This feature allows you to club multiple API based functions into a single web API call. This single API can be also referred to as wrapper API. After the wrapper API receives the client request, the clubbed API(s) execute sequentially or parallel to return the response to the client environment. The API orchestration can be achieved in the following ways:
1. Parallel Orchestration
Parallel orchestration is also referred to as enumeration. In the parallel
orchestration, an incoming client request is broken into multiple outgoing sub-
requests. Each sub-request executes through different service end-point
simultaneously and captures a response.
Therefore, the responses of all sub-requests are combined and then returned
to the client.
2. Sequential Orchestration
In the sequential orchestration, you can access multiple end points by
automating a number of sequential calls. After the single API point (wrapper
API) receives the client request, it sequentially invokes multiple service points
to fulfill or authorize the client request.
