The Track API Method is used to track a contact’s actions by managing tags.

​
Example Requests:

Add tags: 
{
  "addTags": ["blogger", "female"]
}
Add and remove tags: 
{
  "addTags": ["paid user"],
  "removeTags": ["trial user"]
}
Automation rules can be triggered based on tag additions or removals, e.g.:
  • On user registration tag, start onboarding drip campaigns.
  • On account upgrade, start account expansion drip campaigns.
  • On removal of the trial user tag, initiate upsell campaigns.
