CamundaCon 22

  • Title: 10 Things You Can Do with Camunda Cloud Without a Line of Code
  • Description: I’m a fullstack developer – I love writing code to solve problems. I’m also a serverless fan and use SaaS products everywhere I don’t need production depth. What’s the link to Camunda Platform 8? Simple: with Cloud Connectors, you don’t need a line of code to interact with HTTP APIs. If you simply want to interact with an existing service, you don’t need a separate application. In this session, I’ll show you how it works with ten examples: I’ll integrate with Trello, Github, Hubspot, and more.
