I cannot find any documentation on classes, properties and methods? Do you have any shared documentation that describes the classes, methods and properties? I want to read what they do and see examples on how to use them?
Do you know of any “ready-to-go” solutions and/or shared projects using this API?
Hello. Unfortunately we don’t have any API documentation. What we typically do is provide guidance on how to do what you’re wanting to do, as well as code snippets. To get started you’ll want to download and try out this Sample C# Project as well as learn about how we do Data Validataion and Broken Rules. There’s also a lot of code requested so far, such as how to sync with accounting software, here: Sample Code to Synchronize Invoices with Accounting Software and plenty of code snippets on this site if you also want to try a search.
