# Trigger Shopify Flow on product metafield changes

We will assume the following scnario to understant how we can create product metafield update trigger from the **Workflow Trigger Extensions** app

---

## Scenario: Production status changes, right team is notified each time

A manufacturer tracks each stage of production in a metafield. Every status change triggers a notification to the team responsible for that stage.

The metafield `custom.production_status` is updated to a new stage value.

A condition branch reads the new status and routes to the matching action. `in_production` , `quality_check` or `ready`

Each status routes to a different team: production floor, QA team, or fulfilment, so only the relevant people are contacted at each stage.

## How we will make this flow

We can make this flow by following these 2 steps:
1. Add trigger to Product Metafield
2. Create the Shopify flow

You can also see these steps in the demo video below (video has no voice):

### 1) Add trigger to Product Metafield

First you have to add trigger to the desired metafield for product, you can follow the following steps.
- Create the Product Metafield Trigger, from the app dashboard → Setup Guide → `Product and Colleciton Triggers` , if you do not see the Setup Guide, you can go to app metafield triggers page of the app.
- Then create the trigger pressing the Add Trigger button
- hen select the resource type Product and search for the desired metafield on which you want to add the trigger, select and press Add Trigger button

### 2) Create the Shopify flow

Create the Shopify flow to take action (alert the respective team based on status value)

I have attached the same flow file here, you can download, import and use for reference (At the end of the page)
- Create the blank flow and select the **Metafield Update** trigger from the **Workflow Trigger Extensions**
- Then record the event by clicking the record event and then in a new tab, update the product metafild (Production Status) to preview the payload to be used in the workflow. Click select text event and record events.
- After pressing the record events button, go to new tab and update the product metafield (Production Status).
- You will be able to see the payload and based on this data, you can perform any action
- Now check if the resource type is `PRODUCT` AND depending upon the metafield (production status) value, send an email to inform the corresponding team. In the email message, I have used the [remove filter](https://shopify.github.io/liquid/filters/remove/) to remove `gid://Shopify/Product/` from the product [GID](https://shopify.dev/docs/api/usage/gids). By removing this part, now we can see the clean product id in the emails.
- Email looks like this:
