I have succeeded to make functional API, as oAuth1 and oAuth2. Unfortunately both APIs are not working in the end.  
  
For testing I have used API tester (please see [https://github.com/mautic/api-library/blob/master/apitester/index.php](https://github.com/mautic/api-library/blob/master/apitester/index.php)). I have tried regular Postman callback. Therefore I am not convinced, whether the documentation is valid.  
  
Variant with oAuth1: Authorized - when the lead is input into Mautic, I receive the error: “Invalid token”  
  
Variant with oAuth2: When authorized, I receive parameters code and state. This parameters should be later used for receiving own token. When I get accessToken, there is an error invalid\_grant and error message: “The authorization code has expired”. Unfortunately I haven’t received any parameters, yet.  
  
  
  
Can you help with this one, please?  
  
  
  
Thank you!
