Adding Leads to Exhausted Content Nurture Campaign - what trigger to use?
I have created a nurture campaign to engage leads who already exhausted content in multiple nurture campaigns. I have set up the Smart Lists using the trigger Fills Out Form for the majority of the programs.

However, I have one program where there is no form fill. The lead is created by an API.

What trigger do I use to add the leads from this API to the exhausted content nurture campaign? Appreciate your help!
