Add value to custom field when creating a product

Hello,

I’m using the rest api to add products to WooCommerce. The products have a custom field called affiliate_link (created with the acf plugin).

If I manually enter a value into this field, I can display this in the get product response – it looks like: affiliate_link: ‘the new value’

However, if I try to set the value dynamically. Nothing happens – it looks like: affiliate_link: null

PHP:

add_action('rest_api_init', 'rest_api_init_func');
function rest_api_init_func(){
	
    register_rest_field('product', 'affiliate_link',
        array(
			'get_callback' => 'the_callback_func_get',
			'update_callback' => 'the_callback_func_update',
            'schema' => null,
        )
    );
}
function the_callback_func_get($post) {
	$id = $post['id'];
	$brand_type = get_field('affiliate_link', $id );
	
		return $brand_type;

}
function the_callback_func_update($value, $post) {
	$id = $post['id'];
	update_field('group_5f48ff79c7e23',$value, $id );

}

JS:

 
apiV3.post("products", {
        ...
        fields: {
            affiliate_link: <code>${itemA.affilLink}</code>,
        }
    })

I’m using the JavaScript Rest API Library:
https://www.npmjs.com/package/@woocommerce/woocommerce-rest-api

Can anyone point me in the right direction on how to add a value to a custom field when creating a product?

You are using the field group key here

update_field('group_5f48ff79c7e23',$value, $id );

try using the field key which should look something like field_XXXXXXXX

Thanks for the response.

However, I updated the update_field to:

update_field('affiliate_link', $value ,$object->get_id());

With WooCommerce, I had to use get_id().

I can now programmatically set the custom field value.
