In the world of application development, Application Programming Interfaces (APIs) enables the communication and exchange of data between software. Testing your API is essential to the proper integration and delivery of quality software and product. Unlike UI testing, API automation testing is designed to withstand the short release cycles and frequent changes that occur while using best practices for software development and IT operations. API testing is more important than ever.

Mocking APIs is an increasingly popular trend, with more and more developers seeing the advantages of mocking dependencies rather than spinning up actual duplicates of resources. On a high-level, a mock API means that you have a service that returns static data, which in turn is based on a real API.

Offering customers a variety of ways to pay for your product allows for flexibility and ease. In general, there are two ways for customers to pay for usage: Post-paid and pre-paid. Pre-paid is sometimes also referred to as PAYG, or Pay-As-You-Go. Post-paid usage can sometimes lead customers to have billing surprises if they are not tracking their usage closely. This can cause headaches for these users and can also cause issues for the service provider.

Many API developers and companies struggle to find ways to easily set up systems to monetize their APIs. Some are simple but not customizable, some are complex and require massive engineering effort to actually get it all running. To make things easier, Moesif created a feature a few months ago called Billing Meters which gives massive customizability but with a minimal amount of code and engineering effort.
