From a Google cloud application, I need to open a file located in my project’s cloud storage. I tried to use a URL of the following form to access the file but I get the error below:
http://storage.googleapis.com/my-bucket/my-file
Error: Access denied. Anonymous caller does not have storage objects
www.googleapis.com/upload/storage/v1/b/http://my_appl//my-bucket/my-file
Error 404
www.googleapis.com/storage/v1/b/my-bucket/my-file
Error 404
https://www.googleapis.com/storage/v1/b/my-bucket/o/my-file
"code": 401,
"message": "Anonymous caller does not have storage.objects.get access to my-bucket/my-file
https://www.googleapis.com/storage/v1/b/my-bucket/o/my-file/place?key=my-key
Not found
Am I composing the URL incorrectly?
http://storage.googleapis.com/my-bucket/my-file
This one is fine. However, unless an object is publicly readable, you'll need to authorize the request, which means either including an "Authorization" header in the request with appropriate credentials or signing the URL with the private key of a service account.
https://www.googleapis.com/download/storage/v1/b/my-bucket/o/my-file?key=my-key&alt=media
This is also okay, but an API key does not provide authentication. You'll still need an Authorization header unless the object is publicly viewable.

I have configured our Azure Data Factory with a REST Link Service. I have obtained a valid token from the end service.
The token successfully works when using the token with POSTMAN, but the token returns Error status code 401 Unauthorized with Azure Data Factory.
As you can see with POSTMAN when I send a GET request with the Token I get data back:
However, with Azure Data Factory I get the error:
{
"errorCode": "2200",
"message": "Failure happened on 'Source' side. ErrorCode=RestCallFailedWithClientError,'Type=Microsoft.DataTransfer.Common.Shared.HybridDeliveryException,Message=Rest call failed with client error, status code 401 Unauthorized, please check your activity settings.\nRequest URL: https://pm2.preqinsolutions.com/apiCore/api/countries.\nResponse: ,Source=Microsoft.DataTransfer.ClientLibrary,'",
"failureType": "UserError",
"target": "Copy data1",
"details": []
}
The ADF Link Service is a follows:
Can someone see something obvioius that would prevent access due 401 Unauthorized status with ADF?
I have also tried the following ADF configuration. However, I'm getting the same error:
Please try changing the authHeader name to Authorization and the value to Bearer <your API key>. I suspect from the screenshot of Postman that is what it’s doing. If that does not work then please provide a link to the documentation. This explains Bearer tokens.
You might also check the lifetime of your access token and make sure it doesn’t expire after an hour, for example.
I did a quick test against a REST API I know (Power BI REST API). The linked service looks like this and the value for the Authorization header was Bearer MY_ACCESS_TOKEN_HERE.
The dataset looks like:
The source of the Copy activity looks like:
This succeeded.
I would suggest you contact pm2.preqinsolutions.com support to see if they can provide more information on your access token / API key and have them confirm that the API isn't restricted to be accessed from only certain allowed API addresses. (ADF will not be accessing it from an on-premises IP address like your laptop.) You might also change the REST API linked service to use a self-hosted integration runtime instead of an Azure integration runtime to validate the IP address the API is called from isn't the issue.
The Paypal API doesn't recognize my Client ID and Secret I got from https://developer.paypal.com/developer/applications/
I wanted to include a server side checkout according to this tutorial https://developer.paypal.com/docs/archive/checkout/how-to/server-integration/
When I do the request to https://api-m.paypal.com/v1/payments/payment I always get a 401 Error with the message "Authentication failed due to invalid authentication credentials or a missing Authorization header.".
I checked multiple times if my credentials were correctly included into the request. I also tested the endpoint in my server environment and as well via Postman.
I also tried the route https://api-m.sandbox.paypal.com/v1/oauth2/token to exchange my credentials with an access token and got the same problem.
I also tried to create multiple Sandbox and Live Accounts and always got the same error.
Has anyone an idea what the problem could be?
There are two separate issues here.
You first need to use /v1/oauth2/token to obtain an access token, and then use that access token to call any of the other actual APIs.
The credentials you obtain from PayPal Developer will be for either "Sandbox", or "Live". Make sure you choose the correct tab (sandbox, for development). Sandbox credentials will only work for api-m.sandbox.paypal.com , and Live credentials will only work for api-m.paypal.com . The two environments are completely separate.
If you still have issues, post the SANDBOX client ID and secret you are using, and the full request and response to the api-m.sandbox.paypal.com endpoint. There should be a PayPal-Debug-Id in any error response, in the headers if nowhere else.
I am trying to create a signed URL for a private object stored in cloud storage.
The storage client is being created using a service account that has the Storage Admin role:
storage_client = storage.Client.from_service_account_json('service.json')
bucket = storage_client.bucket(bucket_name)
blob = bucket.blob(blob_name)
url = blob.generate_signed_url(
version="v4",
# This URL is valid for 15 minutes
expiration=datetime.timedelta(minutes=15),
# Allow GET requests using this URL.
method="GET"
)
This generates a URL that when accessed via a browser gives this error:
<Error>
<Code>AccessDenied</Code>
<Message>Access denied.</Message>
<Details>Anonymous caller does not have storage.objects.get access to the Google Cloud Storage object.</Details>
</Error>
What am I missing here? The service account has no problem interacting with the bucket or blob normally - I can download it/etc. It's just the Signed URL that doesn't work. I can make the object public and then download it - but that defeats the purpose of being able to generate a signed URL.
All of the other answers I've found seem to focus on issues using application default credentials or are very old examples from the v2 API.
Clearly there's something about how I'm using the service account - do I need to explicitly give it permissions on that particular object? Is the Storage Admin role not enough in this context?
Going crazy with this. Please help!
I'm using Azure Media Services. I have an encoded asset placed there with Content Key and Asset Delivery Policy. I'm also using the Token restriction.
I am able to stream the video well on localhost but as soon as I deployed the application to the server it stopped streaming and giving an error code: 0x20500006 (of Azure Media Player).
When I checked all the requests I found that there is a request to Key Delivery service with some KID and it returned the following response:
<Error>
<Message>
Failed authorization policy evaluation.
</Message>
<Code>
Unauthorized
</Code>
</Error>
I am using the HTTPS protocol on the server also tried over HTTP as well but got no response.
I responded to your post on MSDN. Posting on here for visibility.
"There are different reasons for the unauthorized error. It may be due to one of the following reasons:
Missing authentication header.
Bad authentication header value.
-The token has expired.
-The token contains an invalid signature.
Policy misconfiguration
No token in the request
Please double check to make sure your token has not expired. Also, for the Media Services REST request to succeed, the calling user must be a Contributor or Owner role in the Media Services account it is trying to access. For more information, see this documentation about Access control."
I am facing the issue in calling the OneDrive for Business API to work. Below are the steps I have followed till now:
Created a Web App/API application in Microsoft Azure Portal (A very tricky process). Gave all the permissions.
Got Application ID (A_ID) from there.
Went to the URL to get the 'code' via browser:
https://login.microsoftonline.com/common/oauth2/authorize?response_type=code&client_id=<A_ID>&redirect_uri=<URI>
Got the code. Did a callout via POSTMAN (using the code, client ID, client secret and redirect URI) to the URL: https://login.microsoftonline.com/common/oauth2/token
Received an Access Token (AT) and other details.
NOW, when I want to use this AT to upload a file, I am getting the error. The URI is: https://<tenant>/_api/v2.0/me/drive/root:/Abc.txt:/content. For headers, I am passing: Authorization-> Bearer AT; Content-Type -> application/octet-stream
The error is:
{"error":{"code":"unauthenticated","message":"Token contains invalid signature.","innerError":{"code":"invalidSignature"}}}
I don't know where the issue is. Is it in the tenant name I am using (There is a chance that I might be using it wrong!) OR is it in the permissions OR I have not set up the app in the Azure Portal correctly OR is it something entirely different.
