Short version. Free for life. One link per placement. The reward lands in your wallet the moment a sign-up is counted, and you keep all of it.
You do not need followers
Most referrals in India happen in a family group, an office group, a batch group. If you have ever said 'try this app' to a friend, you are a marketer here. Sign in with a code on email or WhatsApp, pick an offer with a reward you understand, share the ready-made message, and see what happens.
How a first offer works
The offer says what the reward is (for example ₹150 per sign-up) and how much budget is left. You get a link. Post it in a group with the message provided. When someone signs up, the reward lands in your wallet, the same moment. You can see opens and results as they arrive.
You can also paste any link you like — a friend's shop, your own page — and get a tracked version with the same live view. It pays nothing unless it is a brand offer, but it shows you how far your sharing travels, which is a surprisingly useful thing to know before you take an offer.
What you can see
Each open with where it came from (WhatsApp, Instagram…) and the city. Who is on the page right now. Each result and its reward. The brand sees the same for your link.
Getting your money
Withdraw from the wallet by UPI or bank transfer. If an order is cancelled the reward is taken back and you can see why. There is nothing to pay, ever.
Being a good referrer
Share things you would use. Say it is a referral link. Do not spam groups. That is the whole rulebook.
