Etsy Open API v3: setup and what it can do Intermediate

Etsy is a marketplace for handmade and vintage items, and its Open API v3 lets programs work with listings and shop orders. Here's what it can do, what you need, and how to get started without being a programmer.

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

Etsy is a marketplace for handmade and vintage items, and its Open API v3 lets programs work with listings and shop orders. 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 update listings, check new orders (receipts), or manage shipping profiles.

3. Set it up

Register an app on Etsy's developer site to get a keystring and shared secret.
Send the keystring as x-api-key on every call.
For anything about your own shop, use OAuth 2.0 with PKCE (a safer sign-in flow). Public listings need only the key.

4. What it can do

Listings: create, update, images, inventory
Shop details
Receipts (orders) and transactions
Shipping profiles

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 Etsy Open API v3 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

Side hustle.
List my active Etsy listings with price and quantity.
New orders.
Show receipts from the last 3 days that aren't shipped.
Bulk edits.
Draft new titles for my 5 oldest listings; don't change them yet.
Learning.
Explain PKCE in plain words.

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.
