As we have seen throughout this book, we can build integration workflows powered by Logic Apps, Microsoft Flow, or Power Apps without having any hand in the code. In this section, we will discuss how we can leverage existing APIs and make standard custom connectors to connect integration platforms and services, whether they are cloud resources or on-premises applications.
