Send HTTP request to graph.

[JodokSenften]

Hello

I'm trying to Invite Guest Users with Power Automate with the "Send an HTTP request (Preview)" connector. 

My Flow looks like this: 

If I try this, i get an error code 400

 "message": "URI path is not a valid Graph endpoint, path is neither absolute nor relative or resource is not one of the supported (me, users, groups, sites, search, planner, teams, chats): https://graph.microsoft.com/v1.0/invitations",

Is this just no supported, am i doing something wrong or is it a bug?

Because in the docs are no restrictions listed.

https://docs.microsoft.com/de-de/connectors/office365groups/#send-an-http-request-(preview)

An if I try it with the Graph Explorer it works

Anyone may help or have some ideas? Thanks.

Hi @JodokSenften,

As far as I am aware invitation is a resource type which is not supported by this specific Office 365 Groups action.

Like the error message suggests, only me, users, groups, sites, search, planner, teams & chats resources are supported.

As a workaround you could use the HTTP action (which is premium):

Hi @JodokSenften 

Please, try to use HTTP connector (although it's premium).

Hm, i guessed this would be the case 😞 
Then I'll have to use the premium http action.

You could also try to ad a / at the end of the URL if you try to use the preview version.

I found that here: https://powerusers.microsoft.com/t5/Building-Flows/Power-Automate-O365-Groups-activities-Get-group-I...

Hi @okeks,

As far as I understood that workaround was to escape the ? character of the $filter query parameter. In this setup we are not using such a ?$filter in the URI path.

Hi @okeks,

unfortunately it doesn't help - I've already tried 😉
