Frequently asked questions
--------------------------

What is status?  
The status field represents the overall status of the requested transaction. For successful transactions, 'status' is the only field returned in the response.  
<br />

<br />

<br />

What is reason?  
The reason field displays the reason for a failed or declined Payments API request. In declined or unsuccessful transactions, the API reply includes an 'errorInformation' object and a 'status' field. The 'errorInformation' object contains a 'reason' field.  
<br />

<br />

<br />

What is service?  
A service is the REST API resource you use to request the transaction. REST services include:

* Payments
* Capture
* Reversal
* Refund
* Credit
* Void

<br />

<br />

<br />

What is an HTTP status code?  
The Payments API responds with the standard HTTP status codes, which include, 201, 400, or 502.  
<br />

<br />

201  
This HTTP status code confirms that the Cybersource API created a transaction resource ID. If you get this HTTP status code for an unsuccessful transaction, Cybersource or the merchant's processor probably marked this transaction as under review, declined, or failed.  
<br />

<br />

<br />

400  
This HTTP status code indicates something is wrong or missing in the merchant's request. Try to correct the request and resubmit it.  
<br />

<br />

<br />

502  
This HTTP status code indicates either a server error or timeout. Retry the transaction, and contact customer support if you need to investigate further.  
<br />
