WooCommerce Product ACF not updating

I am able to populate a custom field called _affiliate_link in the default post type using:

$.ajax({
    url: wpApiSettings.root + 'wp/v2/posts',
    method: 'POST',
    beforeSend: function (xhr) {
        xhr.setRequestHeader('X-WP-Nonce', wpApiSettings.nonce);
    },
    data: {
        'title': 'New Post Title',
        'fields': {
            '_affiliate_link': 'testing-123'
        }
    }
}).done(function (response) {
    console.log(response);
});

But, I cannot update the same custom field for Products:

$.ajax({
    url: wpApiSettings.root + 'wc/v3/products?consumer_key=ck_removed_for_post&consumer_secret=cs_remove_for_post',
    method: 'POST',
    beforeSend: function (xhr) {
        xhr.setRequestHeader('X-WP-Nonce', wpApiSettings.nonce);
    },
    data: {
        'name': 'New Post Title',
        'fields': {
            '_affiliate_link': 'testing-123'
        }
    }
}).done(function (response) {
    console.log(response);
});

I get this in the response:

acf:
_affiliate_link: null

Am I missing anything to update a custom field for a product?
