# Tag Resolve Requests

Tag your address resolve requests with metadata for usage tracking. Tags are appended to the resolve API call (the second request that retrieves the full address when a suggestion is selected).

See [Tagging and Usage Tracking](/docs/guides/tag-and-track.md) for more on how tags work.

## Static Tags[​](#static-tags "Direct link to Static Tags")

* JavaScript
* HTML

```


AddressFinder.setup({

  apiKey: "ak_test",

  resolveOptions: {

      tags: "checkout,web"

  },

  outputFields: {

      line_1: "#line_1",

      line_2: "#line_2",

      line_3: "#line_3",

      post_town: "#post_town",

      postcode: "#postcode"

  }

});
```

```


<form style="max-width: 450px; padding: 10px;">

  <label for="line_1">Address First Line</label>

  <input type="text" id="line_1" />

  <label for="line_2">Address Second Line</label>

  <input type="text" id="line_2" />

  <label for="line_3">Address Third Line</label>

  <input type="text" id="line_3" />

  <label for="post_town">Town or City</label>

  <input type="text" id="post_town" />

  <label for="postcode">Postcode</label>

  <input type="text" id="postcode" />

</form>
```

## Dynamic Tags[​](#dynamic-tags "Direct link to Dynamic Tags")

Use `setResolveOptions` to update tags after the controller has been instantiated. This is useful when the tag value depends on user context, such as the current page or form.

* JavaScript
* HTML

```


const c = AddressFinder.setup({

  apiKey: "ak_test",

  resolveOptions: {

      tags: "default"

  },

  outputFields: {

      line_1: "#line_1",

      line_2: "#line_2",

      line_3: "#line_3",

      post_town: "#post_town",

      postcode: "#postcode"

  }

});



// Update tags based on which form is active

document.getElementById("form_select").addEventListener("change", (e) => {

  c.setResolveOptions({

      tags: e.target.value

  });

});
```

```


<form style="max-width: 450px; padding: 10px;">

  <label>Tag:</label>

  <select id="form_select">

      <option value="checkout">Checkout</option>

      <option value="registration">Registration</option>

  </select>

  <label for="line_1">Address First Line</label>

  <input type="text" id="line_1" />

  <label for="line_2">Address Second Line</label>

  <input type="text" id="line_2" />

  <label for="line_3">Address Third Line</label>

  <input type="text" id="line_3" />

  <label for="post_town">Town or City</label>

  <input type="text" id="post_town" />

  <label for="postcode">Postcode</label>

  <input type="text" id="postcode" />

</form>
```
