wordpress - zapier - convertkit

[in...@guzled.com]

I have set up a web hook in wordpress using the hookpress plugin. I have then gone to Zapier and tried to create a "zap" that will link when a user registers on wordpress to the correct sequence on Convertkit (my email provider). Zapier can't find the web hook. 

I already have a site that uses this exact hook successfully. I've tried to copy what I've done and I'm using the same version on hookpress.

I've activated the zapper hook too.

Any idea why Zapier can't find this web hook?

I attach screenshots below.
