Get file properties from Sharing link

[brainstorm13]

Hi gurus, 

I have a Sharepoint list where in each entity users add the link to the ppt file stored in a library, so we have the sharing link/url.

And next in the recurred flow I have to check file properties (Modified date). But all methods that I see (Get file properties, get file metadata etc.) require ID.

Is it possible to resolve sharing link and get file ID?

TIA

Hi @brainstorm13 ,

Do you want to get file identifier from a Sharing link?

I am afraid that it is not possible to get file properties from a Sharing link.

I have figured out the following workaround for your scenario, please take it for a reference.

In the list, besides the column for the Sharing link, add another text column, name it as “PPTName”.

In the library, add a custom single line of text column, name it as “FileName”, you may need to enter the exact file name manually later on.

Then set up the flow likes below.

Add trigger when an item is created.

In action Get files (properties only), input the following code in the Filter Query field:

FileName eq 'PPTName'

Then you could get the file’s modified time by using dynamic content Modified.

Note: When using above workaround, please remember enter the exact file name in the Library first when you upload it. Then in the list, in addition to add the sharing link, add the PPT name as well.

Best regards,

Mabel

Thank you for answering, interesting solution.

I'd rather add filename automatically. Perhaps there is a way to download web content using that sharing link to get the name of downloaded file?

Hi @brainstorm13 ,

I have tried to find out a way to get file name from the sharing link, but it seems that it is not possible to get the file name from the link.

Hi there, 

I have the exact same scenario - just wondering if you had managed to do this? I don't think it will fly for the users to have to put in the filename in our scenario

Appreciate any help!

I have the same challenge. But, when pasting a sharing link into an Outlook email, the display text is automatically replaced by the file name. So there seams to be some kind of API to at least get the file name from the sharing link?

I did a little bit of digging and it's easier than expected:

1. Encode the sharing link: https://www.base64encode.org/enc/unpadded/
2. HTTP GET https://YOUR_SHAREPOINT.sharepoint.com/_api/v2.0/shares/ + ENCODED_SHARING_LINK
3. Process returned JSON

Can you show me your screenshots? the links didn't work and I can't replicate what you are suggesting.
