HOW IT WORKS
Payment requests, simplified.
SinhaPay issues an invoice for a specific merchant and customer, then checks submitted payment evidence against authorized merchant data. A transaction is not marked paid merely because somebody entered a transaction ID.
01
Create a request
Your server creates an invoice for the right order and amount.
02
Customer chooses method
Only the merchant's approved wallets appear at checkout.
03
Collect payment evidence
The authorized phone forwards matching transaction metadata.
04
Verify independently
Real payment completion waits for authoritative confirmation.
DEVELOPER EXPERIENCE
Connect with your website or app.
Use a dedicated Invoice API key to generate payment URLs. A separate Verification API key reads the invoice status without granting permission to create charges.
