Continuous insight into your
API performance

Proactive, API Monitoring ensures APIs & web services are fast, functional, and reliable.

The Value of API Monitoring

APIs power modern digital experiences

APIs are the connective tissue underpinning the modern age of digital transformation. From the rise of microservices, the spread of single page web applications (SPAs), to the dominance of native mobile apps, organizations rely on APIs to power their businesses. When an API fails, it disrupts the performance and user experience of your websites and apps, putting your business reputation (and potentially revenue) at risk.  Proactive, continuous monitoring of the API services to ensure availability, functionality and reliability of your critical business processes has never been more critical than it is today.

Better API Insights

Gain clear visibility into the performance and functionality of first- and third-party API services, API management providers, microservices, multi-step flows, and single-page applications (SPAs).

Pinpoint & Resolve API Failures Quickly

Continuously monitor all your first- and third-party APIs to verify the availability, response time, and data quality for these transactions. Proactively monitor single endpoints or critical application flows across multiple APIs.

Reduce Root Cause Analysis and MTTR

Easily identify the root cause of failure in service-oriented environments so you can spend your time fixing issues rather than hunting for them.

Minimize the Business Impact of API Failures

Gaps in API performance don’t only impact UX of your web apps, but also disrupt workflow efficiencies, hurt brand reputation, and can lead to significant revenue loss. Find, fix and prevent API issues earlier to drive better business outcomes.

API Monitoring
Frequently Asked Questions

What is the difference between the free tool APITester.com and Rigors full API monitoring solution?

Rigor APITester.com is a free tool from Rigor designed to be used for single point in time available check and manual purposes.

Data is not collected or trended over time, but rather shows you only the current availability of the API or flow at the time of the test. Useful to spot check, but does not provide the assurance of a monitoring and alerting solution.

Rigor’s full solution is an enterprise-grade solution collects data, tracks, trends and provides an always-on solution for understanding API performance over time, across complex systems.

Why monitor API flows?

Monitoring a single API endpoint is a good place to start. However, most appliances don’t just use a single API. They use a flow of APIs: data from API 1 is sent to API 2, data from API 2 is used to compute new information, which is then passed on to API 3. Knowing that the individual API endpoints are available, fast, and functional doesn’t give you the whole picture. Only by testing the entire flow can you ensure the API is working.

What are the most important metrics to measure API performance?

The most successful companies monitor and alert on multiple metrics for APIs, since each reveals a different aspect of performance or where a problem could be:

1. Availability: Tells you if the API is available from different locations
2. Connection time: Slow connection time can indicate the API endpoint is overloaded or has too many simultaneous users.
3. Response time: Slow response times indicate backend problems with the application or data sources
4. Status Code and Response Data: Getting a response back quickly doesn’t matter if its an error, or doesn’t contain the data that you are expecting. You should make assertions about the response to validate the API is functioning.

Why monitor APIs?

APIs are the heroes of the modern web. 

The rise of microservices, single-page web apps, and the continued dominance of native mobile apps have made API a mission-critical component of most organizations.

APIs drive modern applications and infrastructure, so it’s critical to understand how APIs are impacting our businesses.

When an API fails it disrupts the performance and user experience of your site, putting your business reputation (and potentially revenue) at risk.
