Checkout
This is the primary Calypso section for making a new purchase or manual renewal for WordPress.com, Jetpack, and Akismet.
For the most part, Checkout consists of the Shopping Cart data layer (via the @automattic/shopping-cart package), and the Checkout view in this section. The shopping cart handles all of the product logic and validation.
Initializing Checkout flow
To start Checkout, you can either visit Checkout directly (https://wordpress.com/checkout/site.wordpress.com/) with an item already added to the shopping cart, or you can initialize Checkout with the required site and product data passed directly via url (https://wordpress.com/checkout/{site_slug_or_id}/{product_slug}).
Examples:
https://wordpress.com/checkout/site.wordpress.com/premiumhttps://wordpress.com/checkout/site.wordpress.com/personalhttps://wordpress.com/checkout/site.jetpack.me/premiumhttps://wordpress.com/checkout/site.jetpack.me/professional
Product slugs are sourced from the constants in @automattic/calypso-products. Some product slug aliases exist (e.g. value_bundle -> premium), and can be set via the path_slug value in Store_Product_List.
Multiple products can be passed as comma-separated slugs. Some products (e.g. domain registrations) require meta to be passed in the url via a colon separator. Similarly, quantities for a product can be specified with the :-q-{quantity} pattern.
Example:
https://wordpress.com/checkout/example.wordpress.com/personal,domain_reg:example.com,wp_google_workspace_business_starter_yearly:example.com:-q-12
