Debugging & Support

Include X-Request-ID when contacting support

Every response from KhaleejiAPI includes an X-Request-ID header — a unique identifier that lets our support team pull the exact log entry for your request within seconds. Always share it when reporting an unexpected error or unexpected result.

How to capture it

JavaScript / fetch

const res = await fetch("https://khaleejiapi.dev/api/v1/...", {
  headers: { Authorization: "******" },
});
const requestId = res.headers.get("x-request-id");
console.log("Request ID:", requestId);
// → e.g. "req_01j9xkz4vp8..."

cURL

curl -si "https://khaleejiapi.dev/api/v1/..." \
  -H "Authorization: ******" | grep -i x-request-id
# → x-request-id: req_01j9xkz4vp8...

Browser DevTools

Open DevTools (F12) → Network tab → click the failing request → scroll to the Response Headers section → copy the value next to x-request-id.
