Common API errors
Understand common errors like invalid token, missing action, product not found, and duplicate-safe replays.
Authentication errors
- invalid_token means the Authorization Bearer token is wrong or regenerated.
- connection_not_found means the endpoint connection key is wrong.
- connection_paused means the connection is paused in BOS settings.
Payload errors
- missing_action means the JSON does not include action.
- no_valid_products means order.create could not match product_id or SKU.
- missing_contact means customer name or phone is missing.
- order_not_found means the order_id or order_number does not belong to the company.
How to fix
Check the endpoint, Authorization header, JSON action, product SKU, and API logs. For n8n, also check that the HTTP Request node sends JSON body, not form data.
