# Code and Formats source: https://developer.mastercard.com/rpps-biller-maintenance-service/documentation/code-and-formats/index.md This section describes errors that the Mastercard gateway or the Remote Payment and Presentment Service (RPPS) Biller Maintenance Service can return. The error format depends on which component generated the error and at what point the request failed: 1. Application error messages are returned by the service and typically occur because of incorrect input. 2. Gateway error codes are returned by the gateway and typically occur when OAuth 1.0a authentication fails. For exact field formats, lengths, and allowed values, see the [API Reference](https://developer.mastercard.com/rpps-biller-maintenance-service/documentation/api-reference/index.md). ### Where Errors Occur {#where-errors-occur} | Endpoint | Workflow step | Typical reason codes | |------------------------------------------------|-------------------------------------------|-------------------------------------------------------------------------------------------| | POST `/biller-request` | Adding, editing, or deactivating a Biller | `BPBMSAPI_ERR_0002` to `BPBMSAPI_ERR_0074` and `BPBMSAPI_ERR_0077` to `BPBMSAPI_ERR_0119` | | GET `/biller/{biller_id}` | Retrieving Biller details before an edit | `BPBMSAPI_ERR_0021` (invalid Biller ID) and `BPBMSAPI_ERR_0072` (no access) | | GET `/biller-request/{work_request_id}/status` | Checking work request status | `BPBMSAPI_ERR_0075` (invalid work request ID) and `BPBMSAPI_ERR_0076` (no access) | Access errors (`BPBMSAPI_ERR_0071`, `BPBMSAPI_ERR_0072`, and `BPBMSAPI_ERR_0076`) return HTTP `403` and are not recoverable by changing the request. All other service errors return HTTP `400`. Correct the request as described in **How to Resolve** and resubmit it. ### Error Structure {#error-structure} Mastercard returns errors in the following structure. ```json { "Errors": { "Error": [ { "Source": "", "ReasonCode": "", "Description": "", "Recoverable": true/false, "Details": "" } ] } } ``` ## HTTP Response and Reason Codes {#http-response-and-reason-codes} ### Service Error Codes {#service-error-codes} The **Description** column shows the message text that the service returns in the `Details` field. | **Error/Reason Code** | **HTTP Code** | **Description** | **How to Resolve** | |-----------------------|---------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | BPBMSAPI_ERR_0000 | 400 | Internal Server Error, please contact support for help | Contact Support | | BPBMSAPI_ERR_0001 | 400 | No Request Mapping found | Contact Support | | BPBMSAPI_ERR_0002 | 400 | Biller remittance type code value invalid, must be 'Sta' or 'Pre' | Update biller remittance type code with 'Sta' or 'Pre' | | BPBMSAPI_ERR_0003 | 400 | State Code value is invalid, must be a valid value from the API YAML | Update state code with a valid 2 character state code listed in the YAML file | | BPBMSAPI_ERR_0004 | 400 | File Format for the specified Concentrator RPPSID is invalid, must be 'MOD-CIE' | Update file format to 'MOD-CIE'.
