# Start with Microflow in ONEWEB

This section introduces the basic steps required to **create, design, test, and deploy a Microflow** in ONEWEB.\
Microflow is a key integration component used to implement service‑oriented logic and connect applications with internal or external systems.

***

### Prerequisites

Before creating a Microflow, ensure that:

* You have access to **AppSpace**
* An application already exists, or you are ready to create a new one
* You have the required permissions to create and manage Microflows

***

### Step 1: Create or Open an Application in AppSpace

1. Log in to **AppSpace**
2. Either:
   * Create a new application, or
   * Open an existing application
3. Navigate to the **Application Components** page

All Microflows are created and managed **within the context of an application**.

***

### Step 2: Create a Microflow

Within the application:

1. Choose the **Microflow** option from the components menu
2. Click **Create Microflow**
3. Enter the required details (such as name and description)
4. Confirm creation

Once the Microflow is created and the required permissions are generated, AppSpace automatically **redirects you to the Microflow Designer**.

***

### Step 3: Design the Microflow

In **Microflow Designer**, you can now design the integration logic by:

* Adding **Activity Nodes** such as:
  * Web Service Task
  * Database Task
  * Java Task
* Defining execution flow and conditions
* Mapping input and output parameters
* Adding error handling and timing controls (Error / Timer events)

The Microflow Designer provides a **visual, drag‑and‑drop environment** for building integration logic.

***

### Step 4: Simulate the Microflow

Before deploying, Microflows can be **simulated** to validate logic and data flow.

Simulation allows you to:

* Test execution paths
* Verify parameter mapping
* Detect configuration or logic issues early

This step helps ensure correctness before deploying to a real environment.

***

### Step 5: Deploy the Microflow

After successful simulation, the Microflow can be deployed:

* Export the Microflow if required
* Deploy it to the target **runtime environment**
* Make it available for invocation by:
  * UI components
  * Other Microflows
  * Processes
  * External systems (if exposed via runtime server)

Deployment enables the Microflow to function as a live integration service.

***

### What You Will Learn in This Section

In this section, you will learn how to:

* Create an application in AppSpace
* Create and design a Microflow from scratch
* Use Microflow Designer to build integration logic
* Simulate Microflows for testing
* Deploy Microflows to a runtime environment

These steps form the foundation for developing **robust, reusable, and deployable integrations** using ONEWEB Microflow.

***

### Summary

Starting with Microflow in ONEWEB involves a clear and guided workflow:

1. Create or open an application in AppSpace
2. Create a Microflow within the application
3. Design integration logic using Microflow Designer
4. Simulate and validate the flow
5. Deploy the Microflow to runtime

This structured approach allows developers to build **service‑based integrations efficiently**, making Microflow a central element of ONEWEB’s integration architecture.
