For Agents
Process eBay orders post-checkout - read order detail, create shipping fulfillments with tracking, issue refunds, and manage buyer payment disputes. 15 endpoints, user-context only.
Use for: Get all unshipped orders from the last 7 days, Mark order ID 12-34567-89012 as shipped with USPS tracking number 9400111234567890123456, Issue a 50% refund for order 02-12345-67890 because the item arrived damaged, Search payment disputes with status OPEN on EBAY_US
Not supported: Does not handle listing creation, payment processing, or buyer-side search - use for post-checkout order processing, shipping, refunds, and payment-dispute resolution only.
The eBay Sell Fulfillment API is where sellers complete the post-checkout half of the transaction - read placed orders, create shipping fulfillments with tracking numbers, issue refunds, and manage payment disputes including evidence upload, contest, and accept actions. The 15 endpoints split across two resources: /order for the order lifecycle and /payment_dispute for buyer-initiated disputes. All operations require a User access token in the seller's context.
Install Jentic One Beta
Connect the Sell Fulfillment API to your agent
Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Sell Fulfillment API, or any other public or private API you need. You set the rules, the agent never sees your credentials, and every call is logged.
Two steps, two machines. Install the instance in a safe environment, then register your agent from wherever it runs.

Step 1: Jentic One Host machine
# On the machine that will host your Jentic One instance:
curl -fsSL "https://jentic.com/install.sh?src=apis&api=%2Fapis%2Febay.com%2Fsell-fulfillment" | sh2
Step 2: Agent machine
# On the machine where your agent runs (keep this separate from the instance):
curl -fsSL "https://jentic.com/install.sh?src=apis&api=%2Fapis%2Febay.com%2Fsell-fulfillment" | sh
jentic register # connects your agent to your Jentic One instanceJentic One is in public beta. The setup above keeps your agent separate from the instance, which is what you want before using real credentials: an agent running as the same OS user as Jentic One can read its stored keys directly. Just evaluating? A single local install is fine to start. See the secure deployment guide for the tiers.
Capabilities
What an agent can do with Sell Fulfillment API.
Read placed-order detail including buyer, line items, shipping address, and totals
Create a shipping fulfillment with carrier and tracking number to mark an order as shipped
Issue a refund (full or partial) for an order via POST /order/{order_id}/issue_refund
Search payment disputes by status, date range, or order ID
Contest, accept, or upload evidence for a buyer-initiated payment dispute
Read a payment dispute's activity log and evidence files for audit trails
Filter orders by status (UNSHIPPED, SHIPPED, COMPLETED) for fulfillment dashboards
Use Cases
Patterns agents use Sell Fulfillment API for, with concrete tasks.
★ Shipping-tracking sync from a 3PL
When a 3PL warehouse ships an order, its system POSTs to /order/{orderId}/shipping_fulfillment with the carrier code, tracking number, and the line items included in that shipment. eBay then notifies the buyer with tracking and updates the order to SHIPPED. Multi-shipment orders are handled by issuing one shipping_fulfillment per package.
POST /order/{orderId}/shipping_fulfillment with carrierCode='USPS', trackingNumber='9400...', and the lineItems array shipped in this package
Damage refund automation
Customer-service tools handle damage-claim refunds by calling /order/{order_id}/issue_refund with the agreed amount and a reasonCode (typically BUYER_RETURN). The endpoint accepts partial refunds, so the tool can reproduce a 'keep the item, refund 50%' agreement without an agent manually navigating eBay's web UI.
POST /order/{order_id}/issue_refund with amount={value:25.00,currency:'USD'} and reasonCode=BUYER_RETURN
Payment dispute response workflow
When a buyer files a payment dispute, the seller's tool reads the dispute via GET /payment_dispute/{payment_dispute_id} plus its activity log and evidence files. If the seller has shipping evidence, the tool POSTs to /payment_dispute/{payment_dispute_id}/upload_evidence_file followed by /add_evidence and /contest. If the seller agrees with the buyer, /accept resolves the dispute in the buyer's favour without further action.
Get payment dispute 5004, upload the proof-of-delivery PDF via /upload_evidence_file, attach via /add_evidence, then call /contest with reason 'item delivered'
Order dashboard for a multi-channel SaaS
Multi-channel seller dashboards poll GET /order with filter 'orderfulfillmentstatus:{NOT_STARTED}' to surface unshipped eBay orders alongside the seller's other marketplaces. Drilling into an order calls GET /order/{orderId} for full detail, including the buyer's shipping address and any charity attribution on the line items.
Call /order with filter='orderfulfillmentstatus:{NOT_STARTED}' and limit=50, then for each id call /order/{orderId}
AI agent integration via Jentic
An AI agent that handles a seller's customer service searches Jentic for 'issue an eBay refund'. Jentic returns POST /order/{order_id}/issue_refund with its required schema. The agent loads the schema, executes the call with a User access token issued through Jentic's vault, and the refund posts to the buyer without the agent storing the seller's refresh token.
Use Jentic to search 'issue an eBay refund', load POST /order/{order_id}/issue_refund, and execute it with the order ID and refund amount

What agents get from Jentic-routed access to this vendor.
Setup
Wiring the eBay Sell Fulfillment API by hand means implementing eBay's OAuth 2.0 authorization-code flow for a seller user token, refreshing it, and pointing requests at the api.ebay.com sell/fulfillment host across order, shipping, and dispute endpoints. Through Jentic you install once, import the Sell Fulfillment API from the API Directory, store the eBay OAuth credentials once, and your agent calls it.
Permission scoping
Fulfillment operations put the resource id in the URL path, such as /order/{orderId} and /payment_dispute/{payment_dispute_id}, so a rule can pin your agent to one order or one dispute. You choose the operations it may call, so a shipping agent gets order reads and shipping_fulfillment while refunds and dispute contests are not included unless you add them.
Credential isolation
Your eBay OAuth seller credentials are stored once, encrypted, by your own Jentic One instance and injected at execution time. They never enter the agent's prompt, logs, or context.
Intent-based discovery
Agents search Jentic by intent such as 'mark an eBay order shipped' or 'issue an eBay refund', and Jentic returns the matching /order or /payment_dispute operation with its input schema so the agent calls the right endpoint without browsing the reference docs.

FAQs
Specific to using Sell Fulfillment API through Jentic.
What authentication does the Sell Fulfillment API use?
The Sell Fulfillment API uses OAuth 2.0 with the Authorization Code grant - every endpoint operates in the seller's context, so a User access token is required. Through Jentic, the seller's refresh token sits in your Jentic One instance and the agent receives a scoped access token for the sell.fulfillment scope only.
Can I issue a partial refund through the Sell Fulfillment API?
Yes. POST /order/{order_id}/issue_refund with an amount object specifying the refund value and currency, plus a reasonCode (e.g., BUYER_RETURN). Pass less than the order total to issue a partial refund. The endpoint requires an explicit reason - there is no zero-context refund path.
What are the rate limits for the Sell Fulfillment API?
Sell Fulfillment falls under the Sell APIs user-context daily quota issued per application-and-user pair. Call /user_rate_limit on the Developer Analytics API and inspect the sell.fulfillment entry to read the live remaining count for the authenticated seller.
How do I mark an order shipped through Jentic?
Search Jentic for 'mark eBay order shipped with tracking', load POST /order/{orderId}/shipping_fulfillment, and execute it with carrierCode, trackingNumber, and the lineItems shipped. Install with pip install jentic. Get started with Jentic One, the self-hosted execution layer.
Can I respond to payment disputes programmatically?
Yes. /payment_dispute exposes /contest, /accept, /upload_evidence_file, /add_evidence, and /update_evidence so a seller's tool can run the entire response workflow - pull the dispute, upload proof of delivery or refund, attach it as evidence, and contest - all without using the eBay web UI.
How do I find unshipped orders only?
Call GET /order with filter='orderfulfillmentstatus:{NOT_STARTED}' to return orders that have no shipping fulfillment yet. Combine with creationdate filters to limit to recent windows for dashboard refresh jobs.
Can I limit what my agent is allowed to do with the eBay Fulfillment API?
Yes. Because you run Jentic One yourself, your own rules decide which operations and credentials the agent may use, so you can grant a shipping agent only order reads and POST /order/{orderId}/shipping_fulfillment while leaving out issue_refund and payment-dispute actions like contest and accept unless you add them. Since the resource id sits in the URL path, such as /order/{orderId} and /payment_dispute/{payment_dispute_id}, you can also pin the agent to a single order or dispute. Your eBay OAuth seller credentials stay in your own instance and are injected only at execution time, never entering the agent's prompt or logs.
