I was going through the blob triggers example on the Microsoft website and came across this

import azure.functions as func
import azurefunctions.extensions.bindings.blob as blob

For azure.functions, I know the api doc is at link.

For azurefunctions.extensions.bindings.blob I found no api doc. Can anyone tell where to find it?

Azure Functions

hi Dhruv Singla thanks for posting this question ))

check the official azure functions python developer guide https://learn.microsoft.com/en-us/azure/azure-functions/functions-reference-python. it covers the core concepts.

for that specific extension, its actually part of the experimental bindings. microsoft doesnt maintain separate api docs for it )) what u can do is look at the source code directly on github https://github.com/Azure/azure-functions-python-extensions/tree/dev/azurefunctions-extensions-bindings-blob/samples. yes, its not ideal, but thats where the details live for now.

sometimes u can find useful comments in the code itself that explain how things work. worth looking into if u need deeper understanding )

the blob binding behaves similarly across different languages. so if u find good examples for c# or javascript, the concepts often translate to python too. general blob binding reference https://learn.microsoft.com/en-us/azure/azure-functions/functions-bindings-storage-blob.

when working with experimental features, always test thoroughly in your environment. things might change or behave differently than u expect :))

hope this helps!

Best regards,

Alex
