Seller API
A Seller API is a tool that helps businesses automatically connect their products and inventory to online marketplaces like Amazon, eBay, or Etsy. Think of it as a digital bridge that lets sellers manage their store without manually entering data. Instead of typing in each product detail or updating inventory by hand, the Seller API allows computer systems to do this work automatically. This is especially important for businesses that sell on multiple platforms or handle large numbers of products. It's similar to having a universal remote control that can operate multiple TVs - the Seller API lets businesses control multiple online stores from one place.
