Invalid email address - php API


I'm trying to test the API by adding a subscriber.

I've copied the example from the API code on github and modified it to my requirements:

require_once 'csrest_subscribers.php';

$wrap = new CS_REST_Subscribers('XXX', 'XXX');

$result = $wrap->add(array(
    'EmailAddress' => 'Subscriber email',
    'Name' => 'Subscriber name',
    'CustomFields' => array(
            'Key' => 'name',
            'Value' => 'Test'
            'Key' => 'email',
            'Value' => ''
    'Resubscribe' => true

echo "Result of POST /api/v3/subscribers/{list id}.{format}\n<br />";
if($result->was_successful()) {
    echo "Subscribed with code ".$result->http_status_code;
} else {
    echo 'Failed with code '.$result->http_status_code."\n<br /><pre>";
    echo '</pre>';

But it gives me the following error message:

Result of POST /api/v3/subscribers/{list id}.{format}
Failed with code 400
object(stdClass)#5 (2) {
  string(37) "Please provide a valid email address."

What am I doing wrong?

Any advice appreciated.

Hi Dan,

The email address you've submitted is literally "Subscriber email". From your code:

$result = $wrap->add(array(
    'EmailAddress' => 'Subscriber email',
    'Name' => 'Subscriber name',

Name and email aren't custom fields - they're fundamental attributes of a Subscriber.

Try this:

$result = $wrap->add(array(
    'EmailAddress' => '',
    'Name' => 'Test',
    'Resubscribe' => true
