With <a href="https://github.com/App-vNext/Polly">Polly</a> it is possible to create complex and advanced scenarios for error handling with just a few lines of code.</p> <p>This week I was connecting an eCommerce web application to an ERP system with REST APIs. There are multiple endpoints, all authenticated with OAuth. To make sure all calls to the APIs will have a high success rate I had to implement retry mechanisms for different scenarios.</p>
