How it works

2 steps to start triggering custom code from your Shopify Flow workflows

Retrieve data from Shopify Flow

App connector: Shopify Flow • Time to complete: 0 minutes (Auto-configured)
Why this matters: This trigger receives data from your Shopify Flow workflow and makes it available to process with custom code logic.

This step automatically captures whatever data your Shopify Flow workflow sends to MESA when it triggers this action. You don't need to configure anything here - it simply receives the payload from Flow and passes it to the next step. The trigger activates whenever your Flow workflow reaches the action that calls this MESA automation, bringing Flow data into MESA's more powerful processing environment.

Custom Code

App connector: Code • Time to complete: 0 minutes (Auto-configured)
Why this matters: This step executes your JavaScript code using the data from Shopify Flow, giving you unlimited processing power beyond Flow's built-in actions.

This is where you write custom JavaScript to process the data from your Flow workflow. You can access all the Flow data through the input variables and perform complex logic, calculations, API calls, or data transformations that aren't possible in Flow alone. Write your code in the editor, test it with sample data, and it will execute automatically each time the workflow runs. Your code can return data, make external API calls, or trigger additional actions.

// Example: Log the Flow data and perform custom processing
console.log('Received from Flow:', input.shopify_flow);

// Access Flow data
const flowData = input.shopify_flow;

// Perform custom logic here
// Example: Calculate metrics, call external APIs, format data

// Return processed results
return {
  processed: true,
  timestamp: new Date().toISOString(),
  originalData: flowData
};

Make it your own!

Customize this workflow even further:

Add conditional logic branches
Create smart decision trees in your custom code that choose different actions based on Flow data, like processing high-value orders differently than regular orders.
Connect to external APIs
Use your custom code to send data to third-party services like analytics platforms, CRM systems, or marketing tools that don't have direct Flow connectors.
Transform data for specific formats
Process Flow data into custom formats required by your business systems, such as converting Shopify order data into your accounting software's specific structure.
Store results in data tables
Save processed results or calculations in MESA's built-in database for tracking metrics, building reports, or referencing in future workflows.
