# Setup Platform Events and Flows
To set up an Order Event flow, it will depend on whether you use [Limio for Salesforce](https://docs.limio.com/integrations/salesforce-integrations/managed-package-overview), an add-on for order management in Salesforce, or not.
Limio for Salesforce comes with a pre-made **Salesforce Lightning Flow** to map your **Salesforce Platform Events** to your Salesforce data. Otherwise, with a few extra steps, you can create a Lightning Flow from scratch.
If you are not familiar with Salesforce Platform Events and Salesforce Lightning Flow, we recommend you do the following:
* [Platform Events Basics](https://trailhead.salesforce.com/content/learn/modules/platform_events_basics)
* [Flow Builder Basics](https://trailhead.salesforce.com/content/learn/modules/flow-basics)
Below you'll find a step-by-step guide for both methods.
* [If you have the Limio for Salesforce managed package installed](https://docs.limio.com/integrations/populating-salesforce-data/platform-events-flexible/setup-platform-events#if-you-have-the-limio-for-salesforce-managed-package-installed)
* [If you don't have Limio for Salesforce](https://docs.limio.com/integrations/populating-salesforce-data/platform-events-flexible/setup-platform-events#if-you-dont-have-limio-for-salesforce)
## **If you have the Limio for Salesforce managed package installed:**
1. **Access the Setup Menu**
* Go to **Setup** in Salesforce.
2. **Navigate to Flows**
* In the Quick Find search bar, type **"Flows"** and select the **Flows** page from the search results.
3. **Locate the Flow**
* Find the flow named **Listen to Limio OrderEvent\_\_e**.
4. **Review the Transform Element**
* Within the **Listen to Limio OrderEvent\_\_e** flow, you will find a transform element named **Map values from event to Object record**.
* Open this transform element to review its configuration:
* **Source Data**: Set to **i42as\_\_OrderEvent\_\_e**, with a list of its fields displayed.
* **Target Data**: Set to the **Asset** SObject (or any other object like Opportunity), also showing a list of its fields.
* If you click on a field in the **Source Data**, you can map it directly to the corresponding field in the **Target Data** (Asset SObject).
5\. **Activate the Flow**
* By default, this flow is inactive.
* To activate the flow after you configured the target object and fields mapping, click **Activate** in the top-right corner of the screen.
## **If you don't have Limio for Salesforce:**
If you don’t use **Limio for Salesforce**, you can still set up a Platform Event-Triggered Flow to process events and create records in Salesforce. This requires creating your own custom Platform Event and configuring the flow to handle the data accordingly. Additionally, you’ll need to coordinate with Limio to ensure system publishes events to your Salesforce org.
Follow these general steps to implement the solution:
1. Create a Platform Event in Salesforce
2. Create a Platform Event-Triggered Flow
3. Reach Out to Limio Support
**Steps to create Platform Event in Salesforce:**
1. **Access the Setup Menu**
* Go to **Setup** in Salesforce.
2. **Navigate to Platform Events**
* In the **Quick Find** search bar, type **"Platform Events"** and select the **Platform Events** page from the search results.
3. **Create a New Platform Event**
* Click the **New Platform Event** button.
* Fill in the standard fields.
* Click **Save** to create the Platform Event.
4. **Add Custom Fields to the Platform Event**
* After saving, you’ll be redirected to the Platform Event’s detail page.
* Click **New Field** to add custom fields to the Platform Event.
* Choose the field type (e.g., Text, Number, Email, etc.).
* Define the **Field Label**, **Field Name**, and any necessary field attributes (e.g., length, required status).
* Click **Save** after creating each custom field.
Steps to create a Platform Event-Triggered Flow from scratch:
1. **Access the Setup Menu**
* Go to **Setup** in Salesforce.
2. **Navigate to Flows**
* In the Quick Find search bar, type **"Flows"** and select the **Flows** page from the search results.
3. **Create a New Flow**

4. **Select the Flow Type**
* In the Flow Type selection screen, choose **Platform Event-Triggered Flow** and click **Create**.
5. **Choose the Platform Event**
* In the **Start** element:\
a. Click **Edit** (pencil icon) next to the **Platform Event** option.\
b. Select the desired **Platform Event** (e.g., **Express\_Event\_\_e** created above or any custom Platform Event available in your org).\
c. Click **Done**.
6. **Add a Transform Element**
* Configure the transform element as follows:\
a. **Source Data**: Select the **Platform Event** fields.\
b. **Target Data**: Select **Data Type > Record and** **Object** > **Account (or any other target object like Opportunity)**.\ \
c. Map the fields from the **Platform Event** to the corresponding fields in the object. For example:
* **Platform Event Field (e.g., Name)** → **Account Field (e.g., Name)**
* **Platform Event Field (e.g., Email)** → **Account Field (e.g., Email\_\_c)**
7. **Add a Create Records Element**
* Add the **Create Records** element to the canvas.
* Configure the element as follows:\
a. **Label**: Give the element a name (e.g., **Create Account Record**).\
b. **Record**: Select the **Account** object.\
c. **Create a Record from These Values**: Use the values mapped from the Platform Event in the transform step.
8. **Save the Flow**
* Click **Save** and provide a name for your flow.\
\
9. **Activate the Flow**
* Once saved, click **Activate** in the top-right corner of the screen to make the flow active and ready to handle incoming platform events.
