## GET /concepts/suggest/{GUID}

### Description
Suggest concepts for a specific content item, based on its metadata.

### Method
GET

### Endpoint
/concepts/suggest/{GUID}

### Parameters
#### Path Parameters
- **GUID** (string) - Required - GUID of content item

#### Query Parameters
- **fields** (string) - Optional - Comma separated list of data fields to use as basis of suggestion. Default is "title". "description" and any other field defined in the /content/filters endpoint are accepted.
- **useconcepts** (boolean) - Optional - Use existing concepts already tagged to item as basis for suggestion. Ignores any values passed in the fields parameter if set to "true"

### Generate HMAC-SHA256 Hash for EdGate API Authentication (PHP)

Source: https://edgate.com/api/docs/authentication

This PHP script demonstrates how to generate the HMAC-SHA256 hash required for authenticating requests to the EdGate API. It includes steps for obtaining a timestamp, constructing the parameter string, generating the hash using the private key, and setting the 'X-Hash' header for a cURL request. Ensure you replace 'example' and the private key with your actual credentials.

```php
<?php

//public and private keys

$publicKey = 'example';

$privateKey = '6a3c8fb1062285ee69d111ca77e6f72957e55dfa0e3ac277a5a5ef82c7ba6208';

//get current UNIX timestamp

$stamp = time();

//build parameter string, adding publicKey and timestamp

$parameters = "publicKey=".$publicKey."&timestamp=".$stamp."&param1=value1";

//generate HMAC hash of parameters

$hash = hash_hmac('sha256', $parameters, $privateKey);

//set header array for CURL, including X-Hash header

$headers = array(

    'X-Hash: '.$hash

);

//this example is a GET request, if POST/PUT/DELETE, parameters string would be set as the //request body

//set CURL options

$ch = curl_init('http://api.edgate.com/profile/?'.$parameters);

curl_setopt($ch,CURLOPT_HTTPHEADER,$headers);

curl_setopt($ch,CURLOPT_RETURNTRANSFER,true);

//make request

$result = curl_exec($ch);

//close connection

curl_close($ch);

//decode response

$response = json_decode($result);
