Supported Layouts

Summary

This component enables Web Stories to support paywalls and subscriptions in a manner following amp-subscriptions and amp-subscriptions-google. It enables publishers to configure their Stories to feature paywalls and integrate into their backends via authorization URLs and other configurations.

The way to specify subscriptions configurations is the same for both a classic AMP page and a Web Story. See more details about configurations in amp-subscriptions configuration.

The extension provides a simple UI and capabilities to surface a paywall bottomsheet, and manage blocking / unblocking locked content.

Important Note: Please first read API docs for amp-subscriptions and (optionally) amp-subscriptions-google and ensure you are set up with those basic capabilities before integrating with this component.

How it works

  1. Publishers can configure a Web Story with the component to implement a paywall.
    • Paywall cannot be triggered on the first two pages of a Story or on the last page or on a Story with fewer than 4 pages.
  2. When the user navigates to the first paywalled page of the Story, will check if the user has access via . If yes, the user can consume the Story without any interruption.
  3. If the access is not granted, a paywall bottomsheet is shown at the bottom of the page. The paywall only prevents users from accessing the remaining pages of the Story, the user can otherwise navigate as normal (tap to previous pages, or swipe to a different Story if available).
  4. The paywall has a templated UX that allows for key messages to be customized by the publisher.
  5. Depending on publisher configuration, the dialog can support three different ways to progress:
    • Sign-in with publisher’s sign-in flow (i.e. publisher provided sign-in page).
    • Subscribe directly via the publisher (i.e. via a publisher provided subscription page).
    • If enabled by the publisher, subscribe via Subscribe with Google.
  6. If the user completes any of the above authentication flows, the user is returned to the Story page, the paywall is dismissed and the user can consume the rest of the Story.
  7. If the user encounters a subsequent paywalled Story from this publisher, they will continue to retain access based on amp-subscription mechanisms.

    </amp-story-subscription>
</amp-story>

price {string} required

Subscription/offer price, e.g. "$0.50/week" or "4€ every 4 weeks for one year". This can be any arbitrary string that describe any offers like free trial, monthly, annually, etc. Note that it would be omitted with ellipsis at the end if too long, which is determined by the view width.

description {string} required

One line of description for the subscription/offer.

subscriptions-page-index {number} optional

The index of the amp-story-page that displays the subscriptions dialog. The amp-story-page index in amp-story starts from 0, e.g. the first amp-story-page has index of 0. If not specified, it defaults to 2, which is the 3rd amp-story-page of the story.

Note that this specified page cannot be the first two pages nor the last page of the story.

headline {string} optional

A headline string that describes the subscription/offer. If not provided, the line would be removed, e.g. the dialog would get shorter since the content is one line less.

additional-description {string} optional

Additional line of description for the subscription/offer. If not provided, the line would be removed, e.g. the dialog would get shorter since the content is one line less.
