[StarfallProjects]

@Joffcom not 100% sure if this is what you actually meant in the ticket? Could people use both authenticate and auth?

@StarfallProjects Auth is a property like body / header / qs it lets you use Basic Auth as an authentication option so you would use it like...

authenticate: IAuthenticateGeneric = {
  type: 'generic',
  properties: {
    auth: {
      username: '={{$credentials.username}}',
      password: '={{$credentials.password}}',
    },
  },
};
