+# Breaking change notice for version 15.0.0
+
+## Removal of `ShopifyAPI::Webhooks::Handler`
+
+The `ShopifyAPI::Webhooks::Handler` class has been removed in favor of `ShopifyAPI::Webhooks::WebhookHandler`. The `ShopifyAPI::Webhooks::WebhookHandler` class is now the recommended way to handle webhooks.
+
+Make a module or class that includes or extends `ShopifyAPI::Webhooks::WebhookHandler` and implement the `handle` method which accepts the following named parameters: data: `WebhookMetadata`.
+
+In v14, adding new fields to the callback would become a breaking change. To make this code more flexible, handlers will now receive an object that can be typed and extended.
+
+`data` will have the following keys
+- `topic`, `String` - The topic of the webhook
+- `shop`, `String` - The shop domain of the webhook
+- `body`, `T::Hash[String, T.untyped]`- The body of the webhook
+- `webhook_id`, `String` - The id of the webhook event to [avoid duplicates](https://shopify.dev/docs/apps/webhooks/best-practices#ignore-duplicates)
+- `api_version`, `String` - The api version of the webhook
+
+### New implementation
+```ruby
+module WebhookHandler
+  extend ShopifyAPI::Webhooks::WebhookHandler
+
+  class << self
+    def handle_webhook(data:)
+      puts "Received webhook! topic: #{data.topic} shop: #{data.shop} body: #{data.body} webhook_id: #{data.webhook_id} api_version: #{data.api_version"
+    end
+  end
+end
+```
+
+### Previous implementation
+```ruby
+module WebhookHandler
+  include ShopifyAPI::Webhooks::Handler
+
+  class << self
+    def handle(topic:, shop:, body:)
+      puts "Received webhook! topic: #{topic} shop: #{shop} body: #{body}"
+    end

 ## Session Persistence
 Session persistence is deprecated from the `ShopifyAPI` library gem since [version 12.3.0](https://github.com/Shopify/shopify-api-ruby/blob/main/CHANGELOG.md#version-1230). The responsibility of session storage typically is fulfilled by the web framework middleware.
 This API library's focus is on making requests and facilitate session creation.
 
 ⚠️ If you're not using the [ShopifyApp](https://github.com/Shopify/shopify_app) gem, you may use ShopifyAPI to perform OAuth to create sessions, but you must implement your own session storage method to persist the session information to be used in authenticated API calls.
 
+## Supported Types of OAuth
+> [!TIP]
+> If you are building an embedded app, we **strongly** recommend using [Shopify managed installation](https://shopify.dev/docs/apps/auth/installation#shopify-managed-installation)
+with [token exchange](#token-exchange) instead of the authorization code grant flow.
+
+1. [Token Exchange](#token-exchange)
+    - OAuth flow by exchanging the current user's [session token (shopify id token)](https://shopify.dev/docs/apps/auth/session-tokens) for an
+[access token](https://shopify.dev/docs/apps/auth/access-token-types/online.md).
+    - Recommended and is only available for embedded apps
+    - Doesn't require redirects, which makes authorization faster and prevents flickering when loading the app
+    - Access scope changes are handled by [Shopify managed installation](https://shopify.dev/docs/apps/auth/installation#shopify-managed-installation)
+2. [Authorization Code Grant Flow](#authorization-code-grant-flow)
+    - OAuth flow that requires the app to redirect the user to Shopify for installation/authorization of the app to access the shop's data.
+    - Suitable for non-embedded apps
+    - Installations, and access scope changes are managed by the app
+
 ## Note about Rails
 If using in the Rails framework, we highly recommend you use the [shopify_app](https://github.com/Shopify/shopify_app) gem to perform OAuth, you won't have to follow the instructions below to start your own OAuth flow.
   - See `ShopifyApp`'s [documentation on session storage](https://github.com/Shopify/shopify_app/blob/main/docs/shopify_app/sessions.md#sessions)
 
 If you aren't using Rails, you can look at how the `ShopifyApp` gem handles OAuth flow for further examples:
-- [Session Controller](https://github.com/Shopify/shopify_app/blob/main/app/controllers/shopify_app/sessions_controller.rb)
-  - Triggering and redirecting user to **begin** OAuth flow
-- [Callback Controller](https://github.com/Shopify/shopify_app/blob/main/app/controllers/shopify_app/callback_controller.rb)
-  - Creating / storing sessions to **complete** the OAuth flow
+- Token Exchange Flow
+  - [Token Exchange](https://github.com/Shopify/shopify_app/blob/main/lib/shopify_app/auth/token_exchange.rb)
+    - Completes token exchange flow to get online and offline access tokens
+- Authorization Code Grant Flow
+    - [Session Controller](https://github.com/Shopify/shopify_app/blob/main/app/controllers/shopify_app/sessions_controller.rb)
+      - Triggering and redirecting user to **begin** OAuth flow
+    - [Callback Controller](https://github.com/Shopify/shopify_app/blob/main/app/controllers/shopify_app/callback_controller.rb)
+      - Creating / storing sessions to **complete** the OAuth flow
 
 ## Performing OAuth
+### Token Exchange
 #### Steps
+1. Enable [Shopify managed installation](https://shopify.dev/docs/apps/auth/installation#shopify-managed-installation)
+    by configuring your scopes [through the Shopify CLI](https://shopify.dev/docs/apps/tools/cli/configuration).
+2. [Perform token exchange](#perform-token-exchange) to get an access token.
+
+#### Perform Token Exchange
+Use [`ShopifyAPI::Auth::TokenExchange`](https://github.com/Shopify/shopify-api-ruby/blob/main/lib/shopify_api/auth/token_exchange.rb) to
+exchange a [session token](https://shopify.dev/docs/apps/auth/session-tokens) (Shopify Id Token) for an [access token](https://shopify.dev/docs/apps/auth/access-token-types/online.md).

+This method returns the new `ShopifyAPI::Auth::Session` object from the token exchange, 
+your app should store this `Session` object to be used later [when making authenticated API calls](#using-oauth-session-to-make-authenticated-api-calls).

+#   - the request 'Authorization' header as `Bearer this-is-the-session_token`
+#   - or as a URL param `id_token=this-is-the-session_token`
