### Start a MESA Workflow From Shopify Flow

MESA can receive Customer, Order, and Product data from Shopify Flow.

1. In MESA, create a new workflow using a **Shopify Flow** trigger.

2. In Shopify Flow, create a workflow with the **Add action** button. Then, select the corresponding MESA action from Step 1.

If you select the **Send to Mesa** action in Shopify Flow, you can copy the **Workflow Key** from your MESA workflow's **Dashboard** tab.

### Start a Shopify Flow Workflow From MESA

1. Add a Shopify Flow action in MESA.

2. Complete any required fields referencing an ID. In most cases, you want to use [MESA's Variables feature](https://docs.getmesa.com/workflow-builder/fields/variables) and locate the variable that represents the entity's ID (e.g. Product ID, Customer ID, Order ID).

To send custom data to your Shopify Flow, select the [**Send Custom Data to Shopify Flow**](https://docs.getmesa.com/connect/shopify-flow#send-custom-data-to-shopify-flow-step) step.

3. Create a new workflow in Shopify Flow.

4. Within Shopify Flow's " **Start When**" block, select a **MESA Action**.

## Technical Notes

### **Send Custom Data to Shopify Flow step**

Use this step to send unstructured or custom data to your Shopify Flow. This will allow you to define a key-value pair array (similar to the Line Items properties), and you can read this in your Shopify Flow.

For example, we want to send a Shopify Order's Name and ID to our Flow. We can set this up by doing the following.

In Shopify Flow, we can reference the data as `{{ custom_data.data[0].value }}` and this will represent the Order's Name.

### Send Custom Data from Shopify Flow to MESA

To send custom data from Shopify Flow to MESA, create a workflow in Shopify Flow with a **Send to Mesa** action.

Next, open the Send to Mesa action, enter the desired key, then select **Add a variable** to see the available data.

For example, this Send to Mesa action will send the contact email from Shopify Flow to MESA.

Your payload should follow a similar structure to the one shown above.

### How to use Data from Shopify Flow

When sending Orders, Customers, and Products from Shopify Flow, there must be a previous step to designate the object's ID.

This Shopify Flow workflow will send the Order ID to MESA when an order is created.
