We are using a 3rd party resource to collect email addresses (Hello Bar). The contact list in Hello Bar is linked to Klaviyo using a private API. I would like to put all of the people who sign up via the API into a list / segment so that they enter a flow and are emailed once they enter their email into the Hello Bar widget.
I can’t locate anything in the list / segment and/or in flows that will pick out the people who signed up through that Private API.
Would really appreciate any help!
