Handling Partial Payments

There is a possibility of shoppers making a partial payment when paying using a crypto wallet. We do update the shoppers to complete the partial payment. However, some merchants are okay with whatever the shopper has paid and want to issue goods/services as per the payment amount. In this case, merchants may close the partial payment so that they can give the goods/service for the amount paid by the shopper, and we can settle the partial payments to the merchants. This API will help the merchants to mark a partial payment as closed.

It is advised to merchants that they should give shoppers up to 24 hours to pay the remaining amount before marking the transaction as closed.

The merchants are requested to mark the transaction closed within two weeks of the partial payment by the shopper. After two weeks, the transaction cannot be marked closed.

POST /closePartialTx






Request Body




Merchant Client Id



Encrypted string of offerId by client secret

    "ok": true,

clientSecret: "8e6e7524-202d-424d-b2a2-431ff1117e27" 

Then encrypt this offerId (JSON format) with clientSecret:
