Agnos APIs are made of a set of abstraction levels provided to integrators to develop their applications should it be a payment application, a transit application, a cash withdrawal application, a vending machine application, a test application, … This level of applications is called L3.
...
We list different levels of abstraction to integrate with Amadis' L2:
Rich API: this is a legacy API provided a low granularity
OLA: this is a normnalized API provided for payment applications that fit into NexoFast’s model
Callbacks: this is a normalized API provided to better control the card processing flow
Exit conditions: this is a normalized API provided to better control the card processing flow without the drawbacks of using calllbacks
