Linking landingi.com with redlink.co.uk; over API or through zapier

I'm launching a campaign to acquire leads.

The landing page (screen) is on landingi.com in my subdomain. The entire site is on wordpress.

The ideal scenario is as follows:

1. the customer enters his data (e-mail + phone number)

2. this data lands in a specific audience on redlink.com.

landingi.com has the ability to directly integrate with many platforms, including google sheets, but not with redlink.pl, which provides an API ABOUT HERE .

De facto integration would be about automatically transferring data to redlink immediately after it appears in google sheets.

Perhaps it would be easier to integrate redlink through the zapier.com platform, however, this will increase costs.
