To submit a match request, navigate to "My Impacts" from your user dashboard. If your impacts are eligible for a match then you'll see them populate on the "Request Gift Matching" and "Request Volunteer Matching" tabs. You will also see whether they are eligible for a match via the match eligibility badge.
On the "Request Gift Matching" tab, you can select single or multiple impacts given to the same organization to request for a match. Impacts given to groups other than the one you selected initially will be greyed out until you complete your current match request.
Your match request will be submitted after you hit the Request Match button! You can go back and submit additional match requests.
