| 0 | IAP_RESPONSE_RESULT_OK | Success. | N/A |
| 1001880005 | IAP_APP_IAP_NOT_ACTIVATED | The IAP service is not enabled. | Enable the IAP service in AppGallery Connect. |
| 1001880006 | IAP_RESPONSE_RESULT_ERROR | A critical error occurs during API operations. | Fix the error based on the error information in the response. |
| 1001880008 | IAP_RESPONSE_RESULT_ITEM_NOT_OWNED | Acknowledging the delivery failed because the user does not own the product. | Ensure that the product has been successfully purchased and the input parameters of the APIs are correct. Then call the APIs for querying and acknowledging delivery. |
| 1001880009 | IAP_RESPONSE_RESULT_ITEM_CONSUMED_OR_ACKNED | Acknowledging the delivery is already complete for a consumable or non-renewable subscription, and no more delivery acknowledgement is allowed. A non-consumable can be purchased only once and delivered only once. | Check why repeated API calls occur and further optimize the project logic. If process check and suggestions are required, contact Huawei technical support. |
| 1001880010 | IAP_RESPONSE_RESULT_HIGHTRISK | The operation is rejected because the user account has a high risk. | Use another account or register a new account if no other account is available. |

| 1001880012 | IAP_RECORD_NOT_EXIST | The order does not exist. Only the latest order of a product can be queried. The order in this query may be a historical order. | Token verification is unnecessary for a historical order under normal circumstances, and IAP Kit only allows for token verification for the latest order of a product. Check your integration process to make sure it complies with that described in the development guide. |
| 1001880020 | IAP_RESPONSE_RESULT_REPEAT_SHIP_CONFIRM | Acknowledging the delivery is already complete for an auto-renewable subscription, and no more delivery acknowledgement is allowed. | Check why repeated API calls occur and further optimize the project logic.
