What is the use of set payload in mule? The payload content changes as it travels through a flow when message processors in a Mule flow set it, enrich it, transform it into a new format, extract information from it, or even store it in a Mule event variable and produce a new payload. Furthermore, what is variable in mule?
What is set payload in dataweave?
The payload can be a literal string or a DataWeave expression. The set-payload component, however, is not recommended for complex expressions or transformations but rather, simple ones, such as selections. You should use Transform Message Component for complex scenarios.
How does mule event travel through the app?
It travels through components inside your Mule app following the configured application logic. A Mule event consists of three components — payload, attributes, and variable — as shown in the figure below. A Mule message contains a message payload and its associated attributes.
What are the components of a mule event?
A Mule event consists of three components — payload, attributes, and variable — as shown in the figure below. A Mule message contains a message payload and its associated attributes.
What are mule messages and variables?
A Mule message contains a message payload and its associated attributes. Variables are Mule event metadata that you can use in your flow. A Message source, such as the Scheduler, HTTP Listener, or On New or Updated File component, triggers the generation of a Mule event and dispatches that event to the flow.

What is the use of payload in MuleSoft?
The payload content changes as it travels through a flow when message processors in a Mule flow set it, enrich it, transform it into a new format, extract information from it, or even store it in a Mule event variable and produce a new payload.
What is the use of set variable in MuleSoft?
The Set Variable ( set-variable ) component is for creating or updating a Mule variable to store values for use within the flow of a Mule app. A Mule variable is part of the Mule event. You can store simple literal values such as strings or messages, message payloads, or attribute objects.
How do you set a payload in an event?
Drag and drop Set Event component from Munit module into the canvas. In the properties of Set Event component write above expression for getting a file in the payload section. Also, write this expression in #[] so that it will be evaluated as a dataweave script by anypoint studio.
What is payload and attributes?
Payload attributes are data elements that don't represent the entity that you resolve, but are worth retrieving when you resolve the entity. They are not used in matching, but they relate to the entity nonetheless.
What are types of variables in Mule 4?
In Mule 4, flows triggered by an event are generated when a trigger reaches the event source of the flow....We have three types of variables:Flow Variables: To store data within the flow.Session Variables: To store data throughout the application.Record Variables: To store data within batch processing.
How do you add two variables in mule4?
In Mule 4, you can easily do this with DataWeave (using the Transform Message component). Just add multiple targets and select "Variable" as output.
What is payload in API?
What is a Payload in an API? The payload of an API is the data you are interested in transporting to the server when you make an API request. Simply put, it is the body of your HTTP request and response message.
What is event processor in mule?
The Set Event Processor allows you to define a Mule Event. This message processor is normally used at the beginning of an MUnit test, to define the first message to send to the flow being tested.
What is DataWeave payload?
The payload contains an array of book objects, one flow variable has a set of currency exchange rates, and the other one a query. The transform filters the first input using the conditions passed in the third input, then performs a map to deal with each remaining object separately.
What is and $$ in Mule?
$$ can be used for getting the key (or index) of the key-value pair. From the online documentation: The index is defined by default as $$ and the value as $. The index refers to the position of a key:value pair when the object is treated as an array.
How many variables are there in Mule 4?
Variable in Mule 4 In Mule 3 we had Flow variables, Session variables and record variable to store the data inside mule flow. But now in Mule 4 this has been changed; session variable and record variable has been removed and there is only Flow Variable.

How do you set multiple variables in Mulesoft?
I have given you code snipit so that you can used it.
There is only one type of variable in mule 4. It's scope is same as session variable. You can use set variable component for setting the variable and then fetch it using # [vars. variableName] in dataweave language.

Static data models have fixed definitions of all the objects and their attributes supported by the target. Most services, particularly relatively simple ones, implement static data models. For APIs using static data models, it is recommended to create Plain Old Java Objects (POJOs) that correspond to the objects exposed through the connector’s operations.
Author : Sanket Kangle. DataWeave is the MuleSoft expression language for accessing and transforming data that travels through a Mule app. DataWeave is tightly integrated with the Mule runtime engine, which runs the scripts and expressions in your Mule app. DataWeave is a functional language in which variables behave just like functions. The general format of a DataWeave script contains 3 ...
Query parameter changed from “Mule” to “Anypoint”, and variable from parent flow is not accessible in child flow. However we can set a new variable in child flow whose scope will be limited to child flow only.
A Mule message contains a message payload and its associated attributes. Variables are Mule event metadata that you can use in your flow. A Message source, such as the Scheduler, HTTP Listener, or On New or Updated File component, triggers the generation of a Mule event and dispatches that event to the flow.

A Mule event contains the core information processed by the runtime. It travels through components inside your Mule app following the configured application logic. A Mule event consists of three components — payload, attributes, and variable — as shown in the figure below.
The modified attributes, payload, and variables are returned to the private flow from where the event moves to the Public_Flow-2. Note that the private_Flow-2 was called from the Public_Flow-2 and the Sub_Flow-2 was called as a part of the private_Flow-2.
Private flow has their own exception handling strategy which allows you to define different threading profiles.
Using flow reference component, the Public_Flow-2 now calls private_Flow-2 as shown in the image above. The table below summarizes the observations:
