Hello,

With Postman, I could see the tick data actually can be downloaded, then I added

X-Direct-Download header,then, However I am getting below error, Could you advise how I can fix the problem?

<Error>
<Code>InvalidArgument</Code>
<Message>Only one auth mechanism allowed; only the X-Amz-Algorithm query parameter, Signature query string parameter or the Authorization header should be specified</Message>

Hi @noboru.maruyama01

The message will be received, once HTTP client has redirected to AWS with all headers of the original request including the "Authorization" header. Amazon interprets this token as an Amazon token,
causing the request to fail. This is described in this advisory.

To avoid this issue, you configure your HTTP client to disable automatic redirection and then manually do redirection.

Example for Curl command,

1) Get redirect URL, and then store it in an environment variable.

redirect_url="$(curl -I -Ls -H 'Authorization:
Token_xxxxxxxxxxxxxxxxxxxxx' -H 'X-Direct-Download:true'  -X
GET  https://hosted.datascopeapi.reuters.com/RestApi/v1/StandardExtractions/UserPackageDeliveries('<UserPackageDeliveriesID>')/$value
-o /dev/null -w %{url_effective})"

2) Directly download a VBD file from the redirect URL.

curl -k -X GET $redirect_url -o output.gz
