Hi
sampanna
The url and api are templates; you must use your app name in place of app_name. To test it, you must ensure that you have the api method and are using the correct url.
let me to summarize the issue with the 404 that arose during the webapp's deployment to the Azure app service.
Prior to anything else, we must verify if the project has view pages or webapi. Swagger UI typically vanishes when publishing to Azure, as predicted because it's mostly utilized in the development environment.
Verify the completeness of the published files by going to the wwwroot folder. Additionally, you can publish the files that function well locally. by dragging and dropping.
Kindly accept if this helps thanks much.
