In the fast-paced world of web development, hitting that “refresh” button and seeing nothing but a spinning wheel can send shivers down your spine. It often means something’s gone wrong behind the scenes. In our interconnected digital environments, APIs are crucial for seamless user experiences. They let different parts of your app talk to each other and connect with outside services. It's crucial to monitor these interactions, especially with front end monitoring tools that help ensure everything loads as expected. In this blog, we’ll explore how API monitoring can help you achieve your goals, whether you want to improve performance or understand how everything works behind the scenes.
One tool that can help you with API monitoring is Alerty's frontend monitoring solution. It can track and measure the performance of your API calls so you can identify and fix issues before they affect your users.
An API, or Application Programming Interface, is the intermediary that allows two systems to communicate. Imagine it as a translator who helps two languages understand each other.
An API offers the rules and definitions for how these interactions happen. Each API comes with its own documentation and specifications, which guide the transfer of information.
APIs are game-changers. They let you expand capabilities without heavy resource investment. Businesses use APIs in three main ways:
This flexibility allows you to enhance functionality and offer more robust solutions.
APIs can add significant value to your business, benefiting customers and employees. Understanding what an API endpoint is and how to measure performance is crucial for capturing this value.
Monitoring tools can help track performance metrics, ensuring your APIs run smoothly and efficiently.
API monitoring is a watchful guardian over the digital pathways connecting various applications and services. APIs, or application programming interfaces, serve as the essential communication links between apps, allowing them to exchange information seamlessly.
Picture them as the invisible hands ensuring your food order app smoothly interacts with the restaurant system, delivery service, and payment gateway.
But what if an API encounters an issue? This is where API monitoring steps in. These tools track responses by closely observing APIs' performance, availability, and functionality and ensure they meet expected benchmarks.
Alerts are triggered if an API falters or slows down, enabling developers to act swiftly before users notice any disruption.
With 75% of businesses managing an average of 26 APIs per app, with that number set to rise, it becomes clear how vital API monitoring is.
Over half of businesses rely on APIs for all their apps, and over half plan to fully integrate APIs into all applications in the coming years. Ensuring seamless performance is key as companies increasingly depend on these digital connectors.
A poorly performing or broken API can frustrate users, malfunction apps, and cause businesses financial losses. API monitoring helps fix issues early before they escalate, keeping apps and customers happy.
Modern APIs facilitate complex integrations between systems, apps, and microservices. Even the most advanced APIs require rigorous monitoring practices to maintain long-term efficiency.
Fortunately, teams can use various strategies to secure the performance and reliability of enterprise APIs.
Uptime monitoring involves checking an API endpoint regularly to ensure it's accessible and responsive. A system alert is triggered if the API doesn't respond or takes too long. Key metrics include:
Service level agreements (SLAs) often specify required uptime percentages, mandating 99.9 percent or higher.
Performance monitoring assesses how quickly and reliably an API responds to requests. It helps identify:
Metrics like response time, latency, and throughput are typically measured. Performance monitoring can also track error rates, indicating the percentage of requests that lead to errors.
Synthetic monitoring mimics user paths through an app. Scripts simulate user scenarios, device types, and locations to evaluate app performance. This allows teams to identify issues before users experience them proactively.
Real user monitoring (RUM) observes the experiences of actual users, providing detailed data on
This facilitates more fine-grained decision-making by capturing real-world insights into user experiences.
Validation monitoring verifies an API's behavior by sending test scripts to check for correct:
It’s especially useful for identifying issues with multi-step processes or the underlying logic of an API.
APIs are among the likeliest targets for cyberattacks, so security monitoring is crucial. It involves:
Security monitoring often uses encryption and authentication protocols to ensure only authorized users can access API data and to protect against threats like:
Integration monitoring tests interactions between an API and the other apps and systems it communicates with.
This ensures that all parts of a system work together as expected, identifying issues at interfaces between systems. It’s especially useful within microservices architectures.
APIs often transmit sensitive data, increasing the need for compliance monitoring. This ensures adherence to relevant privacy and industry standards, such as:
Teams can track practices like data handling, encryption standards, and access control mechanisms to maintain legal compliance and client trust.
APIs evolve, adding new features and retiring old ones. Versioning monitoring tracks API changes over time to ensure that updates don't negatively impact applications relying on the API.
It might involve comparing functionality between:
Regardless of the approach, teams should prioritize real-time monitoring to receive instant feedback and resolve issues before they disrupt service.
Real-time monitoring often uses dashboards and status pages to provide immediate insights and automate system alerts for managing high-availability or critical workflows.
In today’s tech world, microservices are everywhere. They break down large applications into smaller, manageable parts. While this makes things scalable and efficient, it also adds complexity.
Each microservice communicates through APIs. When one service changes, it can affect others. Monitoring APIs keeps everything running smoothly.
APIs are no longer just internal tools. Many companies now offer them as products to third
parties. This shift means companies must meet strict performance standards. If an API fails, it can damage customer trust and lead to lost revenue. Monitoring helps catch and fix issues quickly.
The API-first model builds APIs before the applications that use them. This avoids poorly designed APIs that can’t handle their tasks. Continuous monitoring ensures APIs remain strong and user-friendly throughout development and production.

API monitoring is your go-to strategy for ensuring that each request to an API stays healthy over time. This is essential for agile teams that push updates several times a day. Monitoring helps catch errors and performance issues as they arise, allowing for quick fixes before customers feel the sting.
By regularly testing and analyzing API endpoints, you can track how they behave across different environments and deployment stages. This ensures everything runs smoothly, reducing the risk of bad code reaching production.
Critical business workflows can become complicated, often involving multiple APIs. A solid API monitoring strategy should allow you to systematically test these complex workflows.
You can then monitor the results at every step. This approach helps ensure that all systems communicate effectively, providing a seamless user experience. By mimicking real-world scenarios, you can better understand how your APIs perform under stress.
A third-party API might be the culprit if you're troubleshooting an issue and can't find the source. Monitoring these external endpoints can save you from chasing problems beyond your control.
With the right setup, you can catch issues before they affect your users. This proactive approach can help you manage dependencies more effectively, improving the overall reliability of your applications.
Security should be a top priority for any API. Monitoring for vulnerabilities is a key part of maintaining a secure environment. By configuring and running security checks in:
You can catch potential threats before they become a problem. This continuous monitoring approach can help you identify and address vulnerabilities early, reducing the risk of data breaches and other security incidents.
API monitoring ensures everything is running smoothly. Are your APIs responding correctly and quickly? Monitoring tools check availability and can alert you if something goes wrong.
When applications depend on each other, a hiccup in one can disrupt others. You can find and fix these issues by tracking availability before they affect users.
APIs might be working, but are they fast enough? Monitoring tools measure response times and flag sluggishness.
They help you optimize performance by analyzing HTTP response codes and checking for consistent performance across different environments. If performance dips, you’ll know right away.
Getting a response from an API isn’t enough; it has to be accurate. Monitoring tools ensure data is correct and formatted properly, which is crucial for multi-step processes. If something’s off, these tools will alert you so you can fix it before it affects users.
Many applications rely on third-party APIs. Monitoring tools give you visibility into the performance of these external services. You’ll know whether to contact your partners or team to resolve the issue if something goes wrong.
APIs can change; when they do, your application might need updates to stay compatible. Monitoring tools alert you to changes in functionality so you can ensure your app continues to work smoothly with external services.
APIs can be a security risk, especially if improperly maintained. Monitoring tools watch for suspicious behavior and notify you of potential breaches. This helps keep your network secure and protects against threats from other connected APIs.
Getting started with API monitoring can feel overwhelming, but it doesn't have to be. Begin by researching software and hardware vendors specializing in API monitoring.
These vendors offer tools to help you effectively manage the APIs your website or application depends on for critical data or processes. Follow your organization’s request for proposal (RFP) process to find the best fit.
Not all APIs are created equal. Some are essential for your operations, while others are less critical. Prioritize monitoring APIs that your website or native application rely on for critical data or processes. Consider APIs you manage that customers, end users, or developers rely on for data or processes.
Once you’ve identified the APIs you want to monitor, it’s time to start testing. Begin by checking the API endpoint's availability.
Testing isn’t just about availability and response time. You also need to validate the data the API is returning.
API monitoring isn’t just about testing individual endpoints. Many APIs are used in multi-step processes, such as authentication or transaction completion. Ensure that these processes work as expected.
API monitoring is a team effort. Work with your developers and other stakeholders to identify which APIs are critical and what tests must be performed. Encourage open communication and collaboration to ensure your API monitoring strategy is effective.
API monitoring is not a set-it-and-forget-it process. It requires ongoing attention and adjustments as your applications and APIs evolve. Stay flexible and be willing to adapt your monitoring strategy as needed.
As part of API monitoring, any good dashboard should include checkups for availability (connectivity), correctness, and performance. Among those, here are the key API metrics you should always measure:
Application-specific metrics give insight into how well your application performs independently of other metrics. These are good metrics for website benchmarks and are worth tracking over longer periods.
Requests per minute (RPM) is a performance metric that measures the number of requests your API will handle per minute. While this can change depending on the day of the week or even the time, RPM is the average number of requests.
Network latency is the time it takes for data or a request to travel from the source to the destination. It is measured in milliseconds.
The closer your latency is to zero, the better. If your latency is high your whole website will suffer and in return, this will negatively impact your user’s experience.
Your APIs will fail, it’s not a matter of if but rather when, so it’s important to note how many times these happen. Knowing if an API, especially an external one, can fail helps you decide on a course of action that can lead you to create certain fallback scenarios or switch the service provider altogether.
Your APIs will depend heavily on how well your infrastructure is set up and performs. Keeping that in mind, there are a few very important API metrics you should watch out for to ensure your APIs are performing as they should.
API uptime lets you check if you can successfully send a request to the API endpoint and get a response with the expected HTTP status code.
This is usually calculated based on the number of minutes or hours the server is available during a selected period.
TTFHW will be obvious to most developers since, more often than not, the first expression you write in a new programming language will output the text hello world.
In this scenario, the Time to first hello world refers to the time the user needs to make his first API transaction since landing on your web page.
It’s essential to measure the impact your APIs have on your servers. The two most crucial API infrastructure metrics to watch out for are CPU and memory usage. High CPU usage can mean the server is overloaded, which can cause severe bottlenecks.
Memory usage helps you understand the amount of resource utilization. Based on these two, you can either decide to downgrade your machine or VM, saving a few bucks, or upgrade to ease the stress you put in and to avoid causing a bottleneck.
Picture this: you’ve got an application or microservice locked up tight, protecting its secret sauce. Sometimes, these systems don’t have an API at all. Other times, the API they do offer barely scratches the surface. You’re left trying to monitor performance with a blindfold on.
This black box scenario can make API monitoring a real headache. Monitoring tools need to pull back the curtains, but they can’t if there’s nothing to grab onto. You’ll need creative solutions, like synthetic monitoring or reverse engineering, to get the required data.
APIs are meant to connect everything, but what happens when the data on either end speaks different languages? Imagine trying to connect two devices that spew data in their unique formats. APIs can hit a wall here.
They can’t do their job until those differences are ironed out. If not addressed, this issue can bog down performance and lead to errors. To get everything on the same page, you'll need middleware or transformation solutions.
API monitoring is meant to help, not hurt. Some monitoring solutions can degrade system performance. They might be too resource-intensive or interfere with the API’s regular operation, slowing everything down and creating more problems than it solves.
When choosing an API monitoring solution, you’ll want one that works quietly in the background without getting in the way. It should be lightweight and efficient so it can monitor things without causing a commotion.
It's easy to focus solely on API endpoints, but remember, problems often originate elsewhere. Your APIs will suffer if your database or network is overwhelmed.
Extend your monitoring to the entire stack. This way, you're not just firefighting—you’re preventing the fires in the first place.
Short-term fixes are great, but what about the bigger picture? Historical monitoring data can reveal long-term trends that guide better decision-making. Spotting patterns in latency or error rates helps you understand the underlying issues before they become crises.
If you’re manually checking on your APIs, you’re already behind. Automate alerts to your communication tools so your team can act when something goes wrong. This proactive approach ensures issues are tackled before they escalate.
Your API monitoring strategy can’t be a set-it-and-forget-it deal. Both business needs and technology evolve constantly. Regularly revisiting and updating your approach ensures it stays relevant and practical, keeping your APIs healthy and your users happy.
