A Brief on API Development in Mulesoft Anypoint Platform

Mulesoft API management platform offers an umbrella of API design, development, testing, deployment, security, and maintenance in the cloud.

Companies use API integrations to leverage agility in their agile team operations and facilitate faster project delivery. With robust and efficient big data and API management, sharing data with in-house apps, software, tools, and external teams gets easier.

The lifecycle of API implementation in the Mulesoft Anypoint platform includes the following:

API Design

To let developers design easy-to-use APIs for smooth API administration. The API specification will outline endpoints, parameters, configurations, and data structures with authentication and authorization.

API Publishing

This process calls for the API release. Mulesoft API management platform allows users to publish APIs and make them available on the developer portal with support and documentation.

API Gateway

It is a center point between APIs and their users. Developers use the Mulesoft Flex gateway to monitor and control API traffic. It contains features to perform caching, rate limitation, routing, authentication, routing load balancing, and more.

API Security

It limits unauthorized access to API and protects software from security issues or vulnerabilities. It ensures that only allowed parties can use them for secure Mulesoft data integration with features of data encryption, masking, and rate restrictions.

API Analysis

Like data analytics services, the Mulesoft Anypoint platform for API implementation gives insights into historical data, API usage, transactional logs, and other metrics.

Prerequisites Of Building an API With Mulesoft Anypoint API Manager

Implementing Mulesoft API-led connectivity can take you through designing, development, management, monitoring, analytics, and security enhancements.

Hence, it makes sense if you first get more clarity on the significant necessities of API development in Mulesoft before getting started.

There are a few tools and technologies that you need to configure beforehand with these steps:

• Create a trial organization on the Anypoint platform and set up your account using a username and password.

• Download Anypoint Studio version 7.4.1 to build and deploy the Anypoint platform.

• To run REST requests by installing an Advanced REST client from GitHub.

Best Practices for API Development in MuleSoft Anypoint

To begin your API-led journey, you must hire certified Mulesoft developers for successful enterprise data implementation, integration, and management.

In contrast, if you are working on a Mulesoft Anypoint platform development project, you can follow this step-by-step guide on API design and development.

How To Design APIs In Mulesoft?

Keep these steps in mind while designing an API on Mulesoft Anypoint:

Discover Existing API Specifications

Check for existing API specifications to understand how other teams are using them for a purpose like yours.

That will help you decide whether to reuse the APIs or design the desired one from scratch. Take these steps to explore API specifications:

• Go through Mulesoft public Exchange portal to find downloadable API specifications, connectors, and other components. Search for All Types > REST APIs to sort out REST API specifications and see their details.

• Login to Anypoint Platform and click Discover and Share under the Exchange option on its landing page. Select any specification to view the respective API's data types and HTTP requests.

Create New API Specifications

The next step will involve creating your API specification on Mulesoft API Designer. Take this approach to do it:

• Open API Designer and select Create option to open the API Designer editor.

• Select Create API specification next.

• Add a hello-world command for Name and keep other values unchanged.

• Click API Specification next. The API Designer editor will show a sample RAML definition.

• Delete the existing text and add the new RAML command.

Test Your API Specification

Once you're done with the API specification, hello-world.raml, you can request to test its performance and functionality.

Here is how you can test your API specification on Mulesoft API design:

• Open hello-world.raml and click the cross, the X sign beside the Mocking service to enable it. Mocking service is already enabled if you can't see a cross button.

• Search for the API endpoints option and find HTTP requests in green boxes.

• Click GET to view the GET request and other details of the API specification.

• Select Code examples to examine samples for each protocol. Click 404 and 200 under the Responses tab to check the responses in the API specification.

• Disable the Mocking service option once you're satisfied with API specification testing.

Publish Your API Specification

After testing your API specification, you need to publish it on Anypoint Exchange to make it available to other teams in the organization.

Publish your API specification with this approach:

Open hello-world.raml>Publish>Publish to Exchange>Verify to see Valid specification>Publish>Done

How To Build APIs on the Mulesoft Anypoint Platform?

After testing and publishing the API specification, you can start API development in Mulesoft.

Here is a tutorial for beginners to develop APIs using Anypoint:

Step1 - Getting started: Add Anypoint Credentials to Studio

• Open Anypoint Studio and choose Preferences.

• Click Anypoint Studio and Authorization

• Use your Anypoint username and password.

• Choose File>New> Mule Project

• Choose the latest version of the Mule runtime engine hosted within Anypoint Studio for testing.

• Click on From Exchange to Maven tab.

• Navigate to see if the checkbox Scaffold flows from these API specifications is marked.

• Click Finish

Step 3 - API Configuration

• Use Scaffolding on Anypoint Studio to find /greeting endpoint module across the Message Flow tab.

• Right-click the Transform Message tab and delete it.

• View Favorites to see the list of connectors in Mule Palette.

• Click to select the Set Payload option and drag it to the space where you've deleted Transform Message lastly.

• Mark the logic that carries data sent in a response from hello-world API.

Step 4 - Test the API

Open a Studio project that contains your API in the Mule runtime engine and run tests with a third-party client.

• Right-click on the canvas and click Run project hello-world.

• Open a REST client and initiate a GET request. The REST client should display a 200 Ok message with Today the greeting is Hello in the body.

• Right-click again on the canvas and choose Stop project hello-world.

Step 5 - Publish the API to Exchange

Get ready to publish API on the Mulesoft Anypoint platform, so other teams can reuse it as a template.

• Right-click the hello-world project on the package explorer in Studio.

• Click Anypoint Platform>Publish to Exchange.

• Enter project value to fill the empty fields.

• Click Finish and press Yes to proceed further.
