It works on tickets and changes (approval, solution validation and satisfaction survey) and on problems (solution validation). On installation, the module creates the notifications and email templates with the buttons, which you edit in GLPI like any other template. The templates come ready in six languages (Portuguese, English, Spanish, French, German and Italian), and each recipient gets the email in their own; other languages receive English. The answer is saved in GLPI itself: the approval as if the approver had answered in GLPI, with business rules applied; an accepted solution closes the ticket and a refused one reopens it, with a follow-up; and the rating goes to GLPI's native satisfaction survey.

Each link can be used only once and has a validity period: 7 days by default, adjustable. The solution validation link lasts for the entity's automatic closing delay, when set, and the survey link for the survey duration set in the entity. Once a button is used, the opposite one stops working. The pages open in the recipient's language, and the Layouts tab shows a preview of each one.
