MuleSoft provides a lightweight enterprise service bus (ESB) and integration framework called Mule. It is scalable and can be integrated with any legacy systems and since, the framework is built on a Java platform, the platform can interact with other platforms including web services and that is one of the main reasons why Salesforce bought Mulesoft.
I was working on one of the projects with Mulesoft using salesforce new feature which was released in winter 22 release known as Salesforce external services. In this article I will cover how to design/create your first Mulesoft API using Mulesoft API Designer and Integrate it with salesforce external service. Before going further I will first give you a brief about Mulesoft supports tools and Salesforce External Service and then we will discuss step by step on how we can integrate Mulesoft with Salesforce.

What are different Mulesoft Supporting Tools
MuleSoft is an integration platform which integrates different tools using APIs. As Mulesoft developer, you will work on any platform. Mulesoft basically supports 5 different types tools mentioned below:
- Anypoint Studio: It is an Eclipse-based graphical interface for developing, testing, and running Mule flows.
- Anypoint Enterprise Security: It provides Mule applications with secure access and transactions.
- Mule Healthcare Toolkit: It provides processing of HL7 standard messages needed by healthcare organizations
- Mule Management Console: Mule Manager is a user interface that enables deployment to the Mule Repository and clusters at runtime.
- Mulesoft Cloudhub: It is an integration platform that connects apps, data, and devices with integration connectors. It is also known as Integration platform as a service (iPaaS) for building and deploying Mulesoft applications.
What is Salesforce External Service
Using salesforce external service you can integrate Salesforce orgs with external APIs without writing a single line of code. Also, you can create invocable actions in Salesforce and use them in a flow to interact with an external API source.
To learn more about salesforce external service you can follow the below links:

- Trailhead Module On Salesforce External Service: https://trailhead.salesforce.com/en/content/learn/modules/external-services/get-started-with-external-services
So, basically we will import Mulesoft API build with API Designer with salesforce external services for Mulesoft. MuleSoft External Services can only be used with a MuleSoft license or trial account.
Salesforce Mulesoft Integration Flow Diagram
As you can see this flow diagram consists of four steps, but we will only discuss steps 1, 2, and 3. In my next article, I will discuss step 4 along with that we will also create a Mulesoft application and deploy it with Cloudhub.
How To Design Your First API Using Mulesoft API Designer
Using API specifications, developers can specify how APIs interact and integrate with the external API or system. RAML and OAS are 2 of the API specification languages used to describe and visualize how API interactions work. In this article, I will use API Designer to create a RAML specification that will be published to Mulesoft AppExchange.
Step 1: Setup A Free Trial Account With Mulesoft
As I mentioned above MuleSoft External Services can only be used with a MuleSoft license or trial account. In order to create your first API, we have to create a free trial account with Mulesoft using the below link.
Step 2: Create Your API Using Design Centre
Once you are logged in to Anypoint Mulesoft Platform, Navigate to the Design Center by click on the Navigation menu on the upper left corner or you can also click on this link: https://anypoint.mulesoft.com/designcenter it will redirect you to design center project page. Once you have navigated to the Design Center, click the Create New button, and select Create API Specification as shown on the below video.

How To Import Mulesoft AnyPoint Studio API Using Salesforce External Service For Mulesoft
Salesforce external service for Mulesoft is a new feature of winter 22 release and if you are not able to see this option on your salesforce org, I would recommend you to create a case with salesforce. In order to access to feature login to your salesforce account and then go to Setup | QuickFind | External Service | Click on “New External Service” (also added a screenshot for your reference)
Select an API Source | click on “From Mulesoft Anypoint Platform” | Click on Next (added a screenshot for your reference)
Automatically it will populate your named credentials, select your Available Named Credentials. As shown in the below screenshot I have selected SFDC247Mulesoft, which we have created above.
Then you have to select the API which will be imported automatically from your anyPoint studio platform. So, as you can see below, we have created an API “Get Accounts Api” and its populated automatically. So, I have clicked on the radio button and then you have to provide external service details.
So, in this case I have provided below deatils:
|Choose your selected Named Credential For Mulesoft
|Give a user friendly description
Once the above details are filled you have to click on Save & Next
Select the API Endpoint resource and then click on Next
Finally, you will see the schema of your API with the output parameters and click on Done
On the below screenshot you can see that you have successfully imported GetAccountsApi which we have created above.
Thus, you are now able to import Mulesoft API into salesforce and you can use it in Flows/ExternalServiceCalls. I am really sorry for lot of images that I have added but, i wanted to make a detailed article on How to create your first Mulesoft API using AnyPoint Platform and retrieve those API’s using salesforce external service.
If you want to build or test any Mulesoft API, you can also use the Mulesoft Postman Collection. I have added a screenshot for your reference.
