eBay APIs: setup and what it can do Advanced
eBay offers APIs for selling, orders and searching items. Here's what it can do, what you need, and how to get started without being a programmer.
What you'll learn
- What this API is for
- The setup steps, in order
- What it can do for a bot
Before you start
- The Grok Bot app, installed and signed in. New? See where to download it and installing and signing in.
- An account with the service (and, for shipping or selling, a business account).
- Some patience: developer portals look technical, but you only need a few pages.
1. What it is, in plain words
eBay offers APIs for selling, orders and searching items. An API (application programming interface) is a doorway that lets one program ask another for information or to do something. New to APIs? Read What is an API? and API keys vs OAuth first.
2. Why you'd want it
A bot could manage listings, pull orders to ship, or search for comparable items.
3. Set it up
- Join the eBay Developers Program.
- Create Sandbox (test) and Production keysets (App ID and Cert ID).
- Register a redirect (called a RuName).
- Get a user OAuth token with the sell scopes you need. Application tokens reach only public data.
4. What it can do
- Inventory API: listings and offers
- Fulfillment API: orders and shipping
- Browse API: search items
- Account, Finances, Marketing and Analytics APIs
5. Let your bot help
You don't have to write the code yourself. Tell your bot what you want and point it at the official docs:
Read the official eBay APIs docs and show me, step by step, how to get my first test call working. Ask me for keys with a secure form.
When your bot needs a key or secret, let it ask you for it with a secure form, so the value is masked and isn't written into the chat. Never paste keys or passwords into an ordinary message.

Ideas to try
- Reseller.
List my eBay orders awaiting shipment.
- Pricing research.
Search eBay for sold-style comparable listings of this item using the Browse API.
- Listings.
Draft an inventory item for this product; wait for approval.
- Payouts.
Summarize recent payouts from the Finances API.
Tips
- Always start in the test (sandbox) environment if one exists.
- Give keys the smallest permissions that do the job.
- Write down where each key lives so you can replace (rotate) it later.
