How to Generate an AWS Signature Version 4 in Talend Studio

[Anonymous]

Greetings!

I am trying to connect to an API and want to retrieve data using Get method . However the authorization is required to be on  AWS Signature Version 4 . I tried to use trest and trestclient components in talend studio 7.1.1 version . I didn't find the option where I can pass aws auth parameters like access key ,secret_key, Day, Region, Service . After some research I found that an AWS Signature Version 4 needs to be generated and be passed into the header in the tRest components . However I have not been successful  generating that . There are steps provided by AWS on how to achieve that using java scripts . Yet I found that's too cryptic to implement in Talend . I will greatly appreciate any help along this requirement .

Thanks,

Debashis

Hi Abhishek , I went the python scripting way . You can connect to the API , read the data , load in S3 using python scripts . Then you can call the scripts in Talend Job using tSystem components . Here's more about it .

Thank you. So you use python sdk to do the job . This signature v4 is
tricky.

I would like to call Athena api to execute query. API seems to be good
solution.

Other option are going withSDKs or CLI. Which creates external dependency
