Load key certificate

Before calling any APIs, you will need to load your key certificate. You can use this helper function to do so.

import { loadKeyCertificate } from "node-tra";

const { key } = await loadKeyCertificate(
  "YOUR KEY FILE PATH",
  "YOUR KEY PASSWORD"
);

Registration

To get details about your company you need to call registration API. You call this once. You can reuse the result in the next steps.

import { sendRegistrationRequest } from "node-tra";

//test environment details
const hostname = "virtual.tra.go.tz";
const path = "/efdmsRctApi/api/vfdRegReq";

const response = await sendRegistrationRequest({
  tin: "YOUR TIN",
  certKey: "YOUR CERT KEY",
  signKey: key, //key loaded from first step
  certSerial: "YOUR CERT SERIAL",
  hostname: hostname,
  path: path,
});

//if successful, response.success == true
const { success, data } = response;

Token

To upload receipts/invoices you will need to provide a token to TRA API. To get the token call this helper function.

import { sendTokenRequest } from "node-tra";

//test environment details
const hostname = "virtual.tra.go.tz";
const path = "/efdmsRctApi/vfdtoken";

const response = await sendTokenRequest({
  username: "USERNAME FROM REGISTRATION API",
  password: "PASSWORD FROM REGISTRATION API",
  grantType: "password",
  hostname: hostname,
  path: path,
});

//if successful, response.success == true
const { success, data } = response;
