The API Connect components deliver a consistent user experience throughout the API lifecycle. Modifications in one phase of the API lifecycle are automatically mirrored in the other API Connect components. integratingBelow are the IBM API components and their definitions:
API Connect is a service that connects APIs. The API Connect on-premises cloud is managed via the Cloud Manager component. The Cloud Administrator uses this UI to manage (alter, move, remove, restart, and reboot). It can keep an eye on the cloud's health. Define and manage the API development provider organizations.
API developers construct draft API definitions for REST and SOAP APIs and OAuth provider endpoints for OAuth 2.0 authentication, using the API management features in the API Manager or the CLI. The API definitions can be customized to add the API to a Product, add a policy assembly flow (to alter requests/responses), and define security choices and other settings, among other things. APIs can then be evaluated locally before being published to confirm appropriately specified and implemented.
The API Manager is a user interface that makes promoting and tracking APIs bundled as part of Products and Plans easier. API providers can control the availability and visibility of APIs and Plans and move products through their lifecycle. In the API Manager, Catalogs and Spaces are built as staging targets for publishing APIs, Plans, and Products to consumer organizations. API providers can publish their Products to make those Products public on a Developer Portal for external discovery by staging them to Catalogs or Spaces.
API Gateways enforce runtime policies to secure and regulate API traffic and provide endpoints that expose APIs to calling applications and assembly functions that allow APIs to interface with other endpoints. All API interactions are also logged and reported to the API Connect analytics engine, which allows for real-time and historical analytics and reporting.
API Connect has a containerized runtime that you may use to run applications and API implementations.
A containerized runtime environment provides a lightweight deployment site for APIs and applications. A container is a file system that contains everything a program needs to run, including code, runtime, system tools, and system libraries. To run API Connect-managed APIs and apps, you can utilize Docker Swarm or Kubernetes containers.
Application developers can use the Developer Platform to explore, discover, and subscribe to APIs using a configurable self-service web-based portal. When API providers publish APIs in the API Manager, the APIs are made available in the Developer Portal for application developers in consumer companies to discover while using.
API Connect allows you to filter, sort, and aggregate data from your API events. This information is then provided in connected charts, tables, and maps to assist you in managing service levels, quotas, controls, security rules, community management, and trend analysis.
You may create, promote, utilize, and track APIs from an on-premises cloud. An on-premises cloud comprises various appliances, each of which has specific server-type APIs. The number of servers in your cloud dictates how the task of managing, analyzing, routing, and storing data is distributed.
API Connect comes with both a command line and a graphical user interface. For everyday tasks, provider and consumer groups employ different interfaces.
The developer toolkit includes a command-line interface (CLI) and a graphical user interface (API Designer). LoopBack, an open-source Node.js framework, is used.
An API developer can use LoopBack to establish a Node.js application, connect to a data source to be consumed, such as a back-end database or a REST API, and then expose the application as a REST API by generating a model definition. A LoopBack model provides a REST API by default and defines the API’s application data, validation rules, data access capabilities, and business logic.
A REST API definition can then use this REST API developed using the API Designer or CLI and made available to your users. The API and its related application, implemented as a LoopBack project, must be published to launch the project. Local testing of LoopBack projects is also possible. The LoopBack project architecture is depicted in the diagram below:
SOAP is a technology that was created before the introduction of REST. The primary goal of SOAP was to make it simple for programs written in a variety of platforms and programming languages to share data. The acronym SOAP refers to the Simple Object Access Protocol.
REST is designed to work with media components, files, and even objects on a specific hardware device. A RestFul web service is defined using the REST principles. A Restful service would use the standard HTTP verbs GET, POST, PUT, and DELETE for working with the required components. Representational State Transfer (REST) is an acronym for Representational State Transfer.

HTTP may be found all across the internet. When you use a URL in your browser to hunt for information or a resource on the internet, an HTTP request is sent from the client to the web server, and the HTML content returns in the response. It's vital to highlight that applications use the RESTful API, whereas humans usually use websites.
To request data from any destination website, the data must be in a browser-readable format, such as HTML, but the REST API's response will be in XML/JSON or another similar design. Because REST is motivated by HTTP, it can be considered the REST's pillar of strength and structure. HTTP is a TCP/IP-based connection protocol used to transfer data across the Internet, as you may know. Even though it relies on HTTP, REST does not connect to the internet and does not reply when accessed using a web browser.
LoopBack is an API development framework that connects APIs to backend data sources. Built on top of Express, it can simply produce a fully functional end-to-end REST API that any client can invoke from a data model description.API Explorer, LoopBack's built-in client, is included. We'll utilize this since it makes it easy to observe the effects of our effort and allows us to focus on the API itself in our example. To follow along, you'll need Node installed on your computer.
DataPower API Gateway and DataPower Gateway are two IBM API Connect gateways (v5 compatible). The DataPower API Gateway was created with APIs in mind and the same level of protection as the DataPower Gateway (v5 compatible). Whereas DataPower Gateway (v5 compatible) was designed for versatility, DataPower API Gateway is tailored to the API use case, resulting in improved performance. DataPower API Gateway was created with the cloud in mind. Use this gateway to offer APIs operating in a public or private cloud.
Creating a REST API (Representational State Transfer Protocol)
Complete the following steps to add and define a REST API:
1. Make a folder for your API and Product definitions and navigate it in a command window.
2. Change to your LoopBack project's directory and type the following command.
The console then displays the following message after a bit of pause:
API Designer will open your web browser and show you the login screen if you haven’t logged in recently.
3. Use the proper technique to log into APIConnect Designer.
4. Select New API from the drop-down menu.
5. To create a REST API definition, fill in the blanks.
6. Click Create API if you haven't yet added a product.
7. If the API Editor help screen opens, click the sentence Learn more about building APIs to return to the main screen, or click Got it! To return to the previous screen.
8. Click Lifecycle in the sidebar to bring up the Lifecycle panel. Make sure the Enforced, Testable, and CORS toggles are all turned on, as shown in the screenshot below:
9. Click Security Definitions in the sidebar to bring up the Security Definitions panel. ClientIdHeader security definition exists, and Option 1 is active with the client header in the Security section (API Key).
10. Select Paths from the sidebar to open the Paths panel. By clicking the Add Path icon, you can create a new path. The icon for creating a path.
11. Replace the default path segment in the Path field with /details. When an operation is called, this path segment is appended to the API's URL.
12. Your Path already contains a single GET operation. To expand the settings dialogue, click the GET button.
13. As shown in the table, provide the operation a summary and a description.
14. The Definitions panel will appear when you click Definitions in the sidebar. By selecting the Add Definition icon, you can create a new Definition. The symbol that says "Add Definition."
15. By selecting new-definition-1, you may make your new definition even more comprehensive. Enter the address and a description of the address object's format in the Name field.
16. Configure the Properties definition as shown in the table using the same Definitions panel. After altering the default property, click Add Property and modify the default values to add new properties.
17. By clicking the Add icon, you may add a second definition. In the Definitions panel, click the Add definition icon.
18. Name the definition branch and write The format of the branch field in the Description field.
19. Create new properties and change the default property in the branch definition to have the properties given in the following table. By clicking Add Property, you can create new properties.
20. To access the Paths panel, click Paths in the sidebar. To extend the available options for the /details Path, click GET. By choosing the Schema field and selecting a branch from the drop-down list, include the branch definition in the GET operation Status Code 200 response.
