Hi @namrata016, if you've created two separate discount codes and you're still not seeing them apply together, you may want to check each code's "applies with" setting through the GraphQL Admin API. In order for per-product discount codes to be able to apply together at the same time, they do need to be enabled to "combine" with each other. 

Let us know if we can clarify anything further on our end - hope this helps!
