Hi Harish, thanks for your help!

This is the snipet that I have active:

add_filter('mc4wp_integration_woocommerce_data', function ($data, $order_id) {
$order = wc_get_order($order_id);

// this sends the billing_phone field from WooCommerce to a Mailchimp field called "PHONE".
$data['PHONE'] = $order->get_meta('billing_phone', true);

// this sends the billing_wooccm18 field from WooCommerce to a Mailchimp field called "NACIMIENTO".
$data['NACIMIENTO'] = $order->get_meta('billing_wooccm18', true);

return $data;

}, 10, 2);

And this is how I have the tags in the Mailchimp audience: https://ibb.co/C2Br8mf

I had already applied the action of the “renew mailchimp audiences” button even more than 24 hours ago, but it does not seem to have any effect, the fields are still empty in my mailchimp audience list.

In the previous message, I had already sent the print of the field names of the Mailchimp fields, in the link: https://ibb.co/C2Br8mf

Hi @hchouhan

I have tried with my email and other different emails, none of them work.

In the “MC4WP > Form > Settings” options I have activated the “Update existing subscribers” option: https://ibb.co/mNL9XVB

However, remember that what I am trying to synchronize is the checkout registration data, not the newsletter form.

Hi @lapzor, thank you,

Yes, I have the “Update existing subscribers” option activated

I just tested it with a simple text field, and then I also refreshed the Mailchimp list. I still don’t see the change in Mailchimp’s audience, however I understand that it may take a couple of hours for the process to complete, I will wait 24 hours and write again with the result.

We don’t know what could be happening, the audience continues to receive data from Woocommerce even in the last few minutes, but the fields “Phone number”, “Fecha de Nacimiento”, even “Cédula” which is a simple text field are not synchronized.
