Hello,

A referral code is also called an invitation code, and it's a code a company issues its users. They can use this code to refer their friends to the said platform. When a person uses your invitation code to sign up, both of you are usually rewarded with something in terms of discounts, bonuses, or credits.

How to get a referral code:

• Sign up on a platform offering referral rewards, like an app or website.
• After you have registered, look for the "Refer & Earn" or similar component under your account setting.
• Share the referral code with friends or family members

How to make money by reviewing?

• Sign up on websites or portals, that give rewards for writing reviews of products or services
• Once you have used a product or service, write a review about the product or service on the website
• Some web portals pay points, cash or vouchers in exchange for excellent reviews.

Many will always check the terms of a platform for referral and review rewards.
