Multiple payment methods

Whether you have a gift card or a credit card, the Zinc API provides multiple ways to purchase your items. On any of our supported retailers, including Amazon and AliExpress, you can use the gift balance on your account or provide a credit card for your order.

If you leverage our managed accounts, we can provide even more funding methods including PayPal, ACH, and even Bitcoin.

Maximum price criteria

Product prices fluctuate, sometimes wildly. With Zinc, you'll never have to worry about accidentally placing an incredibly costly order.

You can set a maximum fulfillable price on an order to the Zinc API. An error will be returned if the price of the order is above the maximum price.

Realtime product and price information

Get up to date information on every imaginable detail about a product.

The product prices request provides price, seller information, shipping price, and more for every seller of a particular item.

The product details request provides descriptions and variant information (like color and size) for a product.

Tracking Through Delivery

Get up to date information about where your order is and when it will arrive.

The API will provide you with a tracking number and URL even for orders generally not publicly trackable.

Receive updates when the status of your automatic order changes so you can notify customers, handle disputes, etc.

Leverage managed accounts

Scale Endlessly

Retailers including Amazon and Walmart often limit the number of orders you can place per account and the quantity you can purchase of a particular item. Free yourself from all order rate limits with Managed Accounts!

Easier Integration

A lot of the hassle around using your own retailer account is related to payment and login. Managed accounts remove those hassles and significantly simplify integration.

Fund easily with PayPal, ACH/wire, and more, in USD, EUR, Bitcoin, etc.

Depending on your business requirements, ordering via credit card will hit limits, funding with gift cards can be a chore, and transferring between financial institutions can be a hassle. Often such conversions require a lot of working capital. Easily fund your Zinc Managed Account using a variety of payment methods and we take care of the rest.

Resale Certificates

If you're purchasing for resale and not subject to sales tax, getting the required certificates and registering them for each retailer account you wish to purchase from takes a long time. We'll help you register your tax exempt reseller status with us once and we'll take care of the rest.
