Hi Rishi,
Attached is the sample code to authenticate AWS API requests sent by HTTP using Signature Version 4. The package has some sample services to upload files to S3 bucket.
Please refer the following KB article Consuming AWS REST APIs from webMethods.
Note: This package was created on 10.5. However, the code should work on 9.12 as well.
Please let me know if you have any questions.
Thanks,
Ram
