Hi rapidM2M Community,
I still have problems to get connection to Backend.
The rapidM2M Studio shows the BUT not ready!
Also It is not possible to make the API available under
I get this Message:
Whats the Problem and how can I make the API available?
Best regards,

Hello @mklueh,

you may not have activated the API. A guide on how to activate the API can be found here: Activating the API

Kind regards

Hello Josef,
thanks for the fast response.
I already tried to activate the API as shown in this manual.
But when I set the hook to available and klick on safe, I get no feedback from the website.
Do think its a problem of MT or somthing like that, what can I do?
King regard,
