I am unable to achieve, can somebody please help me with the code to download file with temporary credentials without passing my accesskey and secretkey just like in the method mentioned above?

Thanks Akshay Sing , i dont know how to comment with a code, the code which i tried after your answer is here. I am currently using the below procedure to download images from my S3 bucket and storing them to return a zip of the images to the user. I am excluding the zip-creation code for you:.

To download the file to your temporary server, you must first obtain access to the S3Object you need. In your case, it is slack. You mentioned that you want to use the temporary credentials supplied to you by the IAM role. It's a smart move to not disclose credentials in code and simultaneously ensure that the credentials supplied to the service will be refreshed automatically. You'll need to initialise your s3Client like this:.

Note : Make sure that the IAM role being used actually has read-access to the bucket. In your case, the bucketName would be slack-automation and the key would be the name of the file on the S3 bucket slack. Then, to store the file on your server, use the copyInputStreamToFile function from org. That's it, Thank you all for your help.
