# Customer metafield
**What You'll Need**
* A published form in the **Powerful Form Builder** app.
* A **Shopify customer metafield** already created.\
(*You can create one via Shopify Admin → Settings → Custom data → Customers → Add definition.*)
***
### 📝 Step 1: Create and Use Customer Metafields
1\. From Shopify admin page > go to store **Settings** > click **Metafields and metaobjects**
2\. Click **Customers** > add a customers metafield or use an existing one.
For example: the key is **custom.gender** > copy the **Namespace and Key**
Click **Add definition** (or similar) to define a new custom field. You’ll need to specify:
* A **name** (e.g. “Birthday”, “Preferred Language”, “VIP Tier”, etc.)
* A **namespace & key** (internal identifiers for Shopify)
* A **content type** (text, number, date, boolean, etc.) — choose based on the data you want to store.
* (Optional) Description — helps clarify what this metafield is used for
3. Save it.

### 📝 Step 2: Connect Your Form Field to the Metafield
1. Go to Powerful Contact Form Builder app > click **Forms** > open a form you want to edit
2. Click **Settings** > enable **Shopify** and click on **Shopify** option
3. Map form field with metafield.Select the shopify attributes (on the right) to map with form fields (on the left). For example the **Last** **name** field of the form should be mapped with Shopify **last name** attribute.
⚠️ **Note**: **Email** field on the form is required to be mapped with **email** attribute of Shopify.
4. Tick on checkbox **Set metafields for created customer** > map form field with metafields.
Click **add mapping metafield row** to add more
You’ll see two dropdown lists:
* Left side = your **Form fields**
* Right side = your **Shopify metafield definitions**
Example mapping:
| Form Field | Shopify Metafield |
| ---------- | ----------------- |
| Gender | custom.gender |
| Hobby | custom.hobby |
| Number | custom.number |
5. Click **Save** to apply your metafield mappings.

### ✅ How It Works
When a customer fills out the form and submits it: The data from the field you linked will be automatically saved to their **Shopify customer metafield**.
#### Example Scenario
Your form includes a **Gender** field:
* Male
* Female
* Others
You mapped this field to a Shopify metafield:\
**Namespace.key = custom.gender**
A customer fills in the form and selects:
> **Gender: Male**
Then they submit the form.
The app will:
1. Create or update the Shopify customer profile
2. Save the customer’s answer directly into the metafield you set up
So inside Shopify → Customers → (This Customer):\
You will now see:
**Gender = Male**
