Processing Redeem IDRX Requests

The typical flow to process redeem requests from your user

To do a redeem, you must first perform a burn transaction on the blockchain, then use the hash of that transaction as a parameter in the POST /api/transaction/redeem-request endpoint.

Here is an example code to perform a burn transaction. In this example, we will be using Alchemy as the RPC provider, and Polygon as the blockchain. Please note that for the bank account hash, the format is {bankName}_{bankAccountNumber}.

Check this page to see the list of chains where IDRX is available

• The balance will be processed and credited to bankAccount max 24 hours after your request is submitted.

• The minimum transaction is 20,000 IDR.

• The Maximum transaction is 1,000,000,000 IDR.

• Redeeming IDRX <= 250 million IDR will be processed in real-time

• Redeeming IDRX 250 million IDR<x<1 billion IDR will be processed only during office hours on Monday-Friday at 08:00-15:00 WIB

• For transactions of more than 1 billion Rupiah, send your request to [email protected] to be processed.

• IDRX is not responsible if a redeem error occurs due to an incorrect bank/e-wallet account number.

After the burning transaction is confirmed on the blockchain, you can use the transaction hash obtained from that transaction to do a redeem request. To get the appropriate bankCode and bankName, you can refer to Transactions Methods API.

import { createSignature } from "./createSignature";
const axios = require('axios');

const apiKey = "{YOUR API KEY}";
const secret = "{YOUR SECRET}";

async function redeemRequest() {
  const path = "https://idrx.co/api/transaction/redeem-request";

    "walletAddress": "0x8BD53F7fF88fD895D3686fe6369a07432822d30F",
  };
  const bufferReq = Buffer.from(JSON.stringify(req), 'base64').toString('utf8');
  const timestamp = Math.round((new Date()).getTime()).toString();
  const sig = createSignature('POST', path, bufferReq, timestamp, secret);

  const res = await axios.post(path, req, {
    headers: {
      'Content-Type': 'application/json',
      'idrx-api-key': apiKey,
      'idrx-api-sig': sig,
      'idrx-api-ts' : timestamp,
    },
  });

  console.log('res.data: ');
  console.log(res.data);
}

redeemRequest();

After a successful request, you will get a response as follows:

{
  statusCode: 201,
  message: 'success',

    id: 100,
    chainId: 137,

    bankAccountName: 'JOHN SMITH',
    bankAccountNumberHash: null,

    deleted: false,
    reportStatus: 'NONE',
    notes: null
  }
}

To check the status of the transaction, you can use the Transaction History API. The redeem request will be then processed shortly after. IDR will be transferred to the specified bank account number.
