Hi @Jorogumo4,

This should have been configured for you, when you chose "Record List" in UI Builder. 

It's part of the preset and looks like this:

If you decided not to use the preset, you could get the sys_id of the record with: 

@payload.cell.metadata.referenceSysId

Let me know if it works out for you 🙂 

Kind regards,

Tiril
