$command = DeletePayMethod;$postData = array paymethodid = 1;$adminUsername = ADMIN_USERNAME; Optional for WHMCS 72 and later$results = localAPI$command $postData $adminUsername;print_r$results;

The given code is an example of how to use the localAPI function in WHMCS to delete a payment method.

The localAPI function is a built-in function in WHMCS that allows you to perform API actions within your WHMCS installation without having to make an external API request.

In the given code, the $command variable is set to 'DeletePayMethod', indicating that we want to delete a payment method. The $postData variable is an array containing the necessary data for the API request, which in this case is the paymethodid parameter set to '1'.

The $adminUsername variable is an optional parameter that can be used in WHMCS 7.2 and later versions to specify the username of an admin user who has the necessary permissions to perform the API action. If not provided, the API request will be executed as the currently logged-in admin user.

The localAPI function is then called with the $command, $postData, and $adminUsername parameters to perform the API action. The result of the API request is stored in the $results variable.

Finally, the $results variable is printed using the print_r function to display the output of the API request
