I thought I had blogged about this in the past but I am mistaken.<\/p>\n

I see the following HTTP related connectors in Power Automate.<\/p>\n

\"\"\"\"<\/p>\n

Which of these can I use to say talk to Graph API authenticated (i.e. without having to fetch a token first via a regular HTTP request)?<\/p>\n

Am going to ignore the LMS one for now as I don’t know what that is (bad idea: don’t ignore things coz you don’t know what they are… but I am going to do that now anyways<\/em>).<\/p>\n

Send an HTTP request to SharePoint<\/h3>\n

I know this isn’t going to help me but I’d like to point it out. This connector can be used to make REST API calls against SharePoint<\/a>.<\/p>\n

\"\"<\/p>\n

I have a colleague who uses this extensively to do various SharePoint stuff. I haven’t bothered so far; I just use Graph or PnP.PowerShell for this. This page looks like a good starting point with some examples<\/a>.<\/p>\n

Send an HTTP Request (Outlook)<\/h3>\n

Can I do a simple Graph query with it?<\/p>\n

\"\"<\/p>\n

 <\/p>\n

Nope! I get the following error:<\/p>\n

URI path is not a valid Graph endpoint, path is neither absolute nor relative or resource\/object is not supported for this connector. Resources: me,users Objects: messages,mailFolders,events,calendar,calendars,outlook,inferenceClassification. Uri: https:\/\/graph.micrsosoft.com\/v1.0\/me<\/p><\/blockquote>\n

So it’s for a limited set of objects only – like messages<\/code> for instance. Modifying the URL to https:\/\/graph.microsoft.com\/v1.0\/me\/messages<\/code> works.<\/p>\n

Send an HTTP Request (Users)<\/h3>\n

Same error:<\/p>\n

URI path is not a valid Graph endpoint, path is neither absolute nor relative or resource\/object is not supported for this connector. Resources: me,users Objects: messages,mailFolders,events,calendar,calendars,outlook,inferenceClassification. Uri: https:\/\/graph.microsoft.com\/v1.0\/me<\/p><\/blockquote>\n

I thought I’d get a different error message, or at least the \/me<\/code> endpoint would succeed – this one’s for users after all. I know my future self reading this blog post wouldn’t trust me, so here’s a screenshot too – I didn’t select the wrong connector by mistake. :)<\/p>\n

\"\"<\/p>\n

Send an HTTP Request (Groups)<\/h3>\n

There seem to be two of these. Am going to go with the V2.<\/p>\n

\"\"<\/p>\n

Hmm:<\/p>\n

URI path is not a valid Graph endpoint, path is neither absolute nor relative or resource\/object is not supported for this connector. Resources: groups. Uri: https:\/\/graph.microsoft.com\/v1.0\/me<\/p><\/blockquote>\n

Ok what about the non-V2? Ooh, that worked! Finally.<\/p>\n

Let’s try a different query? Like say \/me\/calendar\/events<\/code>. I want to get an error to see what is allowed.<\/p>\n

Bugger, that worked too. Ok what about Teams presence? \/me\/presence<\/code>.<\/p>\n

Finally it failed. But with a different error to what I was expecting:<\/p>\n

{\r\n\t\"error\": {\r\n\t\t\"code\": \"Forbidden\",\r\n\t\t\"message\": \"\",\r\n\t\t\"innerError\": {\r\n\t\t\t\"request-id\": \"6007b16a-63fe-4a22-afe4-7e91e8ab2fc5\",\r\n\t\t\t\"date\": \"2022-10-30T13:46:23\",\r\n\t\t\t\"client-request-id\": \"6007b16a-63fe-4a22-afe4-7e91e8ab2fc5\"\r\n\t\t}\r\n\t}\r\n}<\/pre>\n
Moving on… (but note to myself, this connector is worth keeping in mind for the future. “Send an HTTP Request” (groups)<\/em>)<\/p>\n
Send an HTTP Request (Groups Mail)<\/h3>\n
Again, an error:<\/p>\n
URI path is not a valid Graph endpoint, path is neither absolute nor relative or resource\/object is not supported for this connector. Resources: groups Objects: messages,mailFolders,events,calendar,calendars,outlook,inferenceClassification. Uri: https:\/\/graph.microsoft.com\/v1.0\/me<\/p><\/blockquote>\n
Looks similar to the errors I go initially, except this one is for groups rather than users.<\/p>\n
Invoke an HTTP Request (Azure AD)<\/h3>\n
I have used this one in the past. Here<\/a> and here<\/a>. It needs the following pieces of info to create a connection:<\/p>\n
\"\"<\/p>\n
The docs are super useless<\/a>.<\/p>\n
\"\"<\/p>\n
The Base URL is the base<\/em> URL. But it must be in the form of a GUID?<\/p>\n
And the Azure AD Resource URI is usually the Base URL, but it could be an identifier.<\/p>\n
For Key Vaults I have done:<\/p>\n
