API Led Connectivity

Use APIs to Integrate

API-led connectivity enables the reusability of the integration flows within

multiple parties. Also, the integration flows can be reused inside the

integration platform. Due to the reusability factor, it helps the developers to

build their logic rapidly and efficiently, thus reducing the overall turnaround

time (TAT). It makes the development process almost 3 times faster and

reduces the integration cost by almost 70%.  

 

In the API led architecture, the IT infrastructure has three distinct API layers:

 

System Layer: In the System layer, various system APIs reside (e.g. for ERP,

CRM, SAAS Applications, etc.). Using the system APIs, these systems can

be accessed. The data residing in these systems gets exposed by these

System APIs in a secured manner.

 

Process Layer: The next layer is process layer where the orchestration

activities of various data such as aggregation, join, splitting, etc. are done

by calling multiple System APIs. For example, an Order Fulfilment Process

API can call systems APIs of the ERP, CRM, Order Management System,

etc. Thus, if any business user or developer wants to Use the order

management functionality or related data, he or she can directly use the

Order Fulfilment Process API, rather than building everything from scratch

using the individual System APIs. 

 

Experience Layer: These are the top-most layer which should be exposed

publicly for consumption. Experience APIs are the means by which data

can be reconfigured easily to meet the needs of multiple audiences. In

addition, the unnecessary methods can be removed and only the

necessary methods can be exposed in Experience APIs in a simple way.
