Discourse サブスクリプションプラグイン

[Discourse]

	Summary	The Discourse Subscriptions plugin allows site owners to sell recurring and one-time purchase subscriptions that grant access to a group on a Discourse instance.
	Install Guide	This plugin is bundled with Discourse core. There is no need to install the plugin separately.

As this is an official plugin maintained by the Discourse team, Support, Bug, UX, and Feature requests can be made in the respective categories here on Meta, and tagged with the appropriate plugin tag. Click on a link below to get one started.

Support Bug UX Feature

The Discourse Subscriptions plugin allows you to create one-time as well as recurring subscriptions that users can pay for in order to access gated content. This can be a great way to fund the hosting cost of your community.

Features

The Discourse Subscriptions plugin supports the following features:

• Create new products and plans from the admin panel
• Cancel and refund subscriptions from the admin panel
• Create one time purchase or recurring subscription plans
• Add free trials on recurring subscriptions
• SCA/3D Secure support
• Add/remove users from plan groups as they subscribe/cancel
• Cancel subscription from user profile
• Cancellation of subscription at end of subscription period
• Optional Support for Stripe Checkout
• Automatic sales tax calculation and collection
• Users can update their card for individual subscriptions

The “Subscribe” button located in the top nav will take you to the Subscribe page /s where it lists the subscriptions you have configured for your site:

Once a user clicks on one of the “Subscribe” button for a specific plan it will open up the payment page for that plan:

After a user fills out their payment details and their address and click “Subscribe”, they are shown a “Thank you!” message and taken to their billing page:

The user is also automatically added to a group of your choosing so that you can easily see which users have subscribed as well as provide gated content in categories only that group can see.

Terms

• Subscription - Subscriptions are a recurring payment plan which allow you to control access to content on your community. When a subscription is created or deleted, a user is added or removed from the user group you associate with your subscription plan. A subscription is made up of a product and plans.
• Product - A product in Stripe’s terms is what you’re selling. A product can contain one or more plans.
  • To add a description to your product, add a metadata field named “description” and use that one instead. You can use Markdown.
• Plan - A plan contains a price, recurring cycle, and associates with a group to which your subscribers gain access.

Be very careful to keep your Stripe private keys safe and secure at all times.

If you were to shut down your instance of Discourse, uninstall this plugin or your site were to go offline, Stripe will continue to bill your customers for your service until the subscription is cancelled.

Configuration

1. Install & enable the plugin
2. Configure Payment Gateway (Stripe)
3. Configure Webhooks & Events in Stripe
4. Add your Stripe keys (public, secret, webhook secret) under Admin > Plugins > Installed > Subscriptions > Settings /admin/site_settings/category/discourse_subscriptions?filter=plugin%3Adiscourse-subscriptions.
5. Create a group for your subscribers to join via purchase
6. Create a product and plan under Admin > Plugins > Subscriptions
7. Profit!

Set up your Payment Gateway.

Firstly, you’ll need an account with the Stripe payment gateway. To get started, you can set up an account in test mode and see how it all works without making any real transactions or having to set up a bank account. There is no test mode toggle in the plugin; instead, be sure to use your developer keys (they begin with pk_test, sk_test)

Set up Webhooks and Events in your Stripe account

Webhooks are required to make subscription cancellations work fully. Be sure you have them configured correctly.

Once you have an account on Stripe, you’ll need to tell Stripe your website’s address so it can notify you about certain transactions. You can enter this in your Stripe dashboard under Endpoints > URL.

Webhooks address: [your server address]/s/hooks – where [your server address] is the URL of your Discourse install.

You’ll also need to tell Stripe which events it should notify you about via the webhook URL.

Currently, Discourse Subscriptions responds to the following events:

• customer.subscription.deleted
• customer.subscription.updated
• checkout.session.completed

Add the Stripe API and Webhook keys to your plugin settings

Stripe needs to be authorized to communicate with your website. To do this, it publishes a pair of private and public API keys and a signing secret for your web hooks.

To authorize webhooks, add the API keys and webhook secret from Stripe to your settings page (under Developers).

Adding production keys will make live payments. If you plan to test, be sure to switch to View test data mode and get pk_test and sk_test keys under Developers.

In your Stripe account settings, see:

• https://dashboard.stripe.com/apikeys
• https://dashboard.stripe.com/webhooks

Add these keys under the appropriate settings in Admin > Plugins > Installed > Subscriptions > Settings /admin/site_settings/category/discourse_subscriptions?filter=plugin%3Adiscourse-subscriptions.

Set up your User Groups in Discourse

When a user successfully subscribes to your Discourse application, after their credit card transaction has been processed, they are added to a User Group. By assigning users to a User Group, you can manage what your users have access to on your website. User groups are a core functionality of Discourse and this plugin does nothing with them except add and remove users from the group you associated with your Plan.

Create one or more products with plans.

Under Admin > Plugins > Subscriptions, click add a new Product. Once you have a product saved, you can add plans to it. Keep in mind that the pricing and billing intervals of plans cannot be changed once you create them. This is to avoid confusion around subscription management.

If you take a look at your Stripe Dashboard, you’ll see all those products and plans are listed. Discourse Subscriptions does not create them locally. They are created in Stripe.

Testing

Test with these credit card numbers:

• 4242 4242 4242 4242
• 4111 1111 1111 1111 (no authentication required)
• 4000 0027 6000 3184 (authentication required)

For more test card numbers: Test card numbers | Stripe Documentation

Visit /s and enter a few test transactions.

Going Live

Once you’re ready to go live, change your API and webhook secret keys to production keys. You will need to create new products and plans in live mode.

Do be aware that if if you don’t properly configure Stripe webhooks, and recurring payments fail to process for any reason (expired credit card, etc.), users will still have access to the group . To have Stripe automatically cancel subscriptions, be sure to set your Manage failed payments settings similar to the below image and configure webhooks as described above.

Update Payment Info

Users can update their card used for individual subscriptions by visiting the billing page and clicking the edit button next to the subscription which will open up this screen:

Stripe Checkout with Stripe Pricing Tables

You can also opt to replace the Subscription Plugin product and checkout pages and instead use Stripe Checkout with Stripe Pricing Tables.

In your Stripe Dashboard:

1. After you’ve created the products on Discourse, Go to Products > Product catalog
2. Click on the product you’d like to include in the pricing table
3. Click Edit product
4. More Options and enter the following under Metadata:
   • Key: group_name
   • Value: The group’s name on Discourse (e.g., trust_level_0)
5. Click Update product to save

Make sure the group name matches the group that is selected under User_Groups on Discourse

Create your Stripe pricing table

1. Go to Products > Pricing tables
2. Create a new table and add the products you just created
3. After publishing the table, copy the pricing table ID found within the embed code (it starts with prctbl_...)
4. Paste the pricing table ID into your discourse_subscriptions_pricing_table_id and enable the subscriptions pricing table setting.
5. Click the green checkmarks to save both settings.

Recommended step:

When setting up the Pricing Table inside of Stripe it is recommended to link the user to your site after checkout is complete otherwise they will stay on a Stripe confirmation page without a link back to your site.

Redirecting to https://<your-site>/my/billing/subscriptions is a good choice for subscriptions. For one-off payments you could link directly to https://<your-site>/my/billing/payments.

Automatic Tax Collecting

To enable Automatic Tax Collecting check the Site Setting box for discourse_subscriptions_enable_automatic_tax.

If you enable it, but you have not configured your Stripe instance properly to collect tax users may see this popup after completing the checkout process:

There is this guide for more info, but there shouldn’t be much to do since the plugin is now passing in the appropriate automatic_tax[enabled]=true parameter (step 5).

Be sure you configure your registrations (step 4) as well:

Here is an example Discourse Subscription Plugin transaction in Stripe showing that tax was automatically collected:
