The Leadfeeder API is a programmatic interface that allows developers and technical teams to integrate Leadfeeder's platform capabilities directly into their own systems, applications, and workflows. Instead of manually accessing data through the Leadfeeder interface, you can use the API to automate processes, build custom integrations, and seamlessly connect Leadfeeder with your existing tech stack.
You can find our new Leadfeeder API documentation here.This API marks the beginning of a new chapter for Leadfeeder as we move toward a unified, API-first platform.
