Hey @plain-city-95899 i took reference from your provided repo and created RestApi module and it is working fine but my old endpoints are giving 404 not found so where i have to plug my RestApi module or is there any other solution available ?

Heyhey, my POC is based on the current demoshop to showcase the the new endpoints already before the next Spryker product release. You have two way of moving forward: Either update parts of your shop already to adapt to the new glue api completely (no guarantee for 100% stability by spryker) or use spryker-sdk/spryk 4.7.0 to generate a skeleton for a glue endpoint for the current structure. The first approach should actually consist already a fallback for previous endpoints
