ActionButton volunteering actions come from VolunteerMatch – the largest source of virtual and in-person volunteering opportunities in the United States. While these opportunities are primarily U.S. focused, you may be able to access opportunities in other countries as well.

Contacting legislators

ActionButton uses several sources to gather contact information for legislators, including the Google Civic API and Communicating with Congress API.

This feature is available for legislators in the US, UK, and Canada.


ActionButton donations rely on an organization’s tax ID (referred to as an EIN) to direct funds to the charity or nonprofit. This feature is available in the US only.

How it works

The ActionButton donations that you build will rely on OrgHunter, which is a Donor Advised Fund. To get this set up, you will need the EIN of your chosen 501c(3) charity. This can generally be found on the organization’s website, or through a service like CharityNavigator, Guidestar, or via the IRS's tax exempt organizations search.

Are there fees?

Yes. In addition to ActionButton’s 3% service fee, OrgHunter, a donor-advised fund (DAF) which powers donations to any 501c(3) via Stripe, collects a 3.5% service fee. Additionally, there is a standard 2.2% + $0.30 credit card transaction cost. Funds donated via OrgHunter are disbursed monthly.

Do donors get receipts?

Yes! Donors will receive a receipt sent from ActionButton, denoting the charity or nonprofit, and the amount donated.
