I've created a custom app using Shopify CLI and have my app embedded in Shopify POS.
When I try to add or remove customers to cart, it's not sending a POST request to the promotions endpoint any more. (I remember it was sending well before). I followed all steps according to the doc.
I attached the extension setting of my app. All endpoints are correct (tested via Postman)
I can't find any helpful document and forums.
I contact the partner support team and the support person said that he is new to this and so can't help.
I found this which is very complaining.
What am i wrong? Any advise, very thank you!
For future notes, turns out each time you restart the server you need to re-save /manage_extensions/point_of_sale/pos_cart_promotion settings as the ngrok URL is changed, shouldn't be a problem if you have a fixed URL.
Now, it's working.
I got the same issue, I tried to add/remove customers but never get any request from Shopify, no request at all in the server log. I'm using Android Shopify POS. Could you help to check?
