Webchat custom fields limit

[Michal_Knazsky]

Hi,
we were trying to implement Auth Chat because it provided possibility to pass any fields to Purecloud Script by signing them. However then we realised we can't do auth version of chat and we have to move to classic unauthorised chat solution. Problem is that documentation says there is limit of 3 custom fields and beside that there are provided fields we don't really need:
firstName: 'John',
lastName: 'Doe',
addressStreet: '64472 Brown Street',
addressCity: 'Lindgrenmouth',
addressPostalCode: '50163-2735',
addressState: 'FL',
phoneNumber: '1-916-892-2045 x293',
phoneType: 'Cell',
customerId: '59606'

Is there any reason why Auth Chat can have random custom fields and classic chat can't? Or maybe just documentation is obsolete?
We would like to pass info about customer's order to Purecloud Script when customer is chatting with our support team, but 3 custom fields aren't enough at all...

Thanks,
MK

You can provide additional fields beyond the 3 specified. But if you do so, you will need to use agent scripts to display those if you want the agent to view them.

Thanks Lucie for fast reply
So is there actually some limit or we can use 10-20 fields easily? We are aware that we need to use script for displaying them to agents.

Should be good with 10-20 fields.
