This plugin allows your visitors to subscribe to your push notifications as well as receive push notifications whenever you publish a new post.
The process of subscription is 100% automated and your subscribers will be saved within your DigitalPUSH account.
The process of sending notifications on a new post is also 100% automated and it will notify all your previously subscribed users with the following information: 
* Post title ( up to 64 characters ) 
* Post content without any HTML tags ( up to 128 characters ) 
* Post permalink 
* Post featured image ( If the post has no featured image, a standard bell image will be used instead. The same applies if your featured image is http:// instead of https:// )
The subscription is made by implementing the DigitalPUSH javascript library into your pages ( https://cdn.digitalpush.org/lib.js ), library which handles the entire process. 
The push notification sending process is handled by making a POST call from the plugin to the DigitalPUSH API ( https://api.digitalpush.org/push/ ).

Publisher Common ID (PubCID) is a privacy centric first party cookie solution. Built with consumer privacy in mind. PubCID does not sync IDs across domains so the IDs your domain generates are yours to share with whom you choose. Because the user IDs generated are site specific, there is no degradation of these IDs over time, improving user match rates. Additionally, latency issues generally caused by multiple call outs to various parties are significantly reduced, improving user experience, viewability and earnings.
Publishers that have implemented PubCID have seen an immediate lift in earnings and improvement in user interaction on their domain. This solution is open source, free to use, and does not require any consortium memberships.
<h4>Technical Description</h4>
The PubCID plugin supplements the JavaScript by rewriting PubCID as a server-side cookie to accommodate a custom expiration time frame. By default, it only updates cookies that have been generated by other sources and can also be configured to check consent strings and generate IDs directly.
A new rest endpoint is added that returns a 1×1 pixel and to update the cookie. The URL is ‘/wp-json/pubcid/v1/extend/’. The trailing slash is required. This allows caching to be used as long as the endpoint itself is excluded.
<h4>Working with Prebid</h4>
Requires Prebid.js User Id modules with pubCommonId. Set params.pixelUrl to ‘/wp-json/pubcid/v1/extend/’.
<h4>Generating ID Directly</h4>
The PubCID plugin can be configured to generate IDs directly from your domain by setting the Consent Function and the Generate Function in the settings of the page as outlined below.
Consent Function – This can be a custom function name, or a function provided by other plugins. It should return true if there is user consent. If omitted, it’s treated as having consent and the consent is derived from other means such as JavaScript.
Generate Function – Specify wp_generate_uuid4, this will return a random UUID.
