Let's breakdown the Fax_SendFax call and it's parameters. You can find our API documentation at our Postman collection which you can import into Postman and prototype quickly. Fields may be optional or required. Some fields have iterating values (Files0...999) where you can have multiple values. You can test your implementation using Postman to prototype your code. We love Postman but we don't recommend you utilize their code samples as we have seen issues with some platforms.
We expect you have some level of knowledge of API development with Restful APIs.
If you don't we suggest these great courses on udemy.com.
