V2 REST API

BigCommerce’s V2 REST API exposes many endpoints developers can use to programmatically interact with store resources (including webhooks). Some V2 API resources are not yet exposed in the V3 API; however, for resources that are accessible via both APIs, the V3 API is recommended, as it contains performance optimizations as well as a number of other improvements.

V3 REST API

Like the V2 API, BigCommerce’s V3 REST API exposes many endpoints developers can use to programmatically interact with store resources (including server-to-server carts and checkouts for using BigCommerce headlessly). Interactions with the V3 API are very similar to that of the V2 API; however, the V3 API introduces a number of improvements:

• Most tasks can be performed with fewer API calls (for example, a product with variants and custom fields can be created in a single request)
• Each V3 resource includes a meta object, simplifying pagination
• V3 Brands, Categories, Products, and Product Variants expose a metafields resource for use by developers to store custom data.
• V3 API is optimized for performance (in general, data can be sent, received, and processed faster via V3, relative to V2).

Webhooks

Webhooks allow app developers to be notified when specific events occur. Webhooks are managed via the V2 API and are listed separately here for visibility.

Server: api.bigcommerce.com/stores/{store_hash}/v2

Resource	Description	Endpoint
Webhooks	Manage store Webhooks	/hooks

Additional Information: Webhooks Overview

Payment Processing API

Using the Payment Processing API, developers can programmatically process payments through a BigCommerce store’s payment gateway.

Server: payments.bigcommerce.com/stores/{store_hash}

Resource	Description	Endpoint
Payment Processing	Process payments on orders and checkouts	payments.bigcommerce.com/payments

In addition to the payment processing API’s /payments endpoint, there are two v3 API endpoints related to payment processing. The first (/v3/payments/access_tokens) is required to retrieve a payment access token for authenticating requests against payments.bigcommerce.com. Requests to the second endpoint (/v3/payments/methods) are optional, and can be used to retrieve an order’s accepted payment methods, when necessary.

Request	Endpoint
Create the payment token	api.bigcommerce.com/stores/{store_hash}}/v3/payments/access_tokens
Get order accepted payment methods	api.bigcommerce.com/stores/{store_hash}/v3/payments/methods

Additional Information: Payment Processing API Overview

Storefront API

BigCommerce’s Storefront API is a client API that exposes storefront data to stencil themes. The Storefront API can be used to manage a shopper’s cart and checkout and fetch order data via client-side JavaScript.

Server: {store_domain}/api/storefront

Resource	Description	Endpoint
Storefront Carts	Create and get carts	/carts
Storefront Checkouts	Create and get checkouts on the front-end	/checkouts
Storefront Orders	Get order data after order is placed	/orders

Additional Information: Storefront Cart and Checkout Overview | Working with Storefront APIs |

Storefront GraphQL API

BigCommerce’s GraphQL Storefront API makes it possible to query storefront data from within a Stencil theme or remote site. This means information previously only available on the back-end via Stencil’s template logic can now be accessed via front-end JavaScript. Additionally, by leveraging the power of GraphQL, data for multiple resources can be returned from a single API call, which simplifies integration and increases performance so that developers can focus on building delightful shopper experiences.

Server: {store_domain}/graphql

GraphQL Explorer

Additional Information: GraphQL Storefront API Overview

Customer Login API

The Customer Login API enables single sign-on (SSO). It allows apps to programmatically log in a storefront customer via /login/token/{token}, where{token} is a JSON Web Token (JWT) containing the parameters for the customer login request, signed by the application’s OAuth client secret.

Server: {store_domain}

Resource	Description	Endpoint
Customer Login	Use JWT & SSO to login a customer	/login/token/{token}

Additional Information: Customers & Subscribers Overview

Current Customer API

Apps that interact dynamically with a BigCommerce storefront and convey information specific to a particular logged-in customer must confirm the customer’s identity within the insecure environment of the customer’s browser.

To address this need, BigCommerce provides a Current Customer endpoint accessibly via client-side JavaScript. This endpoint returns a JWT with identifying details about the customer. The information is signed with an OAuth client secret.

Server: {store_domain}

Resource	Description	Endpoint
Current Customer	Securely identify customer on the front-end	/customer/current.jwt?app_client_id=

Additional Information: Customers & Subscribers Overview

Provider APIs

Provider API references describe endpoints, responses, and requests that can be implemented by partners and consumed by BigCommerce for the purpose of creating custom integrations (ex: custom shipping carrier rates via /rates).

Server: {providers_server}

Provider API	Description
Shipping Provider API	Allows third parties to integrate their own shipping carriers into the BigCommerce checkout and control panel.

Additional Information: Shipping Provider API Overview

Add to Cart URLs

Query string parameters can be appended to BigCommerce product and /cart.php URLs in order to pre-select an SKU or add a product to cart. These parameters make it possible to build custom add to cart links and forms for use on BigCommerce storefronts and remote sites (such as WordPress, blog posts, and social media).

Server: {store_domain}

Type	Parameter	Description	Example
string	action=	add or buy; buy goes directly to checkout	/cart.php?action=add&product_id=123
string	couponcode=	coupon code to apply to the cart	/cart.php?action=add&product_id=123&couponcode=10off100
int	product_id=	product id to add to the cart	/cart.php?action=add&product_id=123
int	qty=	quantity to add to the cart	/cart.php?action=add&product_id=123&qty=3
string	sku=	SKU to add to the cart (or select on product page)	/cart.php?action=add&sku=xlredtshirt
string	source=	source of the sale for analytics; can be any string	/cart.php?action=buy&sku=xlredtshirt&source=emailcampaign

Deprecations and Sunsets

This section contains a continuously updated list of deprecated and sunset BigCommerce API endpoints and suggested alternatives.

Deprecations

Deprecated endpoints are no longer supported by BigCommerce and their use is discouraged. New or substitute endpoints should be used instead.

Sunsets

Sunset endpoints will be phased out and removed from the API. Once sunset, the endpoints will no longer be available.

V2 API

Deprecated V2 API Endpoints and V3 API Alternatives

Endpoint	Alternative
/v2/brands	/v3/catalog/brands
/v2/categories	/v3/catalog/categories
/v2/customers	/v3/customers
/v2/options	In V3, options and modifiers are attached directly to the product. Use options and modifiers together to access the contents of the former V2 options response.
/v2/option_sets	option_sets endpoint is not available in the V3 API.
/v2/products	/v3/catalog/products
/v2/redirects/	/v3/storefront/redirects

V2 Sunsets

Endpoint	Date of Deactivation	Alternative
DELETE /v2/customers	May 10, 2020	DELETE /v3/customers
