As discussed in our previous post on API Management Fundamentals, the success of an API initiative is dependent on much more than developing great APIs. One of the most important components of a successful API program is diligent monitoring and measurement.
Performance metrics—such as the number of downloads, uptime, and amount of use—help gauge the success of your API with hard numbers. They can alert you to problems from the outset. For example, you may notice a steep drop in data flow that can indicate a bug in the API.
The metrics may also help pinpoint misuse of the API, such as excessive requests for certain data. Ideally, you will provide unique API tokens for users, which will identify who is making calls to your API. An API Management platform can provide these insights and capabilities.
While this is all very important information, the primary focus of these metrics is on trends and usage patterns. These metrics don’t help to determine precisely how to improve APIs for users, fix the problems they may be encountering, or identify the functionality they would like to see. Without a means to capture this feedback from users, the success of the API program may be hindered, and companies miss out on tremendous opportunities.
