Our cutting-edge platform offers a seamless solution, empowering you to leverage the power of two robust connectors: the AWS Billing Source and the Slack Sink.

AWS Billing

AWS billing is a simple, flexible, cost-effective way to pay for your cloud resources. You only pay for what you use, and you can easily track your costs and usage. AWS billing is essential for gaining control over your cloud expenses, as it enables you to monitor usage, allocate costs effectively, and optimize resources while benefiting from transparent pricing and cost management tools provided by AWS, ensuring you take charge of your cloud budget and maximize the value of your investments.


Slack is a team communication platform that brings together the right people, information, and tools to get work done. It’s where teams can collaborate, share information, and work more efficiently. It’s intuitive interface and robust features streamline teamwork, enabling the effective organization of channels, seamless app integration, simplified project management, real-time messaging, and effortless collaboration, ultimately fostering enhanced productivity and cooperation in your organization.

Setting Up AWS Billing to Slack using Vanus Cloud

We will use Vanus Cloud to demonstrate. First, set up the AWS Billing Source connector by creating and configuring our AWS IAM Credentials.

Step 1: Configure your AWS Credentials

The Access Key ID and Secret Access Key serve as the credentials that allow you to access and manage AWS resources programmatically. The Access Key ID acts as your username, while the Secret Access Key acts as your password. These credentials are unique to each AWS account and should be treated with the utmost care to prevent unauthorized access to your resources.

To get your AWS access key ID and secret access key, you need to create an IAM user in your AWS account. IAM users are used to control access to AWS resources.
