  title: Negotiation API
  description: 'The <b>Negotiations API</b> gives sellers the ability to proactively send discount offers to buyers who have shown an "interest" in their listings.  <br><br>By sending buyers discount offers on listings where they have shown an interest, sellers can increase the velocity of their sales.  <br><br>There are various ways for a buyer to show <i>interest </i> in a listing. For example, if a buyer adds the listing to their <b>Watch</b> list, or if they add the listing to their shopping cart and later abandon the cart, they are deemed to have shown an interest in the listing.  <br><br>In the offers that sellers send, they can discount their listings by either a percentage off the listing price, or they can set a new discounted price that is lower than the original listing price.  <br><br>For details about how seller offers work, see <a href="/api-docs/sell/static/marketing/offers-to-buyers.html" title="Selling Integration Guide">Sending offers to buyers</a>.'
