How can I get Flow to register a new user with read permissions in a sharepoint site?

[Sergio_Carol]

I am quite new to Flow and I want that after an approval process, the user has access to a sharepoint site. How can I get Flow to register this new user with read permissions? Any help will be greatly appreciated.

Hi @Sergio_Carol 

You can achieve this by couple of flow actions.

You need to use the Send an HTTP request to SharePoint flow action to get the user prinicipal id using email address.

_api/web/SiteUsers/getByEmail('useremail.com')

Next assign the read permissions for this user using Send an HTTP request to SharePoint

_api/lists/getByTitle(‘Contracts’)/items(1)/roleassignments/addroleassignment(principalid=<principalid>, ,roledefid=1073741826)

Please see this blog for more details:

Thanks for your answer.  I tried what you indicated but still giving error. Is the syntax that I use correct?

The error message is:

Hi @Sergio_Carol 

Use the single quotes for getByEmail('email.com')
