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.

200: OK

{
    "ok": true,
    "result": {
        "success": true
    }
}

400: Bad Request

{
    "ok": false,
    "statusCode": 400,
    "data": {},
    "message": "No partial transaction found"
}

// Example
 
offerId: "d21c44a5-9ff7-44d6-9dbc-158753184d5d"
clientSecret: "8e6e7524-202d-424d-b2a2-431ff1117e27" 

Then encrypt this offerId (JSON format) with clientSecret:
i.e, Encrypt JSON {"offerId":"d21c44a5-9ff7-44d6-9dbc-158753184d5d"} with "8e6e7524-202d-424d-b2a2-431ff1117e27"

And its output will be encryptedReq param 

For above offerId and clientSecret, encryptedReq is "U2FsdGVkX1+T1BocXOZHJA2paoYtiFC1GIl99jjtPQEWuxF2ikm8VT8eaenS5TDc67idkKfwFqBBd9dli/Ssdd28aXp6SKaBEtkkytTAtiA="

Below is the sample postman Request

Copy the following to the Pre-script

var CryptoJS = require('crypto-js');
var data = CryptoJS.AES.encrypt(JSON.stringify({
 offerId: '<<TRANSACTION_ORDER_ID>>'
}), '<<MERCHANT_CLIENT_SECRET>>').toString();
pm.variables.set("encryptedPartialPayload", data);

Sample Curl Request

curl --location 'https://app.rocketfuelblockchain.com/api/closePartialTx' \
--header 'Content-Type: application/json' \
--data '{
"clientId":"<<MERCHANT_CLIENT_ID>>",
"encryptedReq":"{{encryptedPartialPayload}}",
"forceUpdate": false
}'

forceUpdate is an optional parameter and its default value is true. If passed will value false, it will not close partial transaction if there is a refund request on the transaction
