Amazon Simple Notification Service (SNS) is a fully managed messaging service provided by AWS. It is designed to facilitate the sending of notifications and messages to a variety of endpoints, including mobile devices, email, and other distributed services. SNS is commonly used for sending alerts, notifications, and updates to users or systems in real-time.
When working with AWS SNS, you may encounter the InvalidClientTokenId
error. This error typically manifests when attempting to perform operations such as publishing messages or subscribing endpoints. The error message indicates that the client token ID being used is not valid.

This can happen due to several reasons, such as expired credentials, incorrect configuration, or using the wrong AWS account.
To resolve the InvalidClientTokenId
error, follow these steps:
Ensure that the AWS Access Key ID and Secret Access Key are correct. You can verify your credentials by checking the AWS Management Console:

Ensure that your AWS CLI or SDK is configured correctly:

and enter the correct credentials.For more information on managing AWS credentials, refer to the AWS Security Credentials Documentation. If you continue to experience issues, consider reaching out to AWS Support for further assistance.
