I need to create an observer or plugin or something else that will run when an order is attempted to be created through the admin. I added a custom attribute for customers (offline/online). If the attribute is set to offline then an order can not be created for the customer. Is there event that can be observed or is there a better approach?

Thanks in advance.

You can create a Plugin aroundSavePaymentInformationAndPlaceOrder. This plugin will execute on the click of Place Order before order generation on checkout Page. Remember you need to overwrite two classes GuestPaymentInformationManagement and PaymentInformationManagement.


Give a look to vendor/magento/module-sales/Controller/Adminhtml/Order/Create.php file

You'll find some events there, such as adminhtml_sales_order_create_process_data_before, adminhtml_sales_order_create_process_item_before, adminhtml_sales_order_create_process_data, etc...

Depending by which exact moment you need to run your validation you may choose one or another

Another approach: I believe you could use almost all generic order events during checkout in frontend, but just placing your events.xml file in etc/adminhtml folder in your module. This way they will run only in admin requests
