SS23 – vvvv – Working with REST APIs

Recording of the session on June 29th 2023 / In English Language

We will discover what REST APIs are, and wrap one as vvvv nodes to use it in our projects. We’ll use the VL.SimpleHTTP 1 library. We’ll also see how to read the documentation of a REST API, and test it in external tools such as Postman.

What you will learn:

  • HTTP basics
  • What a REST API is
  • How read an API documentation
  • How to test an API outside of vvvv
  • How to communicate with this API in vvvv
  • How to build a nodeset to re-use later

Who is it for?

Everybody who ever came accross a REST API that does something cool but did not know how to use it.

Presumed knowledge

  • Understanding of VL’s concepts (records, operations), knowing what a URL is.
  • Windows Computer
  • A 3 button mouse
  • We recommend you to use an external monitor connected to your laptop or PC, this would help you to follow the instructors screen while you patch along on your own device.
  • The instructor might ask you to share your screen, therefore it is recommended to remove personal data from your desktop.
