The Challenge

Inboundy needed a robust backend to handle incoming webhook events, manage user authentication with 2FA, and coordinate complex LinkedIn operations across multiple sub-workflows—all without overwhelming the SaaS with direct LinkedIn API calls.

The Solution

We designed and built a centralized webhook routing system with 8 API endpoints, powered by n8n and backed by Supabase:

Webhook Router: A central entry point receives all incoming events and routes them to the appropriate sub-workflow. Each route handles a specific automation pattern.

Auth & 2FA: The system handles secure onboarding with two-factor authentication, maintaining session tokens and rotating credentials through automated refresh workflows.

Rate Limiting: Daily usage limits enforced via Supabase ensure the system never triggers LinkedIn anti-bot detection. Every action is tracked, queued, and throttled automatically.

The Results

Inboundy now runs reliably with 8 production API routes handling everything from onboarding to automation execution. The gateway processes thousands of events daily while keeping LinkedIn operations safe within platform limits.
