Authenticate using AWS Signature

AWS Signature is the authorization workflow for Amazon Web Services requests. AWS uses a custom HTTP scheme based on a keyed-HMAC (Hash Message Authentication Code) for authentication.

The official AWS Signature documentation provides more detail:

• Signing and Authenticating Requests

• How to call an API

To use AWS Signature, do the following:

1. In the Auth tab for a request, select AWS Sig V4 from dropdown list.

2. Enter your AccessKeyID and SecretKey values.

For extra security, integrate Bruno with your secret manager to store these values in a single location. Learn more here.

The AWS Signature parameters are as follows:

• Session Token - Required only when using temporary security credentials.
• Service Name - The service receiving the request.
• AWS Region - The region receiving the request.
• Profile Name - name of your AWS signing profile
