Custom Fields
Custom Fields let you add task-specific fields to extend the standard Task object with additional information your team needs to capture.

How it works
Standard fields (Task Title, Status, Priority, Due Date) are built-in and cannot be modified. Custom fields are added on top of these and can be configured with their own field type, lock behavior, and access rights.
Step 1: Open Standard Object Fields
-
Go to Settings
-
Select Standard Objects
-
Select Standard Object Fields
-
Click the Tasks tab

Step 2: Add a custom field
-
Click Tasks Custom Field then + Add Field
-
Fill in the field details:
-
Field Label — the display name for the field
-
Field Key — auto-generated from the label, used as the system identifier
-
Field Type — select from: Text, Long Text, Number, Date, True/False, Select, Multi Select, Status, Tag, User, Group, Stage, Related Object, or Related Object (Multiple)
-
Required Field — toggle on if this field must be filled when creating a task
-
Lock Behavior — controls whether the field can be edited when the task is locked (e.g., when a deal is Won)
-

Step 3: Save the field
Click Save Field to create the custom field.
-
Field permissions (view and edit rights) can be configured after creation using the Access Right button on each field
-
Standard fields are built-in and cannot be added, removed, or modified
