Now you'll have a new "Developer" option under the MemberPress Menu.
Step 2: Connect Zapier to MemberPress
Login to your Zapier.com account and click on My Apps.
Then search for "memberpress" and select it.
Step 3: Create your first Zap using MemberPress
Create a Member/Transaction in MemberPress when a new Subscriber joins a MailChimp list
In this example, we are going to add a new Member to our MemberPress site and make them active on a free Membership level. Let's say we have a MailChimp opt-in form that we use to collect email addresses for our list. As a benefit to them joining the list, we're giving them access to a free membership on our website. With Zapier this will be much simpler to accomplish - and cheaper than hiring a developer to boot.
