Going live

A checklist before real money:

1. A method with Live settings. In Console → Payment methods, switch to Live, fill in the method's live credentials, and Check and turn on. Until one passes, live payments answer live_not_ready. PayLink UPI needs only your business UPI ID.
2. Gateway webhooks. Paste each gateway's live webhook URL from PayLink into its dashboard (they differ from the test ones: …/live).
3. A live secret key (sk_live_…) on your server, from Developers in Live mode.
4. A live webhook endpoint (https), and your server verifying PayLink-Signature with the live whsec_.
5. Fulfil on the webhook, not on the return URL.
6. Risk rules suited to you (start with the common ones) and alerts for success rate and UPI waiting.
7. PayLink UPI: someone checks UPI verification daily, or a script uploads the bank statement.
8. Optionally, your own domain so payers see your name.

Test and Live share nothing but the team and risk rules, so test as much as you like.
