I have read about the Mautic API and everywhere the term “base URL” is mentioned. What is the base URL fro mautic? And a similar question: In the docs on [https://developer.mautic.org/?php#authorization](https://developer.mautic.org/?php#authorization) it says that I have to send a POST reqest to `/oauth/v1/request_token`. I have my Mautic installed on a VM on 192.168.5.233. But if I navigate the browser to `192.168.5.233/oauth/v1/request_token`, I get a 404 error. Also if I navigate to `http://192.168.5.233/index.php/oauth/v1/request_token`, I get an error JSON wicht says `“Looks like I encountered an error (error #400). If I do it again, please report me to the system administrator!”` and `Code: 400`. ---
