What are API management tools?

Application programming interfaces, or APIs, are sets of communication protocols, subroutines, and other tools that help programmers develop and integrate software. APIs can allow web services, applications, libraries, operating systems, and more to perform certain functions through abstraction, especially those concerned with communication and integration with other systems. This allows programmers to add further functionalities when building applications through the use of APIs without the need to understand the full extent of operations going on behind the scenes of a function. For example, developers can pull data from a communication API to integrate text or voice communication functionality in their applications. APIs are often used to successfully build microservices or collections of individual services that make up an application. Developers can arrange loosely connected microservices instead of building monolithic programs to create more efficient and lightweight applications. This creates an application structure by which each microservice needs only to store data if that data is relevant to its exact function. Then, it can pass off that data to another microservice within the application or pull data from another microservice using APIs. Of course, many companies and development teams build APIs for external developers. Upon publishing, these APIs can then be monetized and analyzed to benefit the API provider. API management platforms enable companies to maximize the value of their published APIs. API management software picks up after API design software, which allows users to handle the preproduction and development of APIs on the backend, to enable developers to monitor, control, and monetize their APIs once they are created and published. In the same functional vein as other management solutions, API management platforms allow users to control which of their APIs are accessible, permit edits to APIs when they are needed, assess user analytics, and more. These software tools also provide an API gateway that handles any incoming API calls from users and returns relevant results to those users. In conjunction with API design software, API management solutions go beyond backend control to allow users to maintain full lifecycle API management.

What are the common features of API management platforms?

The following are some core features within API management software that can help users: API editing: API management platforms let developers oversee live APIs, give them editing tools when small changes need to be made, and provide the ability to delete any no longer needed APIs. This gives teams complete lifecycle API management and helps keep company strategies in sync by ensuring that current focuses are reflected by relevant APIs, uncluttered by redundancies or outdated interfaces. In many cases, user feedback and usage analytics are crucial for getting an API to the best possible state, meaning post-publishing editing capabilities are vital. API monitoring: API management tools constantly monitor a provider’s APIs, tracking metrics such as performance, functionality, user accessibility, traffic, and signs of security threats. For example, the software will monitor an API’s response time when called to perform a function, comparing it against benchmarks set by the API provider. The software monitors this response time as a constant average over time based on the many calls that can occur. Often, correlations between performance slips and possible causes, such as increased traffic, can be monitored to provide teams with the most relevant information regarding their APIs’ status. Data transformation: Many API management platforms include functionality for translating complex datasets and backend systems into formats that applications can interpret. This ensures that clients’ API calls can be completed successfully and that the data they seek is returned to them in a useful state. With API management platforms handling this translation, the burden is shifted off developers’ shoulders when building each API. Developers don’t have to include scripting to handle this data translation, as they can get their APIs up and running more efficiently. Documentation: API management solutions allow teams to create documentation around their APIs, including action items, issue logs, etc. These software tools’ documentation functions work with monitoring tools to ensure that everyone understands what’s going on with their APIs. For example, if a published API dips below performance benchmarks, relevant team members will see that reflected in documentation and can take steps to remediate the issue. This keeps development teams informed and allows for quick turnarounds when potentially costly problems arise. Reporting and analytics: API management tools offer reporting and analytics around each API’s usage. This helps developers see how their APIs are being used and with what frequency. API management software grants companies finer control over the value and data streams their published APIs generate. User analytics such as API traffic provide essential data that can help inform future product decisions, for example, and API management solutions give companies a toolset to perform comprehensive analysis. Via dashboards and custom metrics, development teams can keep tabs on API usage and even explore the demographic trends behind API calls. Automation: API management platforms automate many processes and tasks necessary for effective and efficient API management. Monitoring, for example, occurs constantly and automatically to provide teams with real-time updates whenever an issue arises or other relevant information becomes available. Sometimes, teams can even set custom alert events based on certain API activities. API management tools can also automatically produce actionable documentation around API activity, such as traffic trends and errors, giving developers a starting point to act on new information or remediate problems. The automated functionality of API management software gives development teams peace of mind while freeing them to focus on other tasks. Traffic control: Many API management products go beyond traffic monitoring to grant teams full traffic control. This gives companies the tools necessary to keep their APIs more secure. For example, API management platforms can monitor for abnormal traffic spikes and then limit access to prevent overloads like DDoS attacks. This software also allows administrators to control API access to keep out suspicious visitors—this level of control grants API providers security and proactive tools to maintain smooth operations.

What are the benefits of API management software?

Convenience: API management tools save users time and effort by simplifying and automating processes like monitoring, analytics, documentation, and more. These solutions bring a development team’s published APIs under one dashboard, allowing them to drill down, manage, and edit APIs as needed. Automation frees development teams to focus on other tasks without being bogged down in near-constant upkeep, relying instead on the monitoring and alerting capabilities provided by the software. Transparency: These solutions allow users to monitor every aspect of their APIs. Between reports and analytics, documentation, and tagging, team members are aware of exactly what’s happening with their APIs at all times. Via dashboards, development teams gain a holistic view of the statuses, traffic, trends, and issues related to their APIs. Teams can then collaborate on action items using clear, consistent documentation tools. Comprehensive management: The automation, monitoring, and documentation functionalities employed by API management platforms add up to a comprehensive management strategy that can be quite difficult to replicate without this software. API managers help by constantly parsing API data to present teams with relevant information and mitigate opportunities for human error. Value addition: API management tools help companies that publish APIs to get the most value out of them. Enterprise-grade monetization tools lay the foundation for such value, allowing businesses to profit effectively when clients call their APIs. Actionable API usage metrics such as traffic trends, issue reporting, and more give teams crucial data, which can then be leveraged to inform product development and improvement. Some API management tools also include features that can help attract developers, like intuitive developer portals.
