Using the Weekly API Science Report to Improve Customer Experience

Your API Science account automatically provides you with the “Weekly API Science Report” which is delivered by email to the email address associated with your account. Here’s an sample email for an account that runs two API Science monitors: The report proceeds from a performance overview for all of your monitors down to the details […]

Validating API Responses and Performance Using JavaScript

Determining the present state of an API that’s critical to your product’s performance is the reason why companies apply API monitoring on a 24/7 basis. If your product depends on a sequence of calls to multiple APIs (perhaps internal as well as external), your product could appear “down” to your customers if even one of […]

Timing-Out Slow-Performing External API Requests

API performance varies depending on many variables, including the response of the Internet (for example, resolve time and transfer time) and the timing for work that occurs on the remote server (connect time and processing time). My last post illustrated that calls to the World Bank Countries API sometimes exhibit abnormally slow performance. Unpredictable, though […]

How One Slow External API Can Bring Your Product Down

APIs receive a request from a user, gather data and/or perform some processing based on the request, then return the requested information (or other result) to the user. This sounds simple. But a lot can go wrong, and even when everything succeeds, the time it takes to complete the process can be highly variable. Greater […]

API Performance as a Function of Call Location

Some weeks ago, I created API monitors that call the World Bank’s Countries API from four different locations: Ireland, Oregon (U.S. West Coast), Tokyo, and Washington, D.C. (U.S. East Coast). All four monitors request the World Bank information for Brazil. Here’s a recent view of my API Science Dashboard for these monitors: Each monitor is […]

Evaluating the Performance of Critical APIs Using API Science’s Data Analysis Tools

The API Science API monitoring platform provides an array of data analysis tools for viewing the performance of internal or external APIs that are critical to your product, from the top level (represented by our weekly summary report) down to the fine-grain details of the results from a single test run of an individual monitor. […]

API Performance Outliers Based on Location

Monitoring API performance from various locations around the world is critical in order for you to know what your global customers are experiencing. The “Weekly API Science Report” that you receive with your API Science membership provides a good summary of the status of the APIs you are monitoring. A week ago, for my post […]

Why Location Matters in API Performance Testing

In his 2014 book Flash Boys, Michael Lewis talks about a massively expensive project that burrowed through mountains, tunneled under riverbeds, dug trenches beside country roads, with the objective of creating “maybe the most insistently straight path ever dug into the earth” between Chicago and New Jersey. Why? So that “a one-and-a-half-inch-wide hard black plastic […]
