| --------------------------------------- | ------------------------------------------------------ | ------------------------------------------------------------------------------------------------------------------------------------------------ |
| Connection shows Failed                 | Invalid Client ID, Client Secret, or revoked access    | Check your eBay Developer Program app settings. Verify the credentials are correct. Re-authorize by generating a new Authorization Code.         |
| Orders not importing                    | Flow disabled or schedule not set                      | Enable the Order Import flow in IDC. Go to Triggers and set a schedule (hourly is typical). Check the activity log to see if the flow ran.       |
| Orders importing but missing customer   | Customer matching failed                               | Set a Default Customer ID in the Order Import settings, or configure customer matching in field mappings.                                        |
| Fulfillments not updating eBay          | Missing eBay Order ID on Sales Order                   | Verify the Sales Order was imported from eBay. Check that the eBay Order ID custom field is populated. If missing, re-run the Order Import flow. |
| Stock levels not syncing                | Location mapping not configured                        | Go to the Stock tab and add a Stock Mapping for each NetSuite location that should sync to eBay. Verify the SKU Match Field is correct.          |
| Returns not importing                   | Return Authorization flow disabled or schedule not set | Enable the Return Authorization flow and set a schedule. Check the activity log to confirm the flow ran.                                         |
| Settlement reports missing transactions | Transaction import flow not enabled                    | Verify the Payout Transaction Import flow is enabled. Check the activity log for errors.                                                         |

## FAQs

**Why doesn't my Authorization Code work?** Authorization Codes expire quickly—usually within an hour. If you take too long to enter it, generate a new one from eBay's authorization page.

**Can I sync just orders without inventory?** Yes. You can enable only the Order Import, Fulfillment Export, Return, and Settlement flows without touching Item Update or Stock Export. Just disable the inventory flows.

**What if I create offers manually in eBay instead of using IDC?** Leave "Create eBay Offer Automatically?" turned OFF in Item Update settings. IDC will discover your manually-created listings and start syncing stock to them on the next run.

**How often should I schedule flows?** For most use cases, hourly is ideal. Orders and returns arrive throughout the day, and you want them in NetSuite quickly. If you have very light eBay traffic, running every 4 hours is acceptable.

**Does IDC support multiple eBay accounts?** Yes. Install the eBay app multiple times (one per account) in IDC. Each app instance has its own connection, credentials, and flows. They can all flow into the same NetSuite account and same subsidiary, or different subsidiaries if you prefer.

## Still need help?

If your issue isn't listed here, check the [IDC activity log](/idc/idc-core/logs.md) for details on what happened during the last sync. Look for error messages that describe what went wrong. You can also contact In8Sync support from within the IDC dashboard—click **Support** in the left menu.
