Attributes
An attribute is a fact about a person, such as city, plan or birthday. System attributes exist already; custom attributes are created as data arrives. Attributes can be nested arrays.
Events
An event is something a person did, with a name, a time and properties. signup_completed and purchase_completed are events. Events trigger journeys and feed funnels.
Transactions
A transaction is an order or a payment, in the currency you set for the workspace. Lifetime value and order count are built from transactions and are not tied to e-commerce.
Frequently asked questions
Can I lock the schema?
Yes. Locking stops unexpected fields from being added.
Where is an attribute used?
