message_templates?allow_category_change=true&name=compra_terminada&category=MARKETING&language=pt_PT&components=[{"type":"BODY","text":"Obrigado por comprar na nossa loja. Assim que o objecto for expedido, irá receber no seu email o numero de rastreamento da encomenda."},{"type":"FOOTER","text":"A minha empresa"}]"

And this is error that it's returning from curl_error and curl_errno:

HTTP/2 stream 0 was not closed cleanly: Unknown error code (err 5) - 92

I've already tried to use CURL_HTTP_VERSION_1_1 but with no success. The curl_exec($ch) returns a generic html page from Facebook saying:

Sorry, something went wrong. We're working on it and we'll get it fixed as soon as we can.

What do I need to change in my code to create a WhatsApp Template Message?

    This issue was solved by sending the parameters as a json string, and setting the header to "application/json"

    public static function CreateTemplate($templateName, $templateCat, $language, $components){ $businessaccountid = .....; $token = ....; $ch = curl_init(); $url = 'https://graph.facebook.com/v15.0/' . $businessaccountid . '/message_templates'; $data = array( 'allow_category_change' => true, 'name' => $templateName, 'category' => $templateCat, 'language' => $language, 'components' => $components ); $headers = array(); $headers[] = 'Authorization: Bearer ' . $token ; $headers[] = 'Content-Type:application/json' ; curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_POST, 1); curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($data)); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_HTTPHEADER, $headers); $result = curl_exec($ch); if ($result === false) { $result = curl_error($ch) . " - ".curl_errno($ch); }else{ $resultDecode = json_decode($result); if($resultDecode!=null){ $result = $resultDecode; } return($result); } curl_close($ch); }
