1. CORS (Most common) Browsers block requests coming from a different origin (domain, port, or protocol). Example: Frontend: http://localhost:3000 Backend: http://localhost:5000 Postman ignores CORS, but browsers enforce it. 2. Missing Authentication Headers Postman sends them manually, but your browser request might not. Check your fetch / axios headers. 3. Wrong HTTP Method Your browser request might be GET but your API expects POST or PUT. Postman allows you to set it explicitly. 4. Preflight Requests (OPTIONS) Browsers send an OPTIONS request first for some cross-origin calls. If your server does not handle OPTIONS properly, the request fails. 5. Cookies / Credentials Issue If your API relies on cookies or sessions, Postman doesn’t have the same cookie restrictions. 6. HTTPS vs HTTP Browsers enforce secure requests more strictly. Example problem: Frontend: HTTPS Backend: HTTP Browser may block it. 7. Content-Type Issues Browser requests may not send correct headers. Content-Type: application/json Postman often sets it automatically. 🐞How to debug? 1. Open Browser DevTools Open your browser and go to: F12 → Network tab Trigger the API request from your frontend. Check: • Request URL • Method (GET / POST) • Status code • Request headers • Response headers • Response body Most issues become visible here. 2. Look at the Console Open the Console tab. Common errors you might see: CORS error Mixed content error 401 Unauthorized Blocked by browser security policy 3. Check if the Browser Sends an OPTIONS Request In the Network tab, see if there is an OPTIONS request before the actual API call. Browsers send this preflight request to check permissions. If your backend doesn’t handle it, the request fails. 4. Compare Headers with Postman Open the same request in Postman and compare: • Authorization header • Content-Type • Cookies • Request body Sometimes Postman sends headers automatically that your frontend does not. 5. Log Requests on the Server Add logs in your backend to see if the request even reaches the server.

HTML parece fácil. A confiança está lá em cima. CSS te coloca no seu lugar com problemas de alinhamento. JavaScript traz erros que você ainda não entende. Aí vem o MERN. Frontend, backend, banco de dados, autenticação — tudo de uma vez. APIs falham, CORS te bloqueia, JWT testa sua paciência. Você acha que o projeto está pronto… e então o deploy quebra tudo. Funciona localmente, trava online. Cada passo não apenas aumenta a dificuldade, ele eleva sua mentalidade. Se você está enfrentando dificuldades, você não está atrasado. Você só está subindo de nível.
