This API allows you to attach custom properties to any identified users from your servers, such as Sign Up Date (in ISO8601 format), Total # Transactions Completed, or Total Dollars Spent.

Note that Heap will create a new property if it doesn’t already exist, and will overwrite the previous property if one already exists with the same name. If the identity does not exist in Heap, Heap will create it as a user but with no events. Once events come to the user with the same Identity, the two will be merged under one user profile.

Currently, heap.AddUserProperties calls cannot be named all casings of id (ID,Id,iD,id) as it clashes with internal variables.

Our Looker Actions integration allows you to quickly import property data into Heap. See the Looker Actions Integration guide to learn more.
