Referral and request referer

A product API request may include a custom referer header.

• Send X-Referrer: your-ref-code, or X-Referer: your-ref-code.
• If both headers are present, X-Referrer is the value that is stored.
• If neither custom header is present, the standard Referer header is stored.
• Requests without a custom header are served as usual.
• Any other header value is stored the same way. your-ref-code is the example value.

A signup link may include a referral code:

https://console.apibricks.io/?ref=your-ref-code

The website also appends ampDeviceId to outbound links. After sign-in, the console saves ref and ampDeviceId with the account email by calling POST /api/attribution/link.
