Manage newsletter signups in Baserow

This is the workflow that I presented at the April 9, 2021 n8n Meetup. This workflow uses Baserow.io to store registration information collected using n8n as both the web server and the data processor. To get this workflow working properly, you will either need to run it on n8n.cloud or using the on premise version with people having the ability to connect to n8n externally. You will need an account on Baserow.io to store your subscriptions with a table with the following fields: GUID First Name Last Name Email Confirmed

Help me set up the n8n workflow "Manage newsletter signups in Baserow" (https://n8n.io/workflows/1028). It uses: Send Email, HTTP Request. Import the template JSON into my n8n instance, list every credential I need to create, and walk me through testing it.
