I'm a beginner with MS Graph,
After a few days trying to use MS Graph API on Postman, following this guide https://learn.microsoft.com/en-us/graph/use-postman
At first I got "OrganizationFromTenantGuidNotFound" when trying to call "https://graph.microsoft.com/v1.0/me/messages" or the events endpoint
So yesterday I started to get
And I didn't changed a thing, so I'm unsure of what I'm doing wrong
I can access some endpoints, like "https://graph.microsoft.com/v1.0/me" and "https://graph.microsoft.com/v1.0/users", but I need to call the events endpoint
Besides, I can make all the calls normally with MS Graph Explorer and using MS Graph Explorer token on postman too
I would be very grateful if someone could point me to the right direction.
What kind of account do you have, are you using OrgID or MSA, do you have a mailbox enabled for said account and where is the mailbox located? Also are you saying that the call works on Graph explorer but not on Postman?
Hi Michev!
I'm using a personal account and MSA.
I have a mailbox on that account, that I use daily, the mailbox domain is hotmail, I'm not sure if this is what are you asking
And yes, the calls works on Graph explorer, but I get this error on Postman
Thanks!
If the same query works fine with Graph explorer, the issue is most likely with the token you are using within Postman. Make sure said token contains the relevant scope/permissions to read messages, at minimum Mail.ReadBasic.
I have the following permissions with admin consent on my azure portal
I shouldn't get events results, but I think it should be enough to get mails on delegated request
Also, when I copy Graph explorer token and paste on postman, it works fine
The issue is most likely in how you're getting the token with Postman, once you obtain it you can check whether any of the required permission is listed by using tools such as jwt.ms/jwt.io.
I don't know which information about the token I can post here or not, but I believe that these are the scope infos that came with my token, so it appears to be right
"scp": "Mail.Read Mail.ReadBasic User.Read profile openid email"
I tried also, to check MS Graph explorer token on this both jwt.ms and jwt.io, but in any of then, they decodified any info
Not sure what you mean by the last sentence, but I'm still thinking that the issue is with the way you obtain a token in Postman. Apart from the permissions/scope, you need to make sure the token is set to the right audience, overall it's best if you compare the two tokens field by field. Another thing to keep in mind is that you can only use the /me endpoint when running in the delegate permissions model, for application permissions this will not work. You can use /users/{userid}/messages though.
Hi Michev!
Sorry for the delay, so
On the last sentence, I said that when I pick Graph Explorer token, and put it on jwt.ms, It doesn't output anything, the "Decoded token" field remains empty,
So I can't compare the two tokens, since I can't get the infos about the Graph explorer one, maybe its a special token for MS Graph?
By 'the right audience', you mean using delegated requests? I'm using then, but for a test, I tried using a application request and got the same error
Not sure mate, I can tell you that it works just fine for my outlook.com account via Postman too:
Hmm, right, I don't know what to test anymore,
I used this tutorial https://learn.microsoft.com/en-us/graph/use-postman to try the requests,
There's something that you think I should change?
