Getting 404 not found error

hello postman guys before 2-3 days everything was working properly but now it’s not working can anyone help me resolve this problem

Hi @material-architect12 . Welcome to the Postman Community.

This isn’t a Postman specific problem. It appears from your router that the path "/API/ does not exist. You have an “{API}/products” path instead, hence using "/v1/products " will return a 404 since that route doesn’t exist.
