MuleSoft Composer provides a way to handle errors and notify users when something goes wrong in

a flow. Aside from viewing errors on the Flow Details page, MuleSoft Composer can also send

notifications to alert users about the errors.

Flow Error Handling: When an error occurs in a MuleSoft Composer flow, the error is logged and

visible on the Flow Details page.

Email Notifications: MuleSoft Composer can be configured to send notifications to a specified email

address. This allows users to be promptly informed of any issues without having to constantly

monitor the Flow Details page.

Configuration: This can be set up in the MuleSoft Composer settings, where an email address can be

configured to receive these notifications.

When an RPA process involves a User Task that can take a significant amount of time (up to 24 hours)

to complete, it is best to use a follow-up mechanism to handle the results once the process is

finished:

Second MuleSoft Composer Flow:

Create a second MuleSoft Composer flow that is triggered when the RPA process completes. This

ensures that the first flow is not held up while waiting for the long-running RPA process to finish.

The second flow can start based on an event, such as the completion status of the RPA process,

ensuring timely and efficient processing of the results.

Trigger Mechanism:

Configure the RPA process to notify MuleSoft Composer when it is complete, possibly using a REST

API or another integration method.

Best Practices:

This approach adheres to best practices by keeping flows modular and focused on specific tasks,

making them easier to manage and troubleshoot.

 Develop System API for Loyalty System: The first step is to develop a new System API that integrates

with the Loyalty system. This API will handle communication with the external system via the

provided HTTP endpoint.

Reference: MuleSoft API-led Connectivity

 Utilize Existing Customer System API: Use the existing System API for customer data to retrieve

necessary customer information. Combining these APIs ensures a modular approach and reuse of

existing assets.

Reference: API-led Connectivity

 Create Process API: Develop a Process API that combines data from both the Customer and Loyalty

System APIs. This API will process the data, apply business logic to filter the top 10 percent of loyalty

point holders, and format the results.

Reference: Designing Process APIs

 Create Experience API: Develop an Experience API to serve the business consumers. This API will

provide a user-friendly interface for initiating the integration and retrieving the results as a CSV file.

To map fields of the Salesforce Address compound field to the corresponding fields of the NetSuite

Address list in MuleSoft Composer, you need to perform the following task:

Custom Expression in Composer:

Use a custom expression in MuleSoft Composer to combine the individual address-related fields

from Salesforce (Street, City, State, Zip, Country) into a format that matches the NetSuite Address

list.

This custom expression will concatenate the individual simple fields from Salesforce into a structured

format that can be mapped directly to the NetSuite Address list.

Mapping the Fields:

Once the custom expression is created, map the resulting list to the corresponding fields in the

NetSuite Customer entity within the Composer flow.

This ensures that each simple field in the Salesforce compound Address field is correctly mapped to

the respective field in the NetSuite Address list.

 RAML Definition Creation: The first step in creating a new API as per MuleSoft best practices is to

create a RAML (RESTful API Modeling Language) definition in the Design Center. This step is critical as

it outlines the API's structure, endpoints, methods, and data types, providing a clear blueprint for

subsequent development.

Reference: MuleSoft API Design Best Practices

 Project Creation in Anypoint Studio: Once the RAML definition is created, the next step would be to

generate the API project in Anypoint Studio. This IDE allows developers to implement the API logic as

defined in the RAML.

Reference: Getting Started with Anypoint Studio

 Mule Runtime Installation: Installing Mule runtime is necessary for running and testing Mule

applications locally. However, this step is secondary to defining the API’s structure.

Reference: Mule Runtime Installation

 Case Creation in Salesforce: Creating a case in Salesforce is not relevant to the API development

process but may be necessary for support or project management purposes.

In Flow Builder, Run and Debug modes have distinct functionalities:

Run Mode:

Executes the flow as it is, allowing you to see the end-to-end execution based on the latest saved

version.

Typically used to verify that the flow works as expected under normal conditions.

Debug Mode:

Provides detailed information for each step of the flow, including input and output data, and any

errors encountered.

Useful for troubleshooting and identifying issues within the flow, allowing developers to understand

how the flow executes and where problems may arise.

Debug mode is specifically designed to aid in diagnosing and fixing issues by providing a granular

view of the flow's execution.

 API-led Connectivity: MuleSoft’s API-led connectivity approach divides APIs into three tiers: System,

Process, and Experience. Each tier has a specific role in managing data and operations.

Reference: MuleSoft API-led Connectivity

 Experience APIs: These APIs are designed to provide data to end-user interfaces, such as mobile and

web applications. They typically format the data in a way that is easy for the user interface to

consume.

Reference: Experience API Definition

 Process APIs: Process APIs are responsible for orchestrating and executing business logic. They

aggregate, transform, and process data from multiple sources before passing it to Experience APIs or

other downstream systems.

Reference: Process API Role

 System APIs: These APIs provide direct access to core systems and data sources. They handle CRUD

(Create, Read, Update, Delete) operations and expose data from underlying systems.

Reference: System API Role

 Data Aggregation and Transformation: Given the requirements to aggregate and transform data, the

Process tier is the appropriate place. Process APIs handle complex business logic and data

transformation, making them ideal for aggregating data from multiple sources and transforming it as

needed.

The Rate Limiting - SLA-Based policy in Anypoint Platform is designed to control the number of

requests an individual client can make to an API. This policy is highly configurable and allows you to

set specific limits based on service level agreements (SLAs).

Rate Limiting - SLA-Based:

This policy helps protect APIs from being overwhelmed by too many requests by enforcing a limit on

the number of requests a client can make within a specified time frame.

You can define different rate limits for different tiers of clients, ensuring fair usage and protecting

backend services.

Anypoint Platform Rate Limiting Documentation

To address the comprehensive, multi-step process automation requirement at Northern Trail

Outfitters (NTO), a single flow orchestration that uses Stages and Steps is the best solution.

Flow Orchestration in Salesforce:

Stages and Steps: Flow Orchestration allows Salesforce admins to build sophisticated automations by

structuring the flow into Stages (representing different parts of the process) and Steps (individual

actions within each Stage).

User Inputs and Automated Actions: By leveraging Stages and Steps, Salesforce Flow Orchestration

can handle both user inputs and backend automated steps seamlessly, ensuring the entire process is

automated and organized efficiently.

Error Handling and Conditional Logic: It also allows for conditional logic and error handling, ensuring

that the flow can adapt to various scenarios that may arise during the automation process.

Comprehensive Process Automation:

Single User Execution: Given that the requirement specifies that a single user will execute the

process after a case record is created, Flow Orchestration is ideal as it can manage the end-to-end

process in a structured manner, without requiring multiple flows or complex configurations.

Reference:

Salesforce documentation on Flow Orchestration provides detailed insights on how to design and

implement such solutions.
