Overview

An attribute’s value type determines what it can hold and how you can filter it. Text supports text matching, numbers support comparisons, and dates support time ranges. Reference attributes let you use attributes from related objects. Choose the type when creating an attribute. The type is fixed after creation.

Text and identifiers

Numbers and choices

Define select and multiselect options when creating the attribute. You can add options later.

Dates and times

Contact and location data

Structured data and references

JSON

A structured JSON object containing nested data. Individual attributes are useful when each value needs its own name, type, and validation rules.

Relationship

A reference to records in another object. Configure the related object and whether each side can reference one or many records. See Relate objects. For programmatic setup, use the Data API’s Create attribute endpoint.
