WHMCS CUSTOM API's Solutions

Currently WHMCS API is very limited and doesnt provide a full experience to comunicate with it.

This project consists of sharing custom API solutions:

Currently Available:

GetProductsActive
AddCreditApi
GetProductsGroups
PaymentData
AddPromoCode

Register API's in WHMCS system to be used in Role Management

Add the following hook file in /includes/hooks/ directory. Make your changes to fit your group needs.

GetProductsActive

Currently WHMCS API GetProducts api-reference/getproducts retrieves all products and no information regarding if the product is active or not.

So I just created my own API call to handle this and only retrieve the visible (not hidden) products.

Just upload to /includes/api .

Request Parameters "GetProductsActive"

Parameter	Type	Description	Required
action	string	“GetProductsActive”	Required
pid	int	Obtain a specific product id configuration. Can be a list of ids comma separated	optional
gid	int	Retrieve products in a specific group id	optional

Response Parameters

Parameter	Type	Description
result	string	The result of the operation: success or error
totalresults	int	The total number of results available
startnumber	int	The starting number for the returned results
numreturned	int	The number of results returned
products	array	An array of products matching the criteria passed

Example Request (Local API)

$command = 'GetProductsActive';
$postData = array(
    'pid' => '1', // or gid => '1' or both
);
$adminUsername = 'ADMIN_USERNAME'; // Optional for WHMCS 7.2 and later

$results = localAPI($command, $postData, $adminUsername);
print_r($results);

Example Request (CURL)

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://www.example.com/includes/api.php');
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS,
    http_build_query(
        array(
            'action' => 'GetProductsActive',
            // See https://developers.whmcs.com/api/authentication
            'username' => 'IDENTIFIER_OR_ADMIN_USERNAME',
            'password' => 'SECRET_OR_HASHED_PASSWORD',
            'pid' => '1',
            'responsetype' => 'json',
        )
    )
);
$response = curl_exec($ch);
curl_close($ch);

Example output:

    "result": "success",
    "totalresults": 1,
    "products": {
        "product": [
            {
