Set up a Linkrunner webhook receiver in a backend app to get real-time install and signup attribution events - detect the backend framework (Express, Fastify, Next.js API routes, NestJS, Flask, FastAPI, Django, etc.), add a route that verifies the linkrunner-key header, and handle the payload idempotently. Use when someone asks to set up Linkrunner webhooks, receive install/signup webhooks, or handle a Linkrunner webhook in their backend.
