Yes, I fear you would need a workaround such as Integromat.

The doer of the event too. The field does not seem to be available in the automations, but it is in the Webhooks and should therefore be available for custom GraphQL applications (and therewith external tools such as Integromat or Zappier).

Ah, I see it now. Thanks. But I need get it when update a regular text field. Guess need check with their developer. 

Also, I can get event’s Date and Time in automation, I wonder if we can get “doer” of the event?

@ping-cheng it seems it depends on the field you want to update. “Creator” is visible for Assignee-fields.

Sorry, I don’t see Creator under General attributes. Is it something to do with configuration?

Thanks.

Yes, this is possible: you can choose “Creator” as the field value on field update.
