How to Add Recipient to Sendgrid v3 API with PHP - php

Question

What I'm looking to do is add a single recipient to sendgrid when they signup on my site. Once they're added, I will then email the user and add them to a list.
But I'm having trouble adding the user to Sendgrid.
Their documentation (https://sendgrid.com/docs/API_Reference/Web_API_v3/Marketing_Campaigns/contactdb.html#Add-Recipients-POST) says to add a user you need to POST their details here:
https://api.sendgrid.com/v3/contactdb/recipients
add_user_new($email);
function add_user_new($email) {
$url = 'https://api.sendgrid.com/v3/contactdb/recipients';
$params =array( array(
//'name' => 'this is a reserved field',
'email'=> 'info#domain.com'
));
$json_post_fields = json_encode($params);
// Generate curl request
$ch = curl_init($request);
$headers = array("Authorization: Bearer api_key_here");
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_TIMEOUT, 60);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
// Apply the JSON to our curl call
curl_setopt($ch, CURLOPT_POSTFIELDS, $json_post_fields);
$data = curl_exec($ch);
if (curl_errno($ch)) {
print "Error: " . curl_error($ch);
} else {
// Show me the result
var_dump($data);
curl_close($ch);
}
echo $json_post_fields;
}
This is the response I get, not sure what I'm missing. The error they say is because the JSON is invalidly formatted.
string(51) "{"errors":[{"message":"request body is invalid"}]}
This is what my JSON looks like:
{"name":"hello#test.com"}

Encode your $json_post_fields variable do in JSON format
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($json_post_fields));
