Graph API - Daemon Web 404 Error

Dear Any,

I am testing the Java project I downloaded from
The sample program is working well, from which the used url is "".

But when I change the url to,
it has the error like this "Connection returned HTTP code: 404 with message: Not Found".
( is my Azure AD email.)

Of course, I've added Contacts.Read and Contacts.ReadWrite as API permissions for changed url, and then they are Granted for my API.

I want to know it is possible to access the changed url(
as a background service without sign in.

Please give me some hint or solution to access this url!!!

FYI, I succeeded in accessing this url in the graph-explorer.

Best regards,

I'm not sure how you're making you API call, but you shouldn't be getting 404s at that endpoint. But you can use leverage the graph client package and

const {
} = require("@microsoft/microsoft-graph-client");

const options = {

const client = Client.init(options);

let contacts = await client.api('/me/contacts')

Configuring the authProvider will be dependent on which provider you elect; you can find more details on

Hi, I have tested mentioned script on best triple monitor setup but it showing the issue. Also my developer checked it on another tester device but he was facing issue. After research he updated the script with some coding and boom the script start working. As java some time show issue if there is a minor error in the code so kindly dually check your java script.

Hi @YoungjooYang-6448,

I've updated the tags on your question to get more visibility. By no means am I an expert on Graph but to answer your question, you should be able to access a user's contacts.

Since using the userPrincipalName in the Graph Explorer was successful, have you tried using actual user's id to see if that works. If that's not successful, then it's either the delegate permissions of your app registration or scope variable used to generate the token. Verify in that the token has the appropriate scopes.

Hi Ryanchill,

I think your information is very helpful for me to understand what this situation is.
Specially, I can analyze my access token exactly in you informed me of.
By the way I found out this issue is related to the api, which is not proper for a background service.
So after using "/groups/{id}/members" api, I can access the resource as a background service.

Anyway thank you for your kind answer.

Warm regards,
