Authentication

We have 4 method for login:

AuthenticationData.Jwt("jwt here")

AuthenticationData.Mobile("+966500000000")

AuthenticationData.Email("[email protected]")

AuthenticationData.UserEnter.INSTANCE

Allowing your user to login using mobile, email and UserEnter

UserEnter, is a way to allow users to enter their mobile number or email to log in. To enable this feature in the Nearpay dashboard, there are a few steps that need to be followed. Once completed, users can log in from the App using their email or mobile number.

1. Log in to the Nearpay Dashboard.
2. Click on the "Terminals" tab.
3. Select the terminal you want to invite the user to by clicking on its details.
4. Under "Access", select "Invite user".
5. Enter the user's details and send the invitation.

Once the user accepts the invitation, they can log in to the SDK and select the terminal to perform transactions.

Allowing Your User To Login Using JWT

To connect your user device to a terminal ID, use your backend to sign the JWT with the following data:

1. Login to Nearpay Dashboard.
2. Go to the credentials page.
3. You will find the following:
   • Client UUID: you will use as client_uuid
   • JWT Key: Once you click generate, it will download a file which is the private key (pos_key.pem) that you will use to sign the JWT.
4. for terminal_id, you can find all the terminals you have on the terminals page and select one

import * as fs from 'fs';
import * as jwt from 'jsonwebtoken';

function getToken() {
var privateKey: Buffer = fs.readFileSync('./pos_key.pem');

var terminal:any = {
  data:{
    ops: "auth",
    client_uuid: "212f66c6-bbfd-4fc7-9f50-31a749145cd1", // provided by nearpay
    terminal_id: "1000003000000006"// get this number from mada
  }
}

return jwt.sign(terminal, privateKey, { algorithm: "RS256"});
}
