Having joined the IvyTeam not even a month ago, I had to think about what I wanted to accomplish during the Code Camp. Luckily, since I was well aware of this event and also because of the recurring Cool Stuff Days, I started writing down general ideas pretty much from day one.
During the development of my first connector for the Axon Ivy Market, I created a REST Client and used the Generate REST classes feature with the corresponding OpenAPI Definition to quickly make all the Endpoints available. While using these Endpoints in Processes, I noticed that all the Parameters specified in the OpenAPI Definition where neatly and automatically put in place for me. Therefore, I simply had to fill in their desired values.

However, I also noticed that the same thing wasn't true for the Headers. This does make sense since usually you create a custom Feature with a ClientRequestFilter to automatically add all the necessary Headers to your Requests. But still, it would be nice to be able to see and add the Headers which have been specified in the OpenApi Definition, wouldn't it? And there already is a drop-down Menu when choosing the name of a Header with some widely used options to choose from. So, why not add the explicitly mentioned Headers to this Menu? And that's exactly what I did.

Now, you can see all the specified Headers at the top of the drop-down Menu.
