Custom attributes

Hi, i use this plugin with One login saml. For standard SSO login it works correctly adding email, fisrt name and last name to db.
I need to pass others attributes like ‘profession’ and ‘specialty’ that Isp already passes me with these names, so i need to intercept them and pass it to db to filter users by profession/specialty.

Is there a filter to do this job? Or is there a way to add in backend these fields.

I’ve just added custom field in users profiled waiting to values to fill them.

thanks
