Get CX-Cumulocity-Application-Key

Hi all, I’ve just created a trial account on Cumulocity. I would like to make some API requests to see how easy it would be to integrate into our systems. I’ve read the API docs, it talks about use of the ‘CX-Cumulocity-Application-Key’ header, but I cannot find where I set/get this value.


You only really need this if you are using a c8y custom app.
Without it the call will still succeed.

If you’re looking for a guide on how to use the Cumulocity REST stack, I can help. I did a presentation at International user Group on using the REST stack, designed around new users.

You’ll need to register, which doesn’t cost anything. I heard talk that SwAG was going to put the presentations on YouTube but don’t know if that happened or not.

You only need the application key header if you are making your own apps/microservices. For the built-in ones, you don’t need that.
