Brand dealer portal
Mizuno B2B API
Bridge to Brands reads live warehouse availability, dealer price and retail price from the Mizuno USA B2B portal and places fill-in orders within your limits (placed from Bridge until verified) through one normalized REST API and MCP server. Availability is returned per colourway, by size and delivery window. Drop-ship is not offered for this brand in v1.
An agent connected to Bridge to Brands can look up Mizuno items by SKU, UPC or style, read live availability and price, and place a fill-in order within your limits — or, until the brand is verified for placing, stage it for you to review and place in Bridge.
About the Mizuno USA B2B portal
Mizuno sells running footwear to independent retailers through the Mizuno USA B2B portal. Buyers use it to check what is in the warehouse now, what lands in later delivery windows, and what each colourway costs at dealer and retail price.
Bridge to Brands signs in to that portal with your store’s own Mizuno dealer login (entered once in the web app, never through an API key) and turns it into the same normalized products, availability grids, ship-tos and orders every other brand returns. Your agents, code and spreadsheets do not need to know how the Mizuno portal is built.
Portal: b2b.mizunousa.com
What we read and stage
| Live availability (at-once and future windows) | Yes |
|---|---|
| Dealer and retail price | Yes |
| Width as a size axis | No |
| Bulk lookup by UPC / SKU / style (200 per call) | Yes |
| Search | By SKU, UPC or style |
| Fill-in orders to your ship-tos | Yes |
| Drop-ship to a consumer | No (ship-to set at checkout) |

| Store email required for drop-ship | No |
| PO number length | Checked against the portal before ordering |
| Order placing | Partly built — needs a recorded portal session |
| Confirmations & tracking | Not yet |
Order placing turns on per brand only after a logged live test on a real account (and, where marked, the brand’s written permission); until then every order is staged, and you review it and place it in Bridge through a signed-in portal window — no portal login. Confirmations & tracking say “Verified” only after a logged read-only live run.

}Mizuno B2B API: questions
Does Mizuno have a B2B API for retailers?
As of 16 October 2026, Bridge to Brands gives authorized Mizuno dealers API and agent access to their own account: we connect to the Mizuno USA B2B portal with the store's dealer login and expose availability, dealer and retail price and fill-in ordering through a normalized REST API and an MCP server.
Can I check Mizuno wholesale availability by API?
Yes. As of 16 October 2026, GET /v1/brands/mizuno/products/{style_id}/availability returns the Mizuno availability grid per colourway: size columns by delivery window (at-once), with quantities as the portal shows them, order limits, dealer and retail price, and an as_of timestamp.
Can I place Mizuno drop-ship orders through an API?
Not in v1. As of 16 October 2026, Bridge to Brands orders Mizuno fill-ins only to your own store ship-tos and does not offer drop-ship for this brand.
Does Bridge to Brands place Mizuno orders in the portal?
As of 16 October 2026, Bridge to Brands places Mizuno orders in the Mizuno USA B2B portal where the brand's submit path is verified and you have turned it on, within your caps and confirmation settings. Mizuno is not yet verified for submit, so orders come back as staged_in_portal: you review the basket in Bridge and place it in a signed-in portal window there, with no portal login.
Can Claude or ChatGPT use my Mizuno dealer account?
Yes, through the Bridge to Brands MCP server at https://mcp.brdg2b.ai/mcp. As of 16 October 2026, Claude connects with an API key or OAuth and ChatGPT with OAuth; tools such as get_availability and place_order act on Mizuno with the key's scopes, and every call is metered to that key.
Can I search the Mizuno catalog by API?
As of 16 October 2026, Mizuno has no free-text search in Bridge to Brands; find items by SKU, UPC or style with POST /v1/brands/mizuno/lookup or the MCP tool lookup_items, then read availability per style.
Can Bridge to Brands place Mizuno orders for me?
As of 16 October 2026: Placing Mizuno orders is partly built: a portal step still needs a recorded portal session, so orders are staged and you review and place them in Bridge, in a signed-in portal window with no portal login.
Does Bridge to Brands return Mizuno order confirmations and tracking?
As of 16 October 2026, not yet: Bridge to Brands does not read Mizuno confirmations or tracking, so check order status in the Mizuno USA B2B portal.
