Official server SDKs ship for PHP, .NET, Java, Python, Node.js, and Ruby, plus Accept mobile SDKs for iOS and Android. Authentication uses merchant API Login ID + Transaction Key, with OAuth 2.0 available for partner/Accept integrations. Added to the API Evangelist network from an Insight Partners portfolio lead and enriched from Authorize.net's public developer surface.
