I'm doing Office365 account-based login functionality through SharePoint on PHP.
After doing that I was able to login and get the SPAppToken and SPSiteUrl I use them to get the refreshToken, then I get the accessToken based on the refreshToken

Continue to trying to get the information of the logged in user but failed. Information is as follows:

URL: https://mypage.sharepoint.com/_api/web/currentuser
Method: GET
Headers:
Accept: application/json; odata=verbose
Authorization: Bearer + accessToken

Result:

{
     "error": {
         "code": "-2147024891, System.UnauthorizedAccessException",
         "message": {
             "lang": "ja-JP",
             "value": "Attempted to perform an unauthorized operation."
         }
     }
}

I don't know what to do to be able to get my own credentials API, please help, I think I need somewhere to give permission, but I don't know where it is! Thanks everyone!

I already know my cause!
Because I have not given permission for my login Add-In to create.

I did step 1, but not done step 2

Step 1:

Go to the URL and create the Add-in.
Copy Client Id and Client Secret. And click button Create https://mypage.sharepoint.com/_layouts/15/appregnew.aspx

Step: 2 Go to the URL:
https://mypage.sharepoint.com/_layouts/15/appinv.aspx

Paste Client Id to App Id And paste XML:

<AppPermissionRequests AllowAppOnlyPolicy="true">
    <AppPermissionRequest Scope="http://sharepoint/content/sitecollection/web" Right="Read" />
</AppPermissionRequests>

Click button Create enter image description here

Continue click Trust It and Done
