WooCommerce integration, phone number to list

The eshop only has guest checkout, so the phone number must be captured from the checkout form.

You can use custom code to send extra fields.
Here is an example:
https://github.com/ibericode/mailchimp-for-wordpress/blob/master/sample-code-snippets/integrations/woocommerce/send-billing-fields.php

Hope that helps. If you have any questions, please let me know!

Thank you so much, it worked!!

If someone else need it, im sending the code that works for billing phone. *You also need to enable PHONE in Audience fields and *|MERGE|* tags in your mailchimp audience list settings in your mailchimp account.

/**
 * This will send additional WooCommerce checkout fields to MailChimp.
 *
 * @return array
 */
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_billing_phone();


	return $data;
}, 10, 2);

Thanks for sharing! I’ve added your example to the github snippet.
