unauthorized response when i do api call

[KitoodleCreators]

I successfully received the access token.

But when I try to do any API action I receive this error:

{"error_key":"unauthorized","error_message":"Unauthorized"}

I am using following code to create new contact:

<?php

$access_token = "{token removed}";

$url = 'https://api.cc.email/v3/contacts';
$postdata = '{
"email_address": {
"address": "sibinfotech101@gmail.com",
"permission_to_send": "implicit"
},
"create_source": "Account",
"custom_fields": [
{
"custom_field_id": "0123895a-35cd-11ee-a3a3-fa163eb65cb7",
"value": "Tushar"
},
{
"custom_field_id": "485b7d4a-35dd-11ee-a3a3-fa163eb65cb7",
"value": "9099887766"
},
{
"custom_field_id": "0863b528-35cd-11ee-bcfd-fa163eb65cb7",
"value": "Test Subject"
},
{
"custom_field_id": "0d7f2f92-35cd-11ee-bcfd-fa163eb65cb7",
"value": "Test Message"
}
]
}';

$ch = curl_init($url);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $postdata);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
'Cache-Control' => 'no-cache',
'Authorization' => 'Bearer '.$access_token,
'Accept' => 'application/json',
'Content-Type' => 'application/json',
));
$result = curl_exec($ch);
curl_close($ch);
print_r ($result);

exit;

?>

Please let me know what is that issue.
