## Signed Intent/QR Signature Generation



This API is used to sign customer's and non-verified merchant's QR/Intent URL. Merchants will have to sign their QR/Intent QR using their own private key and they have to share their public key with PSP. This API will create a signature using the PSP's private key and will return the signature in response.
