Connect Sevastack to your website and systems
Pick the option that matches what you want to do. Most NGOs only ever need the website widgets.
Website widgets
Any NGO. No developer needed.
Copy one snippet into WordPress, Wix or any website: a volunteer sign-up form, your upcoming activities, an impact counter, a donation form or your campaigns.
REST API
Developers, CSR partners, agencies.
Add volunteers, register them for activities, mark attendance, log hours in bulk and pull hours reports from your own systems.
Webhooks
Zapier, Make, Google Sheets, your CRM.
Get a signed request the moment a volunteer signs up, registers, attends or logs hours — no polling.
