The SoundCloud Java library created by Darius Morawiec aims to simplify the access to the API capabilities of sounds, users, and sets. Resources include dependencies, usage with API, REST, GET, PUT, POST, and DELETE, examples, and processing. The author suggests that the service of Apigee is optimum to learn and test the official SoundCloud API.
At first, the phrase "my API is my Product" seems misleading. An API is a way to deliver a product, rather than the product itself, right? The term designates a "set of programming instructions designed to access an app." Period. We're talking about a means, rather than an end. That's why there are so many different products relying on APIs: Twilio for phone, Mailjet for email, Google Maps for maps, etc.
This tutorial from the FINRA Technology website explains how even novice developers can create a basic REST service for evaluating whether a number is a prime or not. The service is built using automated computing service AWS Lambda, as well as AWS API Gateway and IAM for authentication.
Pactas, recurring billing solution provider, offers the Pactas API that allows developers to include Pactas functionality within third party apps and websites. Any need for recurring billing (e.g. carsharing, music flatrates, cloud services, etc.) can be simplified and streamlined with the Pactas solution. Pactas enables users to manage subscriptions, track payments, and map pricing. Access to the platform can customize to each users' situation depending on need, resources, and integration opportunities.
