How can we help?

After your payment is confirmed you'll get login details for your merchant dashboard. Log in, add your UPI ID under Settings → UPI IDs, copy your API key, and create your first order or payment link. Most merchants are live within 10 minutes.

• A bank account with UPI enabled
• A UPI ID linked to that account (a merchant/business UPI ID is recommended)
• Optionally, a website or WooCommerce store for the API or plugin

Yes. Every account has sandbox keys. Sandbox orders behave exactly like live ones, and you can trigger a successful payment from the dashboard without moving money. You can also try our public demo.

A merchant or current-account UPI ID from your bank is best, because these have higher daily limits than personal IDs. You can add several IDs and UPIstar will spread payments across them.

UPIstar has no limit. Your bank and the UPI network set per-transaction and daily limits on your UPI ID. Adding more UPI IDs lets you collect beyond a single ID's limit.

Instantly. UPI payments credit your bank account in real time. UPIstar never holds your funds, so there's no settlement cycle.

Yes. Add, pause or remove UPI IDs anytime from the dashboard. New orders use whichever IDs are active.

Ask the customer for the 12-digit UTR (transaction reference) from their UPI app. Open the order in your dashboard, click Verify UTR and paste it. If the amount matches a received credit, the order is confirmed and the webhook fires.

Orders are only marked paid after the credit is matched to your account by amount and reference. Screenshots don't count. Each UTR can be used once, so repeat or edited references are rejected.

Dynamic QR codes lock the exact order amount. If someone pays a different amount manually, the order isn't auto-confirmed and is flagged for review.

Because payments go straight to your bank, you refund customers directly from your own bank or UPI app. You can mark the order as refunded in the dashboard for your records.

• Check that the URL is public HTTPS and not behind a login or firewall.
• Make sure your server returns a 2xx status within 10 seconds.
• Open Webhook Logs in the dashboard to see each attempt's response code and body.
• Use Replay to resend once you've fixed the issue.

A retry can happen if your server took too long to respond. Make your handler idempotent: if the order is already paid, simply return 200.

Compute an HMAC-SHA256 of the raw body using your webhook secret and compare it with the X-UPIstar-Signature header. See the signature guide for code samples.

Go to Settings → API Keys and click Rotate. The old key stops working immediately. Update the new key on your server.

Download the plugin ZIP from your dashboard. In WordPress, go to Plugins → Add New → Upload Plugin, activate it, open WooCommerce → Settings → Payments → UPIstar and paste your API key.

Check that the webhook URL shown in the plugin settings is saved in your UPIstar dashboard, and that a security plugin isn't blocking incoming requests to /wp-json/.
