**Create a tag** · Changes data

Create a new tag on a website so you can label leads with tag_lead. The name is stored in upper case and must be unique on the website (a duplicate returns 'Tag text already exist'). websiteId comes from list_websites. Check list_tags first to reuse an existing tag. Returns status 'Successful' and tagId.
