# Tagging a subscriber using library

#### Add tags

Our library allow you to easily add tags to subscriber. To do so, insert the following code in your website. Remember that the data must be a valid object.

```markup
<script>
    //add one tag
    sarepush('addTags', {tagName: 'tagValue'}, function (response) {
        console.log(response);
    });
    
    //or multiple tags
    sarepush('addTags', {
        firstName: 'David',
        company: 'Google'
        uniqueId: 123456,
        otherTag: ''
    }, function (response) {
        console.log(response);
    });
</script>
```

#### Remove tags

SAREpush also allows you to remove tags from subscriber. To do so, insert the following code in your website. Remember that the data must be a valid array.

```markup
<script>
    //remove one tag
    sarepush('removeTags', ['firstName'], function (response) {
        console.log(response);
    });
    
    //or multiple tags
    sarepush('removeTags', ['firstName', 'company'], function (response) {
        console.log(response);
    });
</script>
```
