Drip Forms are a legacy feature, being replaced by Onsite Campaigns. If your account is created after November 2022, you will have access to Drip's new Onsite product instead.
You can apply tags and custom fields when someone submits an embedded form in Drip.
Custom Fields
To apply a custom field, use the following syntax to add a hidden field to your embedded form code:
<input type="hidden" name="fields[your_custom_field_name]" value="your custom field value" />
This will automatically add the custom field to any new or existing person’s Profile.
Tags
To add a tag to anyone who submits your form, use the following hidden input:
<input type="hidden" name="tags[]" value="your_tag" />
This code will automatically create a tag for any person, new or existing, who submits this form.
