Retry and fallback policies in C# with Polly

2019-04-18

In this blog I will try to explain how one can create clean and effective policies to retry API calls and have fallbacks when requests are failing. With Polly it is possible to create complex and advanced scenarios for error handling with just a few lines of code.

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.

Things I Learned This Week - #1

My plan was to write a quick post about some cool things I found and learned this week but I just learned too much (as I do every week). Below are just the highlights, I will try and write more posts like this, especially if I get some cool comments :)
