Management APIs


Mananage store resources from server-side code.

Some V2 resources are not yet exposed in the V3 API; however, for resources that are accessible via both APIs, the V3 API is recommended; it contains performance optimizations and other improvements.


Mananage store resources from server-side code.

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).

Learn more about the V3 API.

Provider APIs

Implement endpoints consumed by BigCommerce for custom integrations (ex: custom shipping carrier rates via /rates).
