Hello Hemant, Thanks for reaching out to us.
Adding labels on a keyword can be done using the AdGroupCriterionLabel. As per that guide, the fields for the AdGroupCriterionLabel are Immutable, thus updating keyword labels are not feasible. What you can do instead is to remove the said keyword label using the MutateAdGroupCriterionLabels of the AdGroupCriterionLabelService. You can then create a new label using the LabelService then associate the new label to a keyword using once more the AdGroupCriterionLabelService.
