eBay (via Apideck)

Access eBay through Apideck's Ecommerce unified API — one of 17 Ecommerce connectors that share the same method surface. Code you write here ports to Shopify, BigCommerce, Shopify (Public App) and 13 other Ecommerce connectors by changing a single serviceId string. Apideck handles auth, pagination, rate limiting, and retries so you don't write per-tenant eBay plumbing.

Beta connector. eBay is currently in beta on Apideck. Expect partial resource coverage and occasional mapping gaps. Always verify coverage (see below) and fall back to the Proxy API for unsupported operations.

Quick facts

• Apideck serviceId: ebay
• Unified API: Ecommerce
• Auth type: oauth2
• Status: beta
• Gotchas: page
• eBay docs: https://developer.ebay.com
• Homepage: https://www.ebay.com/

When to use this skill

Activate this skill when the user explicitly wants to work with eBay — for example, "list orders in eBay" or "sync products in eBay". This skill teaches the agent:

1. Which Apideck unified API covers eBay (Ecommerce)
2. The correct serviceId to pass on every call (ebay)
3. eBay-specific auth and coverage caveats

For the full method surface (parameters, pagination, filtering), use your language SDK skill:

• apideck-node, apideck-python, apideck-dotnet, apideck-java, apideck-go, apideck-php, or apideck-rest

For the raw OpenAPI spec:

• Ecommerce: https://specs.apideck.com/ecommerce.yml · API Explorer

Minimal example (TypeScript)

import { Apideck } from "@apideck/unify";

const apideck = new Apideck({
  apiKey: process.env.APIDECK_API_KEY,
  appId: process.env.APIDECK_APP_ID,
  consumerId: "your-consumer-id",
});

// List orders in eBay
const { data } = await apideck.ecommerce.orders.list({
  serviceId: "ebay",
});

Portable across 17 Ecommerce connectors

The Apideck Ecommerce unified API exposes the same methods for every connector in its catalog. Switching from eBay to another Ecommerce connector is a one-string change — no rewrite, no new SDK.

// Today — eBay
await apideck.ecommerce.orders.list({ serviceId: "ebay" });

// Tomorrow — same code, different connector
await apideck.ecommerce.orders.list({ serviceId: "shopify" });
await apideck.ecommerce.orders.list({ serviceId: "bigcommerce" });

This is the compounding advantage of using Apideck over integrating eBay directly: code against the unified Ecommerce API once, gain access to every connector in it. New connectors Apideck adds become available to your app without code changes.

Authentication

• Type: OAuth 2.0
• Managed by: Apideck Vault — Apideck handles the full OAuth dance (authorization code flow, token exchange, refresh). Never ask the user for API keys or tokens directly.
• User setup: Users authorize via the Vault modal. Connection state progresses available → added → authorized → callable.
• Token refresh: automatic. Expired tokens are refreshed transparently on the next API call.

See apideck-best-practices for Vault setup, connection lifecycle, and handling re-auth flows.

Verifying coverage

Not every Ecommerce operation is supported by every connector. Always verify before assuming a method works:

curl 'https://unify.apideck.com/connector/connectors/ebay' \
  -H "Authorization: Bearer ${APIDECK_API_KEY}" \
  -H "x-apideck-app-id: ${APIDECK_APP_ID}"

See apideck-connector-coverage for patterns around UnsupportedOperationError and connector-specific fallbacks.

Escape hatch: Proxy API

When an endpoint isn't covered by the Ecommerce unified API, use Apideck's Proxy to call eBay directly — Apideck injects auth headers and handles token refresh. Set x-apideck-downstream-url to the target endpoint on eBay's own API:

curl 'https://unify.apideck.com/proxy' \
  -H "Authorization: Bearer ${APIDECK_API_KEY}" \
  -H "x-apideck-app-id: ${APIDECK_APP_ID}" \
  -H "x-apideck-consumer-id: ${CONSUMER_ID}" \
  -H "x-apideck-service-id: ebay" \
  -H "x-apideck-downstream-url: <target endpoint on eBay>" \
  -H "x-apideck-downstream-method: GET"

See eBay's API docs for available endpoints.

Sibling connectors

shopify (beta), bigcommerce (beta), shopify-public-app (beta), woocommerce (beta), amazon-seller-central (beta), etsy (beta), magento (beta), bol-com (beta), and 8 more.
