Could not create prospect in Pardot: “Invalid prospect ID” error

  • 5 November 2021

We are using Zapier to connect LinkedIn Registrations Form with Pardot. We managed to create a prospect after someone registered on the LinkedIn registrations form. The next step is adding them to a list, but after that we received the error: “The subscribed prospect could not be sent to Pardot.” “Could not create prospect.: Invalid prospect ID. Error code: 3”. 

Can someone help us with this error?

Hi @Dylana 

Please post screenshots with how your Zap step is configured that has the error, thanks.


Make sure you are mapping the Prospect ID from Pardot across the Zap steps.
