# Buy from Costcovia API

Programmatically buy from Costco's online store. Access bulk products, electronics, and groceries through Zinc's API.

## How the Costco integration works

Costco is America's largest membership warehouse club, known for bulk pricing on groceries, electronics, home goods, health products, and more. Zinc's Costco integration enables automated purchasing from their online catalog at warehouse club prices.

Great for businesses looking to automate bulk procurement, rewards programs that want to offer premium products at competitive prices, and platforms that serve cost-conscious consumers.

### Costco Order Placement API

Place orders with a product URL and shipping address. No checkout flows required — Zinc handles the retailer-side workflow and processes orders asynchronously.
