Now what has TCP to do with HTTP? Think of HTTP as the command language for both computers so they are able to communicate. TCP is used a lot for scenarios in which one computer sends something to another.

When you read this blog post, TCP manages the channels between your browser (hope you are using Microsoft Edge) and the server. The transfer of resources (like html files, images, videos etc) happens with TCP - which again is acronym, for Transmission Control Protocol. ) - Data needs to be transferred from Point A to Point B over the network. Its purpose is to structure requests and responses over the internet (yeah, you heard of that one :smiling_face_with_halo: HTTP is the acronym for Hypertext Transfer Protocol.

HTTP requests are a super powerful thing - not only in Power Automate! We will first need to understand what this is in order to determine why we would like to know how to use them. What is a HTTP request and why would I need it? If you ever wondered what is an HTTP request and why you would want to know how this works - this post is made for you. Then we open the run history, and have a look at the Outputs of the Compose action and copy everything inside of that box.

As already mentioned, we can see the JSON code in our run history, which is why we save our unfinished flow and let it run. How do we solve this now? Well, we parse JSON, which means that we turn the code into objects again and those objects are then reflected in the Dynamic Content in Power Automate.Д«efore we add the Parse JSON action, we need to find out, WHICH JSON we need to parse. Now to the interesting part of this flow: We want to exactly post this random list item but we if we look into our Dynamic Content, it gives us only content from the Get items action, but that is before we get a random list item, and as we do't want to tweet ALL list items, this isn't a good idea. The output of this Compose action will reflect a random list item. The arguments inside of the expression 1,length(body('Get_items')?) mean that our flow needs to pick a random number between 1 and (as this value could change over time) the amount of list items (which is expressed by our length(body('Get_items')?))expression. We use the rand() expression to get a random list item from that list.
