apply coupon code in the checkout page not working.

[gabriel_helle]

Hello,

applying coupon In the cart it is working properly:

http://prntscr.com/swl5ny

but if you add the code in the check-out it is not working. In the browser console I am seeing this error each time when I try to put the coupon:

jquery.js:10260 PUT https://www.123turkey.com/rest/default/V1/guest-carts/49WnoQFuZvbQxHcv3eW66xWRGbokmwPr/coupons/999of... 404 (Not Found)

I do not believe that this issue is related to the server configuration. If there was an issue with the server the coupon was not going to work in each form. Additionally, i check with the server & does not block the PUT requests .

anyone could assist and help to solve this issue.

Thanks and Regards,

Gabriel

Can you check your coupon code conditions again which is not matching as per checkout or it might be issue like below shared one:

Hello @Manish Mittal 

thanks for your kind answer,

yes you was correct, 

it was the issue with server side in the shared link which you provide.

THanks and Regards,

Yes, sometimes coupon codes don't work properly, which means they are not used or used less. If you are having issues with coupon codes not working on the checkout page of your eCommerce website, there could be several reasons for this issue. And my suggestion is to avoid fake coupon codes, Below are some steps to troubleshoot and resolve the issue:

Check coupon code details
Coupon Code Rules
Date of Expiry
Usage limit
Cart Eligibility
Customer account
Website cache
Platform updates
Test in different browsers
Message error
Contact support
Third-Party Plugins
