Could you please be a bit more specific about what you're trying to achieve? Typically with referral codes you'd have a backend API to store the referral codes (normally integrated into another endpoint eg passing it in the body of a Registration request). These can be stored on the client browser as query parameters, cookies, headers, the design is entirely up to yourself as a developer and system architect.
