How to setup and test connection with AWS SigV4 using custom spoke?

[SmitaH]

Hi community, we need to integrate with AWS SigV4, we have successfully tested the connection using GET method in Postman. However, when I am trying to set up the connection from ServiceNow, I am getting 404 error.

We have created a custom AWS spoke via studio, I have also created actions to make the spoke functional. In REST step I have to provide Resource path, query parameters and headers. Can anyone help to configure the REST step? I would appreciate your guidance if anyone knows how to integrate with AWS SigV4 using custom spoke in integration hub.

Thanks in advance!

To set up and test a connection with AWS SigV4 using a custom spoke, you'll need to follow these general steps:

1. Configure the Custom Spoke:

• Create a custom spoke in your network configuration.
• Assign the necessary network settings, such as IP address range, BGP peering, and routing policies.
• Ensure that the custom spoke can communicate with your AWS environment.

2. Obtain AWS Credentials:

• Create an IAM user in your AWS account with appropriate permissions to access the desired AWS services.
• Generate access keys for the IAM user.

3. Set Up SigV4 Authentication:

• Configure your application or service to use SigV4 authentication.
• Provide the AWS access key ID and secret access key when making requests to AWS services.
• Ensure that the requests include the necessary headers and parameters for SigV4 authentication.

4. Test the Connection:

• Make a simple request to an AWS service (e.g., S3, EC2, Lambda) from your custom spoke.
• Verify that the request is authenticated successfully and that you can access the desired resources.

Additional Considerations:

• Security: Implement appropriate security measures to protect your AWS credentials and prevent unauthorized access.
• Customizations: You may need to customize your SigV4 implementation based on specific requirements, such as using a different region or service.
• Troubleshooting: If you encounter issues, review the error messages and documentation for your AWS service and SigV4 implementation.

Example using Python and Boto3:

Python

import boto3

# Replace with your AWS credentials
access_key_id = "YOUR_ACCESS_KEY_ID"
secret_access_key = "YOUR_SECRET_ACCESS_KEY"

# Create an S3 client using SigV4 authentication
s3_client = boto3.client('s3',
                         aws_access_key_id=access_key_id,
                         aws_secret_access_key=secret_access_key)

# List buckets
response = s3_client.list_buckets()
print(response)

Remember to replace the placeholders with your actual AWS credentials and adjust the code to match your specific use case.

For more detailed instructions and examples, refer to the official documentation for AWS SigV4 and the AWS SDK for your programming language.

Hi Alain, thank you for your response, I have created a custom spoke, however I am struggling to configure the AWS sigV4 authentication script where I need to ensure the script autogenerates the signing headers via canonical request and Crypto JS. Can you help me on this part please?
