There are two possible approaches to architecting an insurance aggregator website. The first approach (web service model) connects the aggregator website to the insurer’s system by a series of API calls. The second approach (all-in-one model) handles everything under one website.
In both models, once you have defined the insurance product(s) you wish to offer (e.g. Private Car / Van, Home / Contents, etc.), you then need to negotiate and agree with the insurers / intermediaries that they are willing to offer their online products via your aggregator service.
The insurers will be looking for you to invest substantial sums to market your service.
There are two stages to the quote retrieval. Firstly, some basic rules are supplied to the aggregator. For example, for a motor policy, only drivers aged over 21 may be acceptable.
Then, secondly, if these rules are passed, the aggregator will make a call over the internet to the insurer’s system (via a web service API) that will supply the policy information entered on the aggregator’s site. Then, the response from the web service will return the premium amount and a web address link to a landing page on the insurer's site for the client to click on to proceed with the quote. It will be important that this call is returned within 1 – 3 seconds.
The quote is accepted, payment taken, and documents generated by the insurer’s website.
In this model, the customer never leaves the aggregator website. All policy information is still captured on the aggregator website and the premium calculations are performed within the aggregator website. The customer selects the provider they would like. Then payment is taken and documents are generated by the aggregator site.
The policy information can be exported via a batch transfer to the insurers' backend systems.
