It is noticeable that this is now the third time that the solution to your question can be found in the documentation. Can you tell me why you could not find this information? I am asking this to find out if there may be obstacles that we can remove to make it easier for you to get the information you need in the future.

And by the way, you use the German forum instead of the one for questions in English:

@naledre Thanks for your reply.

Next time I will post in English Form.

This way you will get an error message because it is an incomplete request. How to make requests is also written in the documentation:

Altair, as mentioned in the doc, is a useful first choice for test requests.

Here you can find the GraphQL Schema definition:
