API Documentation

In-depth reference documentation for iQmetrix API's.

NAV

OVERVIEW

When an invoice containing Tio products is tendered, a payment objected is created for each Tio product with a unique paymentReferenceID to identify it.

To complete payment to Tio and also notify AMDOCS of the payment (if applicable), two child request objects are created and inserted onto the RQ queue service for asynchronous processing. When a request is processed, API calls are made out to Tio/AMDOCS which include paymentReferenceID of the parent payment.

If a request completes successfully, results are written back to the payment object and the request is permanently cleared from the queue. If a request fails it will be moved into a ‘retry’ or ‘doNotRetry’ state based on the nature of the failure

Throughout the life of a request, all attribute changes are logged to ensure a complete audit history can be traced. Each change to a request, by process or by API user, will trigger the creation of a new audit object.

Integration Queue

API Functionality

The integration queue manager is a simple API allowing consumers to do the following:

NOTE: The Integration Queue Manager API is not intended to be used for reporting or mass data collection purposes

Authentication

Standard iQmetrix Authentication API Details apply, see Obtaining an Access Token.

In order to access the authentication API consumers will require the following parameters which will be privately generated and provided.

Name Description
username username provided to iQmetrix, usually an email address
password The password, provided when an account is created
client_id The client ID provided by iQmetrix
client_secret The client secret

Headers

Consumers shall access the Authentication API to retrieve a valid Access Token which will then be included in the header of all subsequent Integration Queue Manager API queries.

Authorization: Bearer (Access Token)
Accept: application/json

ENDPOINTS

There are two different environments that are accessible: Production and Release (RC).

The production environment can be reached at: https://integrationqueuemanager.iqmetrix.net

The release environment can be reached at: https://integrationqueuemanagerrc.iqmetrix.net

These endpoints will reach a load balancer which will redirect you to one of our available datacenter endpoints, depending on load/availability. If your application encounters an issue with this redirect, you can try the following static endpoints:

Payments

When an invoice containing Tio products is tendered, a payment objected is created for each Tio product it contains.

A unique paymentReferenceID is generated within RQ to identify each payment object. If the customer pays using a combination of cash and credit, a separate payment object is created for the cash and credit portions.

The paymentReferenceID is currently only guaranteed to be unique per database, although future projects will require it to be globally unique. It is intended to be a unique payment identifier across all vendors.

Request

A request object is created as a child of a payment and represents either a Tio or AMDOCS API request that has been placed onto the RQ queue service for processing. A request may be in any State. If a request is processed and a successful API response is returned, the response data is written back to the parent payment and the request is permanently deleted.

Request objects can be mapped to their parent payment using the paymentReferenceID attribute.

Audit

The modification of any request attribute (by process or by API user) will automatically trigger the creation of a new audit object.

An audit object is a complete snapshot of a modified request including all the request’s attributes with a few additional tracking attibutes. Audits are made available strictly for the purpose of fallout reconciliation.

If a particular request is left in a ‘doNotRetry’ state, it is often beneficial for operations to review it’s audit history in order to reconcile the payment.

REQUESTS

GET the Root

This resource does not have any attributes.

Instead it offers the initial API accordances in the form of the links in the JSON body.

It is recommend to follow the “url” link values or Location headers where applicable to retrieve resources instead of constructing your own URLs, to keep your client decoupled from implementation details.

Requests

Toggle a Request Between ‘Retry’ and ‘DoNotRetry’ States

This action allows you toggle a request between ‘Retry’ and ‘DoNotRetry’ states.

If successful, the resulting state of the request is returned and the time of next retry will be set to the current UTC time.

The state and RequestId you wish toggle into must be included in the query body.

Request

PUT /companyID/{CompanyId}/database/{DatabaseId}/requests/{RequestId}/retry/{Retry}

DELETE a Request Permanently

This action allows you to permanently delete a request in a ‘doNotRetry’ state from the queue.

The call should be used with caution only after complete reconciliation of the underlying payment.

Audit info for the deleted request will be held for the standard 7 day window after deletion.
