Before we do anything, we need to create a free account on Trello so that you can see the boards, cards, and lists that have been created. Alternatively, you can install the Windows 10 Trello application if applicable. If you are having trouble generating cards with the microservice as is, please go to https://trello.com/app-key and generate your own key. Once you have done that, simply replace the key with your newly generated one in the following call in the OnStart method:

trello = new Trello("9dbf8c09499d07abac02bbd6d5af4b9c");

Replace the token you get with the one in this call (the same method):

trello.Authorize("95da70bf03bd43b82648f515477d44ec84baa2fb9e811cb7284be10d94512b81");

Next, let's go ahead and create another Console App (.NET Framework) for our microservice. We will name this one TrelloMicroService:

For this microservice, we will be using an open source package, TrelloNet, which makes working with Trello and its REST API very simple. In fact, it makes it perfect for programmatic implementation within a microservice. Imagine you receive an email with specific words in it, and from that you automatically create a ticket, assign it, and give it a due date. Based upon a reaction to a specific event, you could then automatically close out tickets and boards if you so desired.

Let's install our TrelloNet NuGet package, as shown in the following screenshot:
