Look up an employer's matching-gift program eligibility using Double the Donation's 360MatchPro API

Steps

1. In your 360MatchPro account, go to Settings > API Keys to retrieve your public key (safe for client-side autocomplete widgets) and private key (server-side use only)
2. For donor-facing employer autocomplete on a donation form, use the public key with 360MatchPro's embeddable search widget/script rather than calling the private API directly from the browser
3. For server-side lookups (e.g. checking a donor-entered employer or email domain against the matching-gift database), call the appropriate 360MatchPro API endpoint using your private key per the API reference at doublethedonation.com/api/360matchpro/apiref.html
4. Parse the response for the company's match ratio, minimum/maximum gift thresholds, and submission instructions/URL
5. Store the returned match-eligibility data alongside the donation record so downstream matching-gift follow-up emails can reference it
6. Confirm current field names and endpoint paths against the live API reference before building, since Double the Donation revises this doc independently of general release notes
