# 3-D Secure response codes

Error codes help you debug issues that occur as a result of sending badly formatted requests. The `responseMessage` is a short string that provides a brief explanation. The following tables list the available reason codes, as well as their possible causes.

The following fields are in the body of the response:

- responseStatus: Valid values include: SUCCESS, DENIED, or ERROR. SUCCESS means the request was approved by the issuer or completed successfully. ERROR is only returned for 4XX or 5XX responses.

- responseCode: This field contains a shorter description of the processing result. For 200 responses, this may be displayed to the consumer.

- responseMessage: This field contains a longer, more descriptive message. These messages are not intended to be displayed to the consumer.

- hostMessage: The term "host" refers to the system from which J.P. Morgan has received a response. The hostMessage is mapped to J.P. Morgan’s response fields, but the unaltered message is returned, if received. For 5XX responses, the presence of this field indicates where the error exists.

## Successful responses (200-299)

In general, a `200`** **status code indicates that a request has successfully processed.

> To determine whether a transaction was approved or declined, you will need to review the `responseStatus` field to identify whether or not the issuer has approved the transaction (`SUCCESS` or `DENIED`).

## Client error responses (400-499)

A `4XX`** **status code indicates that an error has occurred during a request, and provides a list of specific codes. Additional fields are provided in the body of the response to help identify the error. Address the problem and resubmit the request.

## Server error responses (500-599)
