Hi there @haribonda !
Sorry to hear IFTTT does not currently allow you to integrate with WooCommerce in the way you envisioned.
There are possibly many ways to accomplish what you are seeking, though I understand budget is also important element to this.
You may check out one of our extensions such as AutomateWoo that allows you to set up a workflow to send SMS messages (Twilio integration).
Here is how you can set up a workflow using AutomateWoo extension: https://automatewoo.com/docs/twilio/sending-sms-from-a-workflow/ AutomateWoo also has many ways to set up workflows to send emails as well, so it would be a great tool to communicate with your customers.
You may further seek other alternative on the web by keywords such as “WooCommerce order status change SMS” etc. Here is one of the example results: https://www.pabbly.com/how-to-send-sms-when-order-status-changes-in-woocommerce/ There are also a few pluings/serveses out there that can integrate with IFTTT and WooCommerce.
You may also consider other ways around this such as integrating orders with spreadsheet applications such as Google Sheet, Airtable, etc then creating another layer of automation within the spreadsheet. (Trigger is when column changes to X, send SMS message, etc.) Though this would likely also cost you, it may be good to consider it.
I cannot go on any further on this since this is out of our support scope. I hope you find the right solution.
