REpresential State Transfer (REST) was developed in parallel to HTTP and describes an approach to how distributed systems can communicate with each other. REST itself is not standardized, but often uses standardized protocols such as HTML, JSON or XML. With the development of software-defined solutions in the entire network area (SDN, SDDC, SD-WAN), REST has become the standard method for accessing the northbound API of many network components and is often used for scripting or automation in the infrastructure. To gain an understanding of how to access the API, you can use Postman, a program that allows you to create and test API requests in a graphical interface. The requests can be combined and put together very flexibly. Extensive configurations can also be implemented with just a few clicks using Postman Collections.

-
Target Group
-
This course is aimed at administrators who are increasingly confronted with the fact that access to the components to be managed is shifting from classic methods such as SSH or HTTPS to the use of a REST API. With Postman, you can get to know how the API works and use it quickly.
-
Knowledge Prerequisites
-
The course provides basic knowledge of the freely usable Postman tools; no special prior knowledge is required. Working with Postman is deepened using some available example components (mainly Cisco APIC). This is done by way of example, so that no special knowledge is required here either. However, an understanding of the API you are using is very helpful for transferring what you have learned.

Classroom training
- Do you prefer the classic training method? A course in one of our Training Centers, with a competent trainer and the direct exchange between all course participants? Then you should book one of our classroom training dates!
-
Hybrid training
- Hybrid training means that online participants can additionally attend a classroom course. The dynamics of a real seminar are maintained, and the online participants are able to benefit from that. Online participants of a hybrid course use a collaboration platform, such as WebEx Training Center or Saba Meeting. To do this, a PC with browser and Internet access is required, as well as a headset and ideally a Web cam. In the seminar room, we use specially developed and customized audio- and video-technologies. This makes sure that the communication between all persons involved works in a convenient and fault-free way.

Online training
- You wish to attend a course in online mode? We offer you online course dates for this course topic. To attend these seminars, you need to have a PC with Internet access (minimum data rate 1Mbps), a headset when working via VoIP and optionally a camera. For further information and technical recommendations, please refer to.
