Users: Lock your content and capture subscribers instantly.

This WordPress plugin lets you capture subscribers effortlessly. Turn your valuable content into a subscriber magnet. Let visitors unlock Posts with just 1 click via LinkedIn, Google, Facebook or simply their e-mail address.

To get started you need an API key and Publisher ID. You can get these for free at https://contentlockr.com/start-for-free. You’ll also receive login details for your Contentlockr dashboard.

Remote files

The following files are needed to render marketing content (loaded through our API) correctly on the website and collect statistics. We’ve opted to load these files remotely as they’re subject to small and frequent changes. These files are only loaded if you have the tenant set in the config (and you are a Contentlockr customer).

External services

Thirdparty authentication
This plugin connects to the Google and LinkedIn auth APIs which will allow visitors to create a WordPress account using their Google or LinkedIn accounts.
The initial call will be done through our own authentication API after which subsequent calls will be done to Google’s and LinkedIn’s own auth APIs to finalize the account creation. This authentication API is needed so it’s not necessary for the party that installs the plugin to create and configure their own Google and LinkedIn dev accounts.

Contentlockr API

This connection will allow:

  • Synchronizing users from WordPress to the API to allow setting up mailing campaigns.
  • Loading marketing content from the API into the WordPress website.
  • Collect statistics regarding marketing content and pageviews.
