Little Green Light (LGL) website integration: A complete guide for small nonprofits.

For growing grassroots charities and small to mid-sized nonprofits, Little Green Light (LGL) is widely considered one of the most cost-effective and practical donor management systems on the market. However, organizations often struggle when connecting LGL forms to their website, resulting in default forms that look clunky and fail to match brand styling.

With a few targeted architectural adjustments, you can integrate Little Green Light into your website so that donations, event registrations, and newsletter signups flow into your database cleanly and automatically.

"A donor management system is only as good as the data flowing into it. Clean web integration turns Little Green Light into an automated fundraising powerhouse."

The 2 Ways to Connect Little Green Light with Your Website

1. LGL Forms with Custom CSS Overrides

LGL offers a built-in form builder called LGL Forms that connects directly to Stripe or ProPay. We apply customized, scoped CSS to transform default LGL forms into modern, branded components that match your site's typography, button styles, and color palette.

2. Native WordPress Forms with LGL Webhook Sync

If you prefer using native WordPress form plugins like Gravity Forms or WPForms, you can use LGL’s webhook integration or Zapier connector to submit form entries directly into LGL constituents, gifts, and campaign categories in real-time.

Crucial Rules for Clean LGL Data Sync

• Map Campaigns, Funds & Appeals: Always pass hidden fields for Fund (e.g., "General Fund"), Campaign (e.g., "Annual Gala 2026"), and Appeal to make your fundraising reports accurate.
• Enable Auto-Match Rules: Configure LGL's constituent matching rules to look up existing donor emails and prevent duplicate records.
• Automate Tax Receipts: Use LGL Forms’ built-in receipt templates to send IRS-compliant gift confirmations within 60 seconds of donation completion.
