Data Format for Contact List Column Type


We are using the Slack integration to add a row to a sheet through a Slack workflow. We are getting stuck with one column, it's failing when we try and populate a 'Contact List' column. Tried the following formats:

  • FirstName LastName
  • Email
  • FirstName LastName <Email>
  • FirstName LastName (Email)

Is there a way to populate this column type from an integration? What's the data format?

BONUS: This column type supports multiple recipients, what's the format for multiple recipients?
