API Integration

is a technical connection between two software systems that enables them to share data and trigger actions in real time without manual intervention. ConnectGain's comprehensive REST API allows developers to programmatically send messages, create and update contacts, manage deals, trigger automation flows, retrieve conversation history, and access analytics data from any external application or system. The API supports webhooks for real-time event notifications, enabling external systems to react instantly to ConnectGain events. Businesses use ConnectGain's API to build custom integrations with industry-specific software, internal tools, and proprietary systems that are not covered by the platform's native integration library. Detailed API documentation, authentication guides, and sandbox environments are provided to minimize development time and accelerate integration deployment.
