I want to create an integration between Zapier, RD Station Marketing, and a Google Sheets spreadsheet.
Basically, the spreadsheet is automatically populated with data from customers who log into the community every day.
By integrating Zapier with RD Station, I want Zapier to check if that login (email) is appearing in the spreadsheet for the first time — which would mean it's that person's first login.
As soon as Zapier identifies the email for the first time, I want it to send this information to RD Station Marketing so I can trigger an automation based on it.
I know how to set things up in RD Station, but I’m not sure how to configure this in Zapier.
Who can help me with that?
