Hi @SOHRAB SHAIKH (EXTERNAL)

as specified here: https://learn.microsoft.com/en-us/azure/azure-functions/functions-bindings-storage-blob-trigger?tabs=in-process%2Cextensionv5&pivots=programming-language-csharp#filter-on-file-type

you can specify the path in here:

whenever I upload a file to my container called "documents", only files with extension "json" will trigger the azure function
