Marketplace Sync Troubleshooting

Diagnose connection, webhook, queue, SKU mapping, stock and fulfilment problems without corrupting local inventory.

Blank/failed connection

Check HTTPS URL, DNS, SSL, credentials and seller approval. Run Test Connection and read the exact error log.

401 token error

Refresh or reconnect access token; verify client ID/secret and expiry.

403 scope error

Enable the required role/scope in the marketplace developer portal.

No orders imported

Check automatic orders toggle, webhook status, queue jobs and the incremental cursor.

SKU unmapped

Open Product / SKU Mapping and map seller SKU to the correct product variant.

Stock mismatch

Verify warehouse mapping, reservations, safety buffer and deduction stage.

Webhook rejected

Verify secret/signature, timestamp, HTTPS and callback URL.

Queue stuck

Run Sync Now; stale locks older than 20 minutes reset automatically.

Duplicate order

Existing idempotency keys and order-item unique keys prevent a second stock deduction.
