Hey Mautic Team,  
  
  
  
I am developer and integrating mautic api [https://developer.mautic.org](https://developer.mautic.org). I am basically creating new contact using api and it was working. yesterday i found an issue with it. it returns 400 status code with message #: This form should not contain extra fields. however it works for already registered contacts. i also find solution [https://github.com/mautic/mautic/issues/1136](https://github.com/mautic/mautic/issues/1136) but i don’t know how it works. screenshot is also attached. Help me figure out this problem

The same thing is happening to me after I migrated to version 2.1.

I think my issue is with the tags field.

@maxmeinberg @wqsaali  
Same issue was happening with me `This form should not contain extra fields. `  
but it’s working now. I am able to add new contacts.  
can you guys tell me, Is it possible to add tag/tags to contact while adding new contact with Mautic API?
