The Openpath NMI Emulation API can receive Transactions posted in any of the following formats listed below:
|A query string is a part of a uniform resource locator (URL) that assigns values to specified parameters. A query string commonly includes fields added to a base URL by a Web browser or other client application, for example as part of an HTML, choosing the appearance of a page, or jumping to positions in multimedia content.|
|Form Data||The FormData interface provides a way to easily construct a set of key/value pairs representing form fields and their values, which can then be easily sent using the XMLHttpRequest.send() method. It uses the same format a form would use if the encoding type were set to "multipart/form-data".|
|X-WWW Form URL Encoded (Recommended)||
"application/x-www-form-urlencoded" is the default encoding (in HTTP terms Content-Type) a web form uses to transfer data, not multipart/form-data. To send an HTTP post request on form submission with a Content Type of multipart/form-data, one must explicitly specify this as the enctype value.
Transaction sales are submitted and immediately flagged for settlement.
Transaction authorizations are authorized immediately but are not flagged for settlement. These transactions must be flagged for settlement using the capture transaction type.
Transaction credits apply an amount to the cardholder's card that was not originally processed through the Gateway. In most situations credits are disabled as transaction refunds should be used instead.
This action is used for doing an "Account Verification" on the cardholder's credit card without actually doing an authorization.
