Processing mint requests

The typical flow to process mint requests from your user

Using a user account's API key, you can process mint requests for the specified user. To do so, you can use the POST /api/transaction/mint-request endpoint. Here is an example implementation.

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

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

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

  const req = {
    "toBeMinted"               : "51500",
    "destinationWalletAddress" : "0x8BD53F7fF88fD895D3686fe6369a07432822d30F",
    "expiryPeriod"             : 3600, // 1 hour
    "networkChainId"           : "137", // Polygon
    "requestType"              : "idrx", // 'idrx' or empty to receive IDRX, 'usdt' to receive USDT
  };
  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,
    },
  });

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

mintRequest();

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

{
  statusCode: 200,
  message: 'success',
  data: {
    merchantCode: 'D11808',
    reference: 'D11808T8GVTL81VV2U7HV',
    paymentUrl: 'https://app-prod.duitku.com/redirect_checkout?reference=D11808T8GVTL81VV2U7HV',
    amount: '54500.00',
    statusCode: '00',
    statusMessage: 'SUCCESS',
    merchantOrderId: '20231219101707'
  }
}

Note that the amount returned is the amount after fees. The user can then do the payment through the payment page in the paymentUrl. To check the status of the transaction, you can use the Transaction History API. Here is an example code to do so:

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

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

async function transactionHistory(txType) {
  const path = "https://idrx.co/api/transaction/user-transaction-history?transactionType="+txType+"&page=1&take=10";

  const bufferReq = Buffer.from('', 'base64').toString('utf8');
  const timestamp = Math.round((new Date()).getTime()).toString();
  const sig = createSignature('GET', path, bufferReq, timestamp, secret);

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

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

transactionHistory('MINT');

The response as follows:

{
  statusCode: 200,
  message: 'success',
  metadata: { page: 1, perPage: 10, pageCount: 1, totalCount: 1 },
  records: [
    {
      id: 311,
      paymentAmount: 54500,
      merchantOrderId: '20231219101707',
      productDetails: 'Minting IDRX',
      customerVaName: 'JOHN SMITH',
      email: '[e-mail];IDRX',
      minted: false,
      deleted: false,
      chainId: 137,
      destinationWalletAddress: '0x8BD53F7fF88fD895D3686fe6369a07432822d30F',
      toBeMinted: '51500',
      merchantUserInfo: 411,
      createdAt: '2023-12-19T10:17:07.903Z',
      updatedAt: '2023-12-19T10:17:07.903Z',
      paymentStatus: 'WAITING_FOR_PAYMENT',
      expiryTimestamp: '1703197027900',
      reference: 'D11808T8GVTL81VV2U7HV',
      txHash: null,
      qredoTxId: null,
      signedTx: null,
      adminMintStatus: 'REQUESTED',
      userMintStatus: 'NOT_AVAILABLE',
      isApproved: false,
      reportStatus: 'NONE',
      requestType: '',
      refundStatus: null
    }
  ]
}

After a successful payment, IDRX tokens will be minted to the specified wallet address.
