True or False: Updating an array-type custom attribute only costs one data point, no matter how many properties are added.

The statement is false because updating an array-type custom attribute does not simply cost one data point regardless of the number of properties added. Each time an array-type custom attribute is updated, the total size of the data being sent can impact the number of data points consumed. Specifically, if you are modifying the array to include more elements, the overall data size increases, leading to higher costs in terms of data points utilized.

In Braze, data point consumption depends on the complexity and size of the data being sent. The more extensive the data (in this case, the more properties or items added to the array), the more data points will be consumed. Thus, it's essential to consider the size of attributes when performing updates to ensure accurate tracking of data usage within your account.
