Steps
Request API access/credentials from your EveryAction or NGP VAN account admin (or APIDevelopers@ngpvan.com) — API keys are tied to a specific committee/organization database
Determine the correct base host: https://api.securevan.com/v4 for most US clients, or the international host for non-US clients
Authenticate using HTTP Basic Auth with your API key formatted per the platform's convention (application name and key combined)
Search for or create the supporter via the People endpoints (e.g. matching by name/email/phone) before creating a contribution, to avoid duplicate person records
POST to /contributions with the required fields: contact (matched/created person), designation, dateReceived, amount, status, and paymentType
Use /contributions/{contributionId}/adjustments to correct an existing contribution rather than deleting and recreating it
Known gotchas
EveryAction and NGP VAN are the same underlying API (Bonterra) but have two separate documentation portals (docs.everyaction.com and docs.ngpvan.com) with the same api.securevan.com backend — confirm which branding your target org actually uses
Contributions require a resolved 'contact' reference; if the supporter isn't matched to an existing VAN ID first, you risk creating duplicate people records
This platform is politically/advocacy-oriented as well as nonprofit-oriented — some fields and compliance behaviors (e.g. FEC-related codes) may appear that are irrelevant to a pure 501(c)(3) fundraising use case
