API key management is already available in the admin dashboard. Documentation for that workflow is coming soon and will be added here once available.
API
Overflow provides a REST API that lets your team integrate donor, donation, and other nonprofit data directly into your own systems and workflows. The API uses predictable, resource-oriented URLs, accepts JSON request bodies, returns JSON-encoded responses, and relies on standard HTTP verbs and status codes.
For endpoint references, authentication details, and usage guides, see the full Overflow API Reference.
