Shopify B2B Integration

Hi everyone,
I’m working on an app that currently supports Shopify and Shopify Plus stores, and I’m exploring how to extend it to include Shopify B2B features.
I’d appreciate some clarification on a few points:

  1. Can third-party apps integrate with Shopify B2B environments and access native B2B features such as companies, price lists, and payment terms through the available APIs?

  2. Is Shopify B2B available only for Shopify Plus merchants, or can standard Shopify merchants also use it?

  3. Are there any API restrictions or special considerations to be aware of when adding B2B support?

I want to make sure the integration aligns fully with Shopify’s current B2B capabilities and best practices.
Thanks in advance for any guidance or insights!

B2B is plus only.

I suggest having a read of these docs for API options → Manage B2B catalogs
