Previously, I’ve added some code to my functions file:
// Create custom query for API
if( ! function_exists( 'product_meta_request_params' ) ) :
function product_meta_request_params( $args, $request ){
$args += array(
'meta_key' => $request['meta_key'],
'meta_value' => $request['meta_value'],
'meta_query' => $request['meta_query'] == 1 ? array(
array(
"key" => "model",
"value" => array(''),
"compare" => 'NOT IN',
)
) : $request['meta_query']
);
return $args;
}
add_filter( 'rest_product_query', 'product_meta_request_params', 99, 2 );
endif;
My API URL then looked like:
https://www.domain.com/wp-json/wp/v2/product/?page=' . $current_page . '&per_page=10&meta_query=1
