The Problem
Every nonprofit has unique workflows and internal tools. Pre-built integrations cover common use cases, but custom requirements — like syncing with a proprietary database or triggering internal workflows — need direct API access.
The Solution
Our fully documented REST API with OpenAPI specification gives developers complete control. Build exactly what you need with webhook subscriptions, sandbox testing, and client SDKs in popular languages.
