Sendgrid adding to mail list not working - php

Question

I am using the following code for adding emails to a list in sendgrid. But it is returning inserted :0 response
$request_url = "https://sendgrid.com/api/newsletter/lists/email/add.json";
$data = array("email"=>"testemail#test.com");
$params = array(
'api_user' => $sengrid_user,
'api_key' => $sendgrid_pass,
'list'=>"TestAlwin",
'data' =>json_encode($data)
);
$ch = curl_init();
curl_setopt($ch,CURLOPT_URL, $request_url);
curl_setopt ($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $params);
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_VERBOSE, true);
$resp = curl_exec($ch);
curl_close($ch);
This is returning inserted :0 response. It should insert the mailid to the list I have specified.
I am using the following as reference :
curl -d 'api_user=your_sendgrid_username&api_key=your_sendgrid_password&list=my_list&data[]={"email":"address1#domain.com","name":"contactName1"}&data[]={"email":"address2#domain.com","name":"contactName2"}' https://sendgrid.com/api/newsletter/lists/email/add.json
This is actually given in their api here :
http://sendgrid.com/docs/API_Reference/Marketing_Emails_API/emails.html
and I am adding the curl vebrose here :
* About to connect() to sendgrid.com port 80 (#0)
* Trying 1.1.1.1... * connected
* Connected to sendgrid.com (1.1.1.1) port 80 (#0)
> POST /api/newsletter/lists/email/add.json?list=TestAlwin HTTP/1.1

These 1.1.1.1 is just a test IP that I have added here instead of the actual one.

Answer 1

The SendGrid Newsletter API is broken- specifically you can't add more than a single email to a list at a time, making it unusable. I reported it a week ago- they confirmed the bug, gave no timeline for a fix. They don't seem too concerned...

Answer 2

The SendGrid Newsletter API requires both 'email' and 'name' parameters at a minimum (as seen in the docs: http://sendgrid.com/docs/API_Reference/Marketing_Emails_API/emails.html)
I updated your test code to include "name" => '' to the code and it works beautifully (also fixed typo in the api_user's $sendgrid_user variable).
Cheers!
