# Processing Redeem IDRX Requests 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}`. {% hint style="info" %} Check [this page](https://docs.idrx.co/introduction/supported-chain-and-contract-address) to see the list of chains where IDRX is available {% endhint %} {% hint style="info" %} * 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\ to be processed. * IDRX is not responsible if a redeem error occurs due to an incorrect bank/e-wallet account number. {% endhint %}

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](/api/transaction-api/get-api-transaction-method.md). ```typescript 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"; const req = { "txHash": "0xa38c057222872d8e3d106ab5f9b86b7d1d6ade72d485eb01366650e45c8a65d1", "networkChainId": "137", "amountTransfer": "21000", "bankAccount": "7255759001", "bankCode": "014", "bankName": "BANK CENTRAL ASIA", "bankAccountName": "JOHN SMITH", "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: ```json { statusCode: 201, message: 'success', data: { id: 100, chainId: 137, userId: 411, requester: 'JOHN SMITH', txHash: '0xa38c057222872d8e3d106ab5f9b86b7d1d6ade72d485eb01366650e45c8a65d1', fromAddress: '0x8BD53F7fF88fD895D3686fe6369a07432822d30F', amount: '16000', bankName: 'BANK CENTRAL ASIA', bankCode: '014', bankAccountNumber: '7255759001', bankAccountName: 'JOHN SMITH', bankAccountNumberHash: null, custRefNumber: '000028880723', disburseId: 17610206, burnStatus: 'REQUESTED', createdAt: '2023-12-19T11:05:42.583Z', updatedAt: '2023-12-19T11:05:42.583Z', deleted: false, reportStatus: 'NONE', notes: null } } ``` To check the status of the transaction, you can use the [Transaction History API](/api/transaction-api/get-api-transaction-user-transaction-history.md). The redeem request will be then processed shortly after. IDR will be transferred to the specified bank account number. \ When redeeming to an e-wallet, the destination field must be filled with the registered e-wallet phone number. The phone number must use the local format starting with `08xx`, with no spaces, dashes, or any special characters. For example, a valid entry would be `081234567890`. Submissions that do not follow this format will be rejected and the redemption request will not be processed. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
