This chapter describes the Oracle Communications Services Gatekeeper OneAPI Payment/Diameter communication service in detail.
Applications use the RESTful Payment interface to charge an amount to an end-user's account using Diameter and to refund amounts to that account. Applications can also reserve amounts, reserve additional amounts, charge against the reservation or release the reservation.
The Services Gatekeeper OneAPI Payment interface complies with Open Mobile Alliance (OMA) specifications. See "OneAPI Payment Interface" in Services Gatekeeper Statement of Compliance for a reference to the supported specification and RESTful bindings schema. Note that this interface does not support volume charging.
See "Using the OneAPI RESTful Interfaces" in Services Gatekeeper Application Developer's Guide for general information on creating applications using the OneAPI RESTful interface.
The information provided in this document is based on the OneAPI specification and provided here for convenience.
When the Administration Server for your Services Gatekeeper domain is in the running state, the REST service descriptions of these operations can be found at
http://host:port/oneapi/1/payment/application.wadl
Where host and port are the host name and port of the machine on which the Services Gatekeeper Access Tier (AT) services are running.
The Charge Amount operation charges an amount directly to an end-user's application using the Diameter protocol.
To charge an amount for a call, provide the telephone address of the end-user (endUserId), a reference code (code) in case there is any dispute regarding the charges, and the billing information to charge for the call.
http://host:port/oneapi/1/payment/endUserId/transactions/amount
Where:
host and port are the host name and port of the machine on which the Services Gatekeeper Access Tier (AT) services are running.
endUserId is the address of the subscriber to charge (MSISDN).
The MIME-type for the Content-Type header field can be either application/x-www-form-urlencoded or application/json.
The request body for the Charge Amount operation accepts the following parameters:
endUserId: String. The URL-escaped end user ID. For example, a MSISDN including the ’tel:' protocol identifier and the country code preceded by ’+'.For example, tel:+15415550100.
transactionOperationStatus: Enumeration. This indicates the desired resource state, in this case ’charged'. See "Resource States" for more information.
description: String. The human-readable text to appear on the bill provided so the subscriber can easily see what was purchased.
currency: String. The 3-figure currency code defined in ISO4217.
amount: Decimal. The amount to be charged.
code: String. The charging code, from an existing contractual description that references an operator price point.
clientCorrelator: String. Optional. This uniquely identifies the create charge request. If there is a communication failure during the charge request, using the same client correlator when retrying the request allows the operator to avoid applying the same charge twice.
onBehalfOf: String. Optional. Allows aggregators or partners to specify the actual payee.
purchaseCategoryCode: String. Optional. An indication of the content type. Values meaningful to the billing system would be published by a OneAPI implementation.
channel: String. Optional. Can be Wap, Web, MMS, or SMS, depending on the source of user interaction.
taxAmount: Decimal. Optional. Indicates a tax amount already charged by the merchant or application.
serviceID: String. Optional. The ID of the partner or merchant service.
productID: String. Optional. Combines with the serviceID to uniquely identify the product being purchased.
The Location header field contains the URI:
http://host:port/oneapi/1/payment/endUserId/transactions/amount/transactionID
Where transactionID is the string identifier returned in the response body.
The Status-Line header field returned indicates if the charge has been created or accepted. An accepted response indicates that additional processing is required before the transaction is complete. If the request fails, the Status-Line header field will contain the status code and the reason for the failure. See "Errors and Exceptions" in Services Gatekeeper Application Developer's Guide for more information.
The response body contains a confirmation amountTransaction JSON data structure consisting of the parameters supplied in the payment request.
{"amountTransaction": { "clientCorrelator": "String", "endUserId": "String", "paymentAmount": { "chargingInformation": { "amount": "Decimal", "currency": "String", "description": " String" }, "totalAmountCharged": "Decimal" }, "code": "String", "resourceURL": "URL" "transactionOperationStatus": "String" }}

A resourceURL is included as a reference to the response. The transactionOperationStatus provides the resource state. See "Resource States" for more information.
The Reserve Amount operation is used to update an existing reservation to request additional funds or resources. See "Charge Amount" for more information. Change the following parameters in the request for additional funds:
transactionOperationStatus=reserved: Indicates that we are not changing the resource state, just the value being reserved. See "Resource States" for more information.
amount: The additional reserved amount for this request (not the total amount reserved so far).
referenceSequence: Each time you reserve an additional amount against an existing reservation, make sure to iterate the referenceSequence each time. This ensures Services Gatekeeper can distinguish between new requests for additional amounts, and those that are being repeated due to a communication failure.

Once the resource reservation has been released the amountReserved parameter should have a value of zero. The totalAmountCharged parameter contains the final amount to charge against the reservation.
A resourceURL is included as a reference to the response. The transactionOperationStatus provides the resource state. See "Resource States" for more information.

The client application passes the transactionOperationStatus in the request body so that the resource can be placed into a desired state. Services Gatekeeper either confirms this desired state in the transactionStatus response field, or instead shows a failure state as shown in Table 14-1 and Table 14-2.
