Store Admin API and custom external payment methods | Docs

New Features

Introducing a new Admin API store retrieve endpoint to retrieve store information such as the public contact information, available languages, available currencies, and primary domain to open up new and deeper integration possibilities.
Custom external payment methods can now be created in the dashboard and used in the Checkout Flow and Admin API when creating a new order to support custom payment methods that dont have native integration.
Disputes now have new status accepted available, and now support adding notes to Disputes on the Admin API, enabling dispute integration providers to add notes.
Klaviyo App now supports setting a default email subscribe list, and uses remote dropdown lists for an improved user experience when configuring the App.

Braintree payment gateway now supports descriptor_name, descriptor_phone, and descriptor_url custom fields, enabling merchants to customize them.
Storefront themes have been updated to use the object meta title in the <title></title>.
Order invoices and store notifications now use the store legal name as it's more appropriate in these cases than the public store name.
Products Admin API now features a sku to enable searching for existing products by their SKU.
We've improved the Admin API and Checkout Flow to validate cases an attempt is made to create a 0.00 (free) initial order with a paid recurring subscription.
We've now remapped the NO_AVAILABLE_PROCESSORS error code from Bluesnap to 5007 as it means the merchant account has been disabled at Bluesnap.
Campaigns App now dynamically shows the available languages and currencies that are configured on the store for a tighter integration.
Campaigns App - improved the campaign edit view to set the campaign currency field as read-only, as it cannot be changed after it's been created.
Improved API integration to always provide the end customer ip_address and user_agent so these can be used for order and payment processing.
