(0) ShareShare

Hello there,

 

I have an azure function deployed called "DownloadFileFromSharepoint". It takes no input and return the base64 of a file that is in sharepoint. On Postman I can call the function, everything works ok. Now I would like to call it from power automate.

What am I doing wrong?

-----------------------------------------------------------
Some details from postman:
We use a bearer token for authentication.

These are the other header, they are all created automatically except from "x-sgf-userid"

The response is something like that:

erverything works good here.


----------------------------------------------------------------------------
Now I try to do something similar in power automate

The Token is the same one I have in postman, the Azure func url is the uri I obtain if I go on azure, on that specific function and I click on "Get Function Url":

The function is found from power automate, but I receive this error:
Error 403 - Forbidden
The web app you have attempted to reach has blocked your access



For sure I am doing something wrong with the auth in power automate, every help is appreciated.
Regards,
Alessandro
