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 captures flag existing authorizations for settlement. Only authorizations can be captured. Captures can be submitted for an amount equal to or less than the original authorization.
