}Get Field Schemas for an Entity
Lists fields for entity, which must be one of accounts, contacts, meetings, opportunities, sequences, or tasks.
Use each entry’s key in filters[].field and sort on the corresponding list endpoint. The allowed_operators array lists the valid values for filters[].condition on that field.
Each entry’s updatable flag indicates whether the field can be written via the entity’s update endpoint; fields with updatable: false are read-only (system-derived or create-only). Custom fields are always updatable, but values on AI auto-filled custom fields may later be overwritten by AI.
Custom fields use custom_field_{uuid} keys. Enum and select fields expose their accepted values under enum_field_settings.allowed_values, and callers must pass the key rather than the display value.
For date and datetime fields the allowed_values are semantic periods used with the is operator. The equals, greater_than, and less_than operators take raw YYYY-MM-DD values instead.
