An introduction to calling Microsoft Graph within Power Automate

Microsoft Graph is the (strange and misleading) name for the gateway provided by Microsoft to get at all of the things stored in your 365 cloud (emails, files, users, groups, teams and much more). This tutorial explains what Graph is in more detail, and shows how you can call Graph from within Power Automate flows.

Accessing HTTP request results within your flow

Using one of the built-in 365 HTTP requests
Using a pre-authorised HTTP request

To get things from Graph you have a number of choices - here are 3 of them:

Action	Notes
	These let you get information from specific parts of 365, and are free to use.
	This uses Entra (previously called ActiveDirectory) as a paid service to get information from any parts of your 365 setup.
	This paid connector lets you link to any Graph service, but requires you to set up authentication first.

If you already know how to set up authentication I suspect you won't be reading this blog, so I'm going to focus on the first two options below.

Using one of the built-in 365 HTTP requests

Let's suppose that you want to see details of all of your emails. Because there's a dedicated HTTP request for this, you could use it:

Use this action to request data from Outlook using Graph.

Use Graph Explorer to find which URL to use:

I'll use this URL.

Paste this into a new flow action:

This is the URL for listing your emails.

You can now see your emails:

See the next and final part of this blog for how to turn this output into an array so that you can retrieve information from it.

Using a pre-authorised HTTP request

For a more generally applicable solution, use a pre-authorised Entra ID request:

As the caption shows, this is a premium service.

When you choose this service you'll be asked either to create a premium account or to sign up for a 90-day trial (I opted for the latter!). As mentioned above the mysteriously named Entra is just the old ActiveDirectory by a new name.

As described in the previous part of this blog, get the URL for listing the teams you're part of using Graph Explorer:

This is the one you want - paste it in as the Url of the request parameter for your HTTP request action.

You should now have this action, which you can run:

This is the URL you want to visit.

Once again, see the final part of this blog for how to turn the JSON object returned into an array so that you can list out (here) the teams you're a member of:
