Node.js and SAP Concur

Node.js is a popular framework for creating server-side applications using JavaScript. SAP Concur is a travel and expense management software that helps businesses automate and manage their travel expenses. In this article, we will discuss how Node.js can be used with SAP Concur to simplify and automate the process of managing travel expenses.

Setting up the environment

To use Node.js with SAP Concur, we need to set up a development environment. The following steps will guide us through the process:

1. Install Node.js: Node.js can be downloaded from the official website https://nodejs.org/en/download/.

2. Install the Concur API: The Concur API can be installed using the following command:

   npm install concur
   

   This will install the concur package to our project, which we can then use to interact with the Concur API.

Using the Concur API with Node.js

The Concur API can be used to fetch data, such as travel expenses, from Concur and perform various operations on it. Let's take a look at a simple example of how we can fetch expenses using the Concur API with Node.js:

const Concur = require('concur');

const concur = new Concur({
    client_id: 'YOUR_CLIENT_ID',
    client_secret: 'YOUR_CLIENT_SECRET',
    username: 'YOUR_USERNAME',
    password: 'YOUR_PASSWORD'
});

concur.api('expenseReport/v3.0/expenseReports', {
    method: 'GET',
    headers: {
        'Accept': 'application/json'
    },
    qs: {
        limit: 10
    }
}, function(err, response, body) {
    console.log(body);
});

In the above example, we first import the Concur package using require. We then create a new instance of the Concur class by passing in our client ID, client secret, username, and password.

Next, we use the api method of the concur object to make a GET request to the expenseReport/v3.0/expenseReports endpoint. We pass in the following options to the api method:

• method: The HTTP method used for the request (in this case, GET).
• headers: An object containing any HTTP headers to include in the request.
• qs: An object containing any query string parameters to include in the request.

Finally, we provide a callback function to handle the response. In this case, we simply log the response body to the console.

Conclusion

Node.js is a powerful tool for developing server-side applications, and it can be used with SAP Concur to automate and simplify the management of travel expenses. By using the Concur API with Node.js, we can fetch data from Concur and perform various operations on it, such as creating and approving expense reports.
