API available parameters

1

For example “sales-invoice-form”，Where can I find its available parameters

$add = array(
“customer” => “”,
“issueDate” => “”,
“reference” => “”,
“description” => “this Order Description”,
“Lines” => array(
array(
“lineDescription” => “this lineDescription”,
“UnitPrice” => array(“value”=>“11.01”,“currency”=>“”),
“qty” => 10
)
),
“lineDescription” => true
)

I need help, thank you!
