Format of Whatsapp MTM parameters is wrong

[thiagolcks]

When trying to send a Whatsapp MTM with parameters, it returns: "Invalid paramsThe value of one or more parameters is invalid."

Expected Behavior

The message should be sent.

Current Behavior

An exception is being thrown.

Possible Solution

The way that the parameters are being added to the $returnArray in the class TemplateObject is wrong. The parameters are wrapped in an extra array.

Currently:

"template": {
    "name": "namespace:name",
    "0": {
      "parameters": ["ABC"]
     }
}

Should be:

"template": {
    "name": "namespace:name",
    "parameters": ["ABC"]
}

Steps to Reproduce (for bugs)

Just try to send any message with any parameters:

$template = new TemplateObject('namespace:name', ['ABC']);
$whatsAppText = new WhatsAppTemplate($to, $from, $template, 'pt-BR');
$client->messages()->send($whatsAppText);
