Using Zapier with MailerLite

I’ve successfully linked my Zapier to MailerLite for newsletter signups, but there isn’t much instruction on what to change on the form settings. I’ve kept the default settings, but it’s sending me an email instead of sending to MailerLite.

I’m assuming I have to set a POST url, but I have no idea on what exactly I should be setting it to.

adiggy I noticed you said you managed to get this working, any insights?

Bumping this, I can’t seem to find an answer, and their support is lacking.
