What Fourthwall (BYOK) is for

Fourthwall (BYOK) lets an AI assistant read your own Fourthwall data through the Fourthwall API with a key you supply (Open API username). Read-only: 12 tools (get_shop, list_products, get_product, get_product_inventory, list_collections, list_collection_products, list_orders, get_order, list_donations, list_membership_tiers, list_members, list_promotions). The BYOK key travels with each request, is used for that one call only and is never stored, logged or cached; it is only ever sent to api.fourthwall.com. Unofficial connector by Unify Dynamics LLC: not affiliated with, endorsed by or sponsored by Fourthwall. Fourthwall and its logos are trademarks of their owners and are used only to say which service the connector works with.

Ask your assistant things like:

  • "Which Fourthwall shop is my API user connected to?"
  • "What products do I have in my Fourthwall shop?"
  • "Show Fourthwall product prod_example"
  • "How much stock is left for each variant of Fourthwall product prod_example?"
  • "What collections does my Fourthwall shop have?"
  • "Which products are in Fourthwall collection col_example?"

What it does

  • get_shop: Show the Fourthwall shop the API user belongs to: name, domain, public domain and status.
  • list_products: List shop products with name, slug, description, type, state and access, optionally filtered by search text.
  • get_product: Get one product by ID: name, slug, description, type, state, access and dates.

  • list_collections: List the shop's product collections with name, slug, description and availability.
  • list_collection_products: List the products in one collection, optionally filtered by product status.
  • list_orders: List shop orders with status, supporter display name, message, amounts (subtotal, shipping, tax, donation, discount, total) and dates. Customer email and addresses are not returned.
  • get_order: Get one order by ID: status, supporter display name, message, amounts and dates (no email or addresses).
  • list_donations: List donations with status, supporter display name, message, amounts and dates (no email).
  • list_membership_tiers: List membership tiers with name and their monthly or annual price variants.
  • list_members: List members with nickname, join date and subscription (tier variant). Email addresses are not returned.
  • list_promotions: List promotions and discount codes with title, code, status, usage count and limits.

BYOK key

You bring your own Fourthwall Open API username (https://docs.fourthwall.com/guides/authentication). Your assistant sends it in the X-Upstream-Key header with each request. ConnectorBay uses it for that one call only: it is never stored, logged or cached, never shown in an answer, and it is only sent to api.fourthwall.com over https, with no redirects followed. Create a key with the fewest permissions the tools need (read-only if the provider offers it), and revoke it at the provider whenever you like.

Data sources

Live from the Fourthwall API (api.fourthwall.com) with a BYOK key; documentation: https://docs.fourthwall.com/api-reference/platform/shop/get-current-shop. Endpoints checked against that documentation on 2026-10-16.
