If you’re using one of Drip’s embedded forms, and would like each subscriber added via that form to have a specific custom field or tag, use the following syntax to add a hidden field to your embedded form code:

Custom Field

<input type="hidden" name="fields[your_custom_field_name]" value="your custom field value" />

You do not need to create this custom field in advance – it will be automatically created on any subscriber, new or existing, who submits this form.

Tag

To add a tag with value “tag1” to any subscriber who submits this form, use the following hidden input:

<input type="hidden" name="tags[]" value="tag1" />

If you’d like to add 2 tags, add 2 hidden inputs:

<input type="hidden" name="tags[]" value="tag1" />
<input type="hidden" name="tags[]" value="tag2" />
