There is no api key in my api (v3 auth)
How should I operate?

Have you already requested your API Key? If you didn't request...

Go to this page in your profile.

If you don't have your own API Key yet, request it here by clicking "Create" or Request API Key "click here".
If you have already requested your API Key will be on the same link.
