In a mixing bowl combine all sauce ingredients and whisk together.
Transfer chicken to a resealable plastic bag or airtight container.
Pour half marinade over chicken, tightly seal, shake up to mix and refrigerate for at least 4 hours and up to 24 hours.
Pour remaining marinade into a small pot and simmer for 5 to 7 minutes or until slightly reduced (Glaze will thicken as it cools). Remove from heat and set aside.
Once chicken has marinated, pierce 7 to 8 pieces of chicken through each skewer. Repeat until all chicken has been used.
Lightly spray air fryer basket with cooking spray and top with skewers, leaving about½ inch space between each one (cook in batches to avoid overcrowding). Brush each skewer with glaze.
Air-fry chicken skewers at 400˚F for 8 minutes. Flip each skewer and brush with more glaze. Continue to air-fry for an additional 6to 8 minutes or until chicken has cooked through.
Remove skewers from air fryer basket and brush with glaze once more.
Transfer skewers to a serving dish, top with green onion and serve.
