SAP Concur APIs allow clients or partners to access data and functions within the SAP Concur product ecosystem. Through the use of these exposed endpoints and functions you can solve a vast array of different business issues and reporting needs such as:
Once you have an agreement in place SAP Concur will set up a meeting with our technical resource team. They'll go through your requirements with you to develop a plan for creating your app or application connector.
After that meeting you'll receive the credentials necessary to make your first API call, including a
client_secret that you'll use to obtain an
access_token. They'll also set up sandboxes and/or implementation entities,
as needed, for your project and help you work through the development and certification process.
The following terms are used when describing the dev environment that works with the APIs:
Used by a client or partner to interact with the SAP Concur APIs and make test API calls. This is not included with a Sandbox. An app will have scopes assigned to it that dictate the endpoints the app has access to. An app will also have grants that dictate the authentication method used by the app.
The piece of software that communicates with the SAP Concur APIs and your application. This software can be a simple scheduled task, a user executed application, or even a separate module hosted on a public Web Server. For more information see, Callouts and Application Connectors.
Which authentication method the app is allowed to use.
An instance of the SAP Concur production environment that a client or partner can use to gain familiarity with SAP Concur products and create sample trips, expense reports, etc. Typically these are used for partner apps, but in some cases web services clients will be provided with an implementation test site.
Which endpoints the app (not Sandbox) has access to.
We all know you shouldn't write your password on a sticky note and keep it under your keyboard. That said, sometimes convenience overrides common sense. Some things to keep in mind as you create your app:
SAP Concur uses OAuth 2.0 an authorization protocol designed to enable third-party applications to obtain limited access to an HTTP service, either on behalf of a resource owner by orchestrating an approval interaction between the resource owner and the HTTP service, or by allowing a third-party application to obtain access on its own behalf.
The APIs implement OAuth 2.0 because it provides a simple mechanism for end-users to grant a partner application access to their data (protected resources) without sharing their passwords. It also enables the user to grant limited access to their data in terms of scope, duration, and so on. For example, a user (resource owner) can grant a travel app (client) access to her protected travel data stored at SAP Concur (resource server), without sharing her username and password with the travel app. Instead, she authenticates directly with SAP Concur (authorization server), which issues the travel app delegation-specific credentials (access token).
