I need a small back-end service that exposes a simple JSON URL returning the current number of followers on my LinkedIn company page, so I can plug it straight into the “Custom Counter” tool mentioned in their article “I need a JSON URL for my Custom Counter, what information should I provide my developer with?”. Core requirements • Source: LinkedIn (company profile) • Data point: number of followers only • Refresh logic: the endpoint must hit LinkedIn’s API every minute, cache the fresh value, and serve it instantly when the Custom Counter polls in real time (I understand LinkedIn itself may not always update instantly; that’s fine). Technical notes • Any stack is fine—Node, Python, PHP, or a lightweight serverless function—as long as the final deliverable is a publicly accessible HTTPS URL returning clean JSON, e.g. { "value": 1234 }. • Handle LinkedIn OAuth 2.0 authentication; I’ll provide the client ID/secret and company URN. • Code must include clear environment variables for secrets and a short README so I can redeploy if needed. Deliverables 1. Source code repository with clear instructions. 2. Deployed endpoint URL ready to drop into Custom Counter. 3. Brief README covering setup, env vars, LinkedIn app configuration, and rate-limit considerations. Acceptance criteria • A GET request to the URL returns valid JSON with the latest follower count. • The value updates when LinkedIn’s figure changes (checked with a manual API call). • No sensitive keys hard-coded in the repo. If anything is unclear, just reference the Custom Counter documentation and we’ll sort it out quickly.
