Extending the woocommerce rest api


Staff member
I would like to extend the woocommerce rest api to include data of its 'booking' extension plugin. Currently this extension does not have default endpoints provided by the rest api.

So far I have created a plugin, and I've added the following code;

add_filter( 'woocommerce_rest_prepare_product', 'custom_data');

function custom_data($response, $object) {
        if( empty( $response->data ) )
            return $response;

        $response->data['meta_data'] = get_post_meta( $object[ID], 'availability', true);
        return $response;

When I call the end point
only the default data outlined by woocommerce is still called my little add on is no where to be found.

I don't even know where to find the above filter as I just saw this posted on a webpage and I tried to get it to do what I wanted, don't know if this is the correct direction to go down either. Webpage: <a href="https://francescocarlucci.com/woocommerce/woocommerce-api-custom-data-default-endpoints/#more-96" rel="nofollow noreferrer">https://francescocarlucci.com/woocommerce/woocommerce-api-custom-data-default-endpoints/#more-96</a>

The above was me trying to extend the api but I also decided to try making a custom endpoint to see if I can get my desired outcome but so far I've just made a endpoint which calls but I have no idea what to write to retrieve the data I want.

custom end point code:

function register_custom_route() {
            register_rest_route( 'ce/v1', '/bookable',
                    'methods' =&gt; 'GET',
                    'callback' =&gt; 'get_bookable'

        function get_bookable( ) {
            return array( 'custom' =&gt; 'woocommerce here' );
//What code do I write here :(


Is there anyway I can achieve what I want under one of the above methods?
I'm quite new to dev and I'm familiar with javascript not PHP hence my need to want to use the rest api as I would like to use wordpress/woocommerce as a headless cms.

So far the closets example I've come to has been shown on this question <a href="https://stackoverflow.com/questions...tom-api?noredirect=1#comment95583817_53626874">Creating WooCommerce Custom API</a>
