System Field isn’t visible, How to use it?

You will not see suggestions for all these above fields on the flow builder. If you want to send the data to Google Sheets or any similar built-in integration, and you don’t see the system field on the list, you can create a Custom field and transfer the System field value to your Custom field using the action “Set Custom Field“.

In order to use the invisible system fields:

  1. Click on Add Content in your bot flow and choose Actions

  2. Click on Set Custom Field. Keep in mind if you didn't define your Custom Field, you need to create your custom Field first


  1. Choose your Custom Field and enter your desired System Field in the Value field.
