In this blog post, we will guide you through the process of creating a simple .NET 7 API that interacts with DynamoDB. Additionally, we will integrate our SlackBot console application, which we introduced in a previous blog post How to Create a Custom Slack Bot with .NET 7.

This is the second post in the series

💻 How to Create a Custom Slack Bot with .NET 7

🚀 Creating a Minimal API With ASP.NET Core That Interacts With AWS DynamoDB

🔧 Creating and Hosting An Application on AWS Elastic Container Service (ECS)

🚢 Continuous Deployment with GitHub Actions to AWS Elastic Container Service (ECS)

Before we dive into the details, it’s important to note that we could have created everything within the SlackBot console application. If you prefer that approach, feel free to do so. However, in this post, we are creating a separate Web API to allow for future integration with front-end applications, rather than solely relying on the SlackBot console application.

In this post, we are going to cover creating our ASP.NET Core API first. We will then add a ping endpoint to ensure our Web API is working as expected. Next, we will create an IAM role in the AWS Management Console, create a DynamoDB table in the AWS Management Console, add the AWSDynamoDB SDK and finally the code needed to call our DynamoDB table in AWS.
