The full lifecycle API management is the lifespan of an API that starts with planning and ends when an API is retired. The life cycle of an API helps in providing your platform digital strategy, run an effective API program and build platforms. Creating a well-executed API can be crucial for digital transformation and it helps to provide a profitable outcome for your organization. You can start with ideation and end with monetizing that idea. Hence, it is critical that you should have a well-defined plan that will make the process seamless and help you to identify potential roadblocks. In our previous blog about Mulesoft Integration, we spoke about business integration and why do you need MuleSoft. In this blog, we will understand the lifecycle of an API.
There are the 5 key stages for the API lifecycle for our API integration services, which helps you with hyperautomation. This term was discovered by Gartner and it means "the application of advanced technologies like RPA, Artificial Intelligence, machine learning and Process Mining to augment workers and automate processes in ways that are significantly more impactful that traditional automation capabilities."
The purpose of API is determined and the user interaction is taken into account. In this phase, it is also important to discuss security, authentication and roles. Besides this, other important aspects may include volume and execution strategy. You can have your business team members identify the services and capabilities an API should explore. Additionally, documenting specific business needs and refining the initial API goals which turns them into a comprehensive set of functional and nonfunctional requirements.
The API manager i.e. a persona which can be represented by people with designations. This can include API product manager or API architect. These team-members prepare a holistic plan to expose your enterprise’s digital assets using APIs. You can start with ideation, including identifying the list of APIs, design (parameters and types), visibility scope, and more. Therefore, the API manager also ensures that the documentation of the API is comprehensive. It is crucial to note that an API documentation is one of the tasks that should be done with utmost clarity or else it can potentially derail the further processes. Currently most of the matured API development platforms support API documentation based on YAML or Open API Specification.
Just like any other program, the APIs also begin with the planning stage. You can define your goals that you are wishing to achieve with this API. You should also look to specify the markets/industries you need to address, taking in account the resources you have. As for the time frame, set it accordingly on the basis of your goals. This is a critical step to insure that you are directing your efforts in the right place.
The API planning includes mapping various resources and operations. Be mindful of the business case scenarios before the API is fully implemented. With many dependent digital strategies relying on APIs, the implementation requires a solid design, which leads us to the next phase of the API life cycle, Design and Development.
Design and Development
The second step, the design and development phase will ensure that your organization uses a contract-first approach. This phase entails recording feedback early, deconstructing the dependencies between projects, and minimizing risks. A contract-first approach is also known for reducing the go-to-time to market. In this phase, you design the contract of your API and share it with your potential clients. The results of this phase is an API contract that details the messages that can be exchanged within your APIs. The actual API can be developed using either an integration framework or using the development language of your choice. The use of an integration framework should be a key part of your APIs’ lifecycle to promote reuse and other value additions. It also helps you to modernize and reinvent the existing parts of your information system. Your usual agile development practices can be applied here.
The APIs can be written in multiple programming languages like PHP, Python, Ruby, .NET, C#, Java and Perl. The second step, the design and development phase will ensure that your organization uses a contract-first approach. This phase entails recording feedback early, deconstructing the dependencies between projects, and minimizing risks.
API development can be accomplished with a single developer, but it is often handled by a separate, dedicated API development team. A team approach allows the developers to access, build, and maintain the company's API portfolio in a controlled environment. Additionally, with many developers onboard, it becomes easier to create the documentation, test cases and even some of the marketing materials that would be required to make public APIs successful for your enterprise. Since this will be a team effort, you will need multiple developers to cooperatively access and maintain their APIs. The entire API team should be responsible to interact with API code, documentation and test files.
After the design phase, deployment of the APIs is the next step. The information regarding the API, such as documentation, tags and external documents, is then transferred to the API catalog. The policies for mediation, traffic management and security should also be defined. Subsequently, the time and visibility of the API is controlled by the line of business. Additional meta information is outlined from the API and reports are generated regarding API monetization and business value.
In the Deployment phase, you have to ensure that you have a continuous integration/continuous deployment (CI or CD) pipeline that automates the delivery of your APIs to the production environment. The CI or CD pipeline reuses the tests that you defined earlier to ensure the APIs to be deployed do not violate your specifications. Those integration tests are automated as part of the pipeline. The automated integration tests should be suited for backward compatibility of your APIs.
In conclusion, APIs, must satisfy a use case for any end consumer, be it your own internal developer team, a client, or the public. Deployment of the API to a secure environment for facilitating easy discovery and consumption is essential for the success of your API strategy line transactions through SAP integration.
After deployment comes testing. The developers should thoroughly test each iteration of the APIs for functionality, performance & user acceptance. Testers can try to loop unsatisfactory results back to developers to further build and refining of the API code. There are different types of testing:
It validates that every feature or function operates as it was intended.
It evaluates how the API performs under load as many APIs are subject to erratic traffic and unpredictable load conditions.
It tracks the API's use and gauges whether it achieves its intended business purpose or not. It can also reveal if any new requirements that can possibly arise from a change in the business process or the API itself.
APIs should get the same amount of attention as your other apps. This means that the APIs should be thoroughly tested and monitored for performance issues and more. Every API should be tested to ensure that it delivers what is expected of it.
After you have successfully released your first version, you are expected to prepare the next version and the one after that. This requires you to get regular feedback to know what to improve next and which areas you should focus on. This is called the monitor phase.
In order to get accurate data in your feedback loop, you will have to monitor various aspects of your APIs regularly. This ranges from developer engagement to API health, usage, and more. Monitoring is a huge part of this retirement process and as important as the previous phases, especially when it comes to tracing the age and history of an API.
As mentioned above, this entire lifecycle management can help you with hyperautomation. This is not just referring to the implementation of tools to manage multiple tasks at a time but also a collaboration between humans. Since the user is the sole decision maker and can use technology to either apply data or use logic.
Future Trends in API Life Cycle Management
API Life Cycle Management is a dynamic field that continually evolves to meet the changing needs of modern applications and businesses. As technology advances, several trends are shaping the future of API management. Staying abreast of these trends can help organizations adapt and thrive in an increasingly connected digital landscape. Here are some key trends to watch for:
1. APIs as Products
In the future, APIs will be treated as standalone products rather than mere technical components.
2. AI-Powered API Management
AI-driven analytics will provide insights into API performance, security threats, and usage patterns, enabling organizations to make data-driven decisions.
3. Serverless Computing and APIs
Serverless computing platforms like AWS Lambda and Azure Functions are gaining popularity. These platforms allow developers to build APIs without managing servers, leading to greater scalability and cost-efficiency.
4. Microservices and API Decomposition
As microservices architecture becomes more prevalent, APIs will be decomposed into smaller, more specialized components. This granular approach allows for greater flexibility, easier maintenance, and faster development cycles.
5. Enhanced Security Measures
With the growing importance of APIs, security will remain a top concern. Future trends include integrating advanced security measures like zero-trust security, OAuth 2.1, and continuous security monitoring. Organizations will prioritize API security in their life cycle management strategies.
