Components of Rye ecosystem

eCommerce concepts


Refers to items listed on merchants’ inventory. However, product variant must be specified to place an order, e.g. size and color of product. Each product_variant is associated with a unique id.


Product data and meta data supplied by merchants, including price, image, and stock availability. Rye has an up-to-date database that developers can pull from using the Sell Anything API.


A cart contains one or more product_variant. Rye supports carts with items from multiple merchants, hosted on multiple eCommerce building platforms. The whole cart is submitted when an order is placed


Payment processing for the items in cart. Rye supports a native checkout experience (no need to redirect to individual merchant sites) using most payment methods (see more on Rye Pay).


Rye programmatically sends orders to merchants and returns an order_id.


Gross merchandise value, refers to the total value of goods exchanged on the platform. This excludes add-ons such as shipping and tax.

Developer monetization

Developers have 2 ways to monetize with Rye: adding a % markup on MSRP or getting a % commission of the GMV of each sale.

Commission rate

% of the GMV as a reward for the platform that facilitated the sale. Developers can specify a set commission rate with merchants they have an existing relationship with. Merchants that integrate directly with Rye are able to set a custom commission rate. Developers are likely to prioritise products with higher commission rates.

Shipping details

A valid shipping method and shipping address must be submitted for an order to be successfully placed and fulfilled. Shipping options are defined by merchants, which sometimes use third-party logistics (3PL) providers.


B2B services (mostly commonly in the form of Shopify apps) that facilitate the eCommerce experience, e.g. loyalty and reward programmes, order tracking, bundles and upsell. Rye has a Shopify app for merchants to plug into.


A method to notify one system about updates in an external system. Rye has webhooks that send real-time updates such as order placed, order failed, and tracking info.
