About Our APIs

Want to get started making API Requests right away? Check out the Quick Start.

The BigCommerce set of APIs allows you to create apps, automate store processes, or build headless ecommerce solutions. Need inspiration on what to build? Visit our App Marketplace.

Available APIs

BigCommerce has several different APIs that let you manage store data, authenticate customers, make client-side queries for product information, and more.

REST APIs (V2 & V3)

BigCommerce’s REST APIs (for example, the Catalog API) allow you to manage store data and take actions that mimic store administrator activity. Some example uses of the REST APIs are:

  • Add and update products in a store
  • Update a customer’s order and change the order status
  • Create a coupon
  • Manage a customer’s store account details

Storefront API

The Storefront API allows you to manage customer carts and checkouts and order information client-side. Some example uses of the Storefront API are:

  • Add an item with Javascript to a shopper’s cart from the Storefront
  • Programmatically retrieve and display information to a customer about their recent order
  • Update the billing address of a checkout
  • Clear a customer’s current cart


BigCommerce’s GraphQL API allows you to query product and customer data and store settings remotely or from a store’s front end. Some use-case examples are:

  • Pull a product’s data with Javascript into a Stencil theme
  • Access customer data via the front end of a site
  • Fetch category and brand details from a store’s front end

Customer Login API

The Customer Login API lets you programmatically log in customers to a BigCommerce storefront. Some example uses of this API are:

  • Log in customers to a BigCommerce store via a third-party system
  • Enable login using credentials other than email and password (i.e., using a phone number)
  • Integrate a BigCommerce store with an SSO provider

Current Customer API

BigCommerce’s Current Customer API allows you to determine which customer is logged in to a storefront during a session.

  • Confirm a customer’s identity in the browser
  • Validate a customer’s identity to display specific information to them from an external app

API environments

Make BigCommerce API requests in the context of the storefront or server-to-server.

Storefront API{endpoint}
GraphQL https://www.{bigcommerce_storefront_domain}.com/graphql
Customer Login https://www.{bigcommerce_storefront_domain}.com/login/token/{token}
Current Customer /customer/current.jwt?app_client_id={app_client_id}

REST API (V2 & V3)

Request Headers

Server-to-Server request headers require Accept, X-Auth-Token, and Content-Type at a minimum.

Header Allowed Values Description Example
Accept application/json (for .json requests) application/xml (for .xml requests) The MIME type format for receiving a response. application/xml
Content-Type application/json (for JSON requests) application/xml (for XML requests) The MIME type of the request body. Used to validate and parse the request to the API. application/json
User-Agent String While it is not required, we ask that you specify a user agent which identifies your integration/client with your requests.
X-Auth-Token String Access token authorizing the app to access resources on behalf of a user.

Response headers

Header Possible Values Description Example
Date An RFC 2822 date. The date the response was sent. Tue, 15 Nov 2011 12:45:26 GMT
last-modified An RFC 2822 date. The date the resource was last modified. Please refer to the individual resource pages for support for this header. Tue, 15 Nov 2011 12:45:26 GMT
Content-Type application/json The MIME type of the response, dependent on the extension of the endpoint that was requested. application/json
Content-Location A URI Sent if the request was redirected. /api/v2/orders/5.json
Location A URI The URI of a newly created resource. Sent with a 201 Created response. /api/v2/products/7
X-Retry-After integer Rate limited response, indicating the number of seconds before the quota refreshes. See Rate Limits for more information. 15
X-BC-ApiLimit-Remaining integer The number of API requests remaining for the current period (rolling one hour). See Rate Limits for more information. 987
X-BC-Store-Version A version number The version of BigCommerce on which the store is running. This header is available on versions 7.3.6+. 7.3.6
Content-Encoding gzip Allows API clients to request content to be compressed before being sent back in the response to an API request. gzip
Transfer-Encoding chunked Specifies the form of encoding used to transfer the resource. chunked
X-Rate-Limit-Requests-Left number Details how many remaining requests your client can make in the current window before being rate-limited. In this case, you would expect to be able to make 6 more requests in the next 3000 milliseconds; on the 7th request within 3000 milliseconds, you would be rate-limited and would receive an HTTP 429 response. 16101491
X-Rate-Limit-Requests-Quota number Shows how many API requests are allowed in the current window for your client. 16101495
X-Rate-Limit-Time-Reset-Ms number Shows how many milliseconds are remaining in the window. In this case, 3000 milliseconds – so, 3000 milliseconds after this request, the API quota will be refreshed. 30000
X-Rate-Limit-Time-Window-Ms number Shows the size of your current rate-limiting window. 9762

Media types

A media type is the format of the request or response body. The BigCommerce API accepts requests and responds in JSON. You should encode requests using the UTF-8 character set (other character sets might have unpredictable results).

Content types

Request content type

When performing a request that contains a body (eg. POST or PUT), the type of content you are sending needs to be specified in the Content-Type header.

Response content Type

There are two ways you can specify the type of content you would like to receive. The first method is to specify an Accept header. The second is to supply an extension to the resource you are requesting.

The priority in which you can process these methods are:

  • Accept header high-priority types (eg. Accept: application/json) extensions on the resource (e.g. customers.json).
  • Accept header low priority types (priorities less than 1, e.g. Accept: application/json;q=0.9)

Request Structure

The body of a JSON request is an object containing a set of key-value pairs. A simple representation of a product object is:

 "id": 5,
 "name": "iPod",
 "description": "A portable MP3 music player."

Response structure

Responses are structured similarly to requests. If a request returns a single object, then the response will contain a single object containing the fields for that resource.

Response Get a category /GET{store_hash}/v3/catalog/categories/{category_id}

  "data": {
    "id": 39,
    "parent_id": 19,
    "name": "Bath",
    "description": "",
    "views": 0,
    "sort_order": 0,
    "page_title": "",
    "meta_keywords": [
    "meta_description": "",
    "layout_file": "category.html",
    "image_url": "",
    "is_visible": true,
    "search_keywords": "",
    "default_product_sort": "use_store_settings",
    "custom_url": {
      "url": "/garden/bath/",
      "is_customized": false
  "meta": {}
