Thank you for your bootstrap.

Hello Bhaiya,
Since order.updated is triggered whenever the status changes, your code is an attractive solution to get the specific status.
This is actually what I am looking for 😄
Thank you.

Hey im not sure if you can help? i have been scouring the internet for hours and hours and im not getting anywhere. I dont know php.

I am using the woocommerce rest api on my node server to listen to webhooks - product, order, customer but it doesnt have any webhook topics for reviews.

How do I add topics or actions for reviews (crud) so that in the woocommerce api i can register webhooks with these topics and receive updates?

Any direction or help would be greatly appreciated, im at an end here :(

@Niloys7
I am glad to hear that someone else needs this code. :)

I searched and found a plugin WP Webhooks . This plugin is very costly. Did you check this? If this plugin is unable to solve your problem, you have to write custom code.

Can you tell me if the payload from your custom order complete webhook is the same as the core order created webhook? Thank you

I asked chatgpt
can you tell me if the custom woocommerce webhook shown here creates the same payload as the built in "order created" webhook? and it said:

To determine if the custom WooCommerce webhook creates the same payload as the built-in "order created" webhook, we need to compare the payload structures and data they send.

Here's the built-in "order created" webhook payload structure:

{
  "id": 123,
  "parent_id": 0,
  "status": "processing",
  "order_key": "wc_order_1234567890abcdef",
  "number": "123",
  "currency": "USD",
  "version": "5.1.0",
  "prices_include_tax": false,
  "date_created": "2021-04-06T13:17:50",
  "date_created_gmt": "2021-04-06T17:17:50",
  "date_modified": "2021-04-06T13:17:50",
  "date_modified_gmt": "2021-04-06T17:17:50",
  "discount_total": "0.00",
  "discount_tax": "0.00",
  "shipping_total": "10.00",
  "shipping_tax": "0.00",
  "cart_tax": "0.00",
  "total": "60.00",
  "total_tax": "0.00",
  "customer_id": 2,
  "order_currency": "USD",
  "meta_data": [],
  "line_items": [],
  "tax_lines": [],
  "shipping_lines": [],
  "fee_lines": [],
  "coupon_lines": [],
  "refunds": [],
  "payment_method": "bacs",
  "payment_method_title": "Direct Bank Transfer",
  "transaction_id": "",
  "customer_ip_address": "127.0.0.1",
  "customer_user_agent": "Mozilla/5.0",
  "created_via": "checkout",
  "customer_note": "",
  "date_completed": null,
  "date_paid": null,
  "cart_hash": "",
  "number": "123",
  "meta_data": [],
  "_links": {
    "self": [],
    "collection": []
  }
}

Now let's look at the custom webhook code from the provided link:

<?php
add_action( 'woocommerce_thankyou', 'custom_order_created_webhook', 10, 1 );
function custom_order_created_webhook( $order_id ) {
    $order = wc_get_order( $order_id );

    $webhook_payload = array(
        'id' => $order->get_id(),
        'parent_id' => $order->get_parent_id(),
        'status' => $order->get_status(),
        'order_key' => $order->get_order_key(),
        'currency' => $order->get_currency(),
        'version' => $order->get_version(),
        'prices_include_tax' => $order->get_prices_include_tax(),
        'date_created' => $order->get_date_created()->date('Y-m-d\TH:i:s'),
        'date_created_gmt' => $order->get_date_created()->date('Y-m-d\TH:i:s\Z'),
        'date_modified' => $order->get_date_modified()->date('Y-m-d\TH:i:s'),
        'date_modified_gmt' => $order->get_date_modified()->date('Y-m-d\TH:i:s\Z'),
        'discount_total' => $order->get_discount_total(),
        'discount_tax' => $order->get_discount_tax(),
        'shipping_total' => $order->get_shipping_total(),
        'shipping_tax' => $order->get_shipping_tax(),
        'cart_tax' => $order->get_cart_tax(),
        'total' => $order->get_total(),
        'total_tax' => $order->get_total_tax(),
        'customer_id' => $order->get_customer_id(),
        'order_currency' => $order->get_currency(),
        'payment_method' => $order->get_payment_method(),
        'payment_method_title' => $order->get_payment_method_title(),
        'transaction_id' => $order->get_transaction_id(),
        'customer_ip_address' => $order->get_customer_ip_address(),
        'customer_user_agent' => $order->get_customer_user_agent(),
        'created_via' => $order->get_created_via(),
        'customer_note' => $order->get_customer_note(),
        'date_completed' => $order->get_date_completed() ? $order->get_date_completed()->date('Y-m-d\TH:i:s') : null,
        'date_paid' => $order->get_date_paid() ? $order->get_date_paid()->date('Y-m-d\TH:i:s') : null,
        'cart_hash' => $order->get_cart_hash(),
        'line_items' => array(),
        'tax_lines' => array(),
        'shipping_lines' => array(),
        'fee_lines' => array(),
        'coupon_lines' => array(),
        'refunds' => array()
    );

    $webhook_url = 'https://example.com/webhook';
    $response = wp_remote_post( $webhook_url, array(
        'method' => 'POST',
        'body' => json_encode( $webhook_payload ),
        'headers' => array(
            'Content-Type' => 'application/json'
        )
    ));
}
?>

The custom webhook payload is constructed using data from the WooCommerce order object, similar to the built-in webhook. However, a few differences exist:

1. Field Differences:

   • The custom webhook includes 'number' within 'webhook_payload'.
   • The built-in webhook includes '_links' which is missing from the custom webhook.

2. Data Formatting:

   • Dates in the custom webhook are formatted explicitly using the date('Y-m-d\TH:i:s') format, ensuring proper datetime formatting.

3. Empty Arrays:

   • 'meta_data' in the built-in webhook is an empty array, but the custom webhook does not include it in 'webhook_payload'.
   • 'line_items', 'tax_lines', 'shipping_lines', 'fee_lines', 'coupon_lines', and 'refunds' are included as empty arrays in the custom webhook. In contrast, these fields are included as empty arrays in the built-in webhook if there is no data.

To summarize, while the custom webhook is similar in structure to the built-in "order created" webhook, there are slight differences in fields and data formatting. Specifically, the custom webhook is missing the '_links' field and includes the 'number' field twice. Other fields such as 'meta_data' and arrays like 'line_items', 'tax_lines', etc., are included but empty.

For complete parity, you would need to ensure all fields match exactly, including the '_links' field and ensure no duplicate fields are present.

So I really don't know what that means, and I don't know if I can use it instead of Order Created ?
