LinkYour users. Their accounts.
Buy anywhere online.
Zinc Link is an SDK that connects the retailer accounts your customers already have and buys on their behalf: their prices, their memberships, their rewards.

Buy as them, not for them
A card on file gets the item to the door. Their own account gets the discounts, the memberships and the history they have already built up.
Their memberships
Their memberships, their rewards
Prime, Walmart+, Circle 360, and an Executive card. Link checks out the way they would, so the free shipping, the member prices, and the points on their own card all still land.
Home DepotPro Xtra$7.98Their terms
Their negotiated prices
Pro Xtra pricing, a Grainger contract, Net 30 on the Uline account. Those terms live on the account, not on the product, and buying on that account is the only way to get them.
Their login
Their sign-in, handled
They sign in once. Passwords stored encrypted, verification codes captured and entered, sessions kept warm. The login is never your customer’s problem, or yours.
The checkout is the easy part
A browser agent given a prompt clicks until something happens. Zinc Link is a typed SDK: what an order is allowed to be is stated up front and checked before it is placed, and everything after checkout is a call away.
Install the SDK.
We handle the rest.
The sophisticated part is ours: the sign-ins, the codes, the proxies, the checkout itself. Yours is one install on web, iOS or Android.
They sign in once, in a Zinc-hosted sheet. Your app never sees the password.

What will you build?
Point-and-click buying is becoming agentic buying. Use Zinc Link as the bedrock. Three things you could build on it:

Photograph it, reorder it
Your app recognises what is in the photo. Link prices every line on the contractor’s own Home Depot Pro account and buys the lot.

The dress from last night’s episode
Your assistant works out which dress. Link finds it and buys it on their account, and when Amazon is out, from the store that is not.

Your dashboard, their websites
Your purchasing dashboard runs the company’s buying. Zinc Link is the layer underneath, placing each order on the supplier’s own site.
Book a call. We are onboarding teams directly and will walk you through what Link can do for your product before anything is installed.
No. Credentials are entered in the Zinc-hosted sheet, encrypted at rest and used only by Zinc's checkout automation. Your app receives an account ID and a token it can revoke, nothing else.
Link has more than one way through a retailer's sign-in and verification steps, and uses whichever keeps the purchase moving. Your customer is only asked to do something when there is genuinely no other way, and then only once.
Any retailer with a web checkout. Link is built around the stores your customers already buy from: the big general retailers, the trade and industrial suppliers, the specialists. New ones are added as customers need them.
The same lifecycle Zinc runs for every order: tracking pulled from the retailer, delivery confirmation, the invoice captured against the account that bought, and refunds or returns you can start with one call. Each step arrives as a webhook event.
