Introduction

Getting started

Access corporate travel expense and transaction data in real time.

The Invoice API allows clients and partners to view transaction data (a.k.a. “invoice data”, “expense data”) in real-time. This API allows integration with your application to view your corporate travel expenses.

Prerequisites

You’ll need to obtain these from our account or partner manager, as they’re required in every request:

  • API Endpoint
  • Authentication API Endpoint
  • Client Id
  • Client Secret

In addition to the endpoint, you may choose one of our authentication methods. Currently we support OAUTH2 Client Credentials.

Based on your choice, our account or partner manager will provide you credentials and other authentication flow details.

For more information, view our Request authentication & authorization guide or skip ahead to the Postman setup instructions below.

Postman setup

  1. Download the latest version of the Postman application.
  2. Open Postman and import our Postman collection.
  3. Import our Environment JSON file and modify with your client id (ClientId), client secret (ClientSecret), and environment URLs (AuthAPI and ExpensesAPI).

If you’re new to Postman, view the Postman documentation for details on how to configure a collection.

TLS

In accordance with the latest PCI compliance and security standards, the minimum TLS protocol we support is TLS version 1.2.
